100 Introduction  
This manual explains how to start your FERRUPS, interpret its status lights, use its display and communication  
features, and get assistance if you have a FERRUPS problem. This manual also includes specifications and  
warranty information. If your FERRUPS is not a soft-wired (plug-in) model, your electrician should install the  
FERRUPS using the Installation Manual included with your unit. If your UPS has one or more separate battery  
cabinets, you should also use the instructions in the Installation Manual to connect the cabinet(s) to the  
FERRUPS.  
To find information in this manual, use the contents above.  
Best Power is committed to outstanding customer service. If you have a problem or question, our Worldwide  
Service center is happy to help you. Simply refer to the list of Best Power offices at the beginning of this manual

300 Starting the UPS  
Note: If you plan to store your UPS, the storage temperature must be between –20° and +40° Celsius (–4° and  
+104° Fahrenheit). If the UPS does not have internal batteries, you can store it at –20° to +60° C (–4° to  
+140° F). The batteries must be recharged every 90-120 days. To recharge the batteries, start the  
UPS and let it operate for 8 hours. (If the batteries are in a separate cabinet, make sure the  
cabinet is connected to the UPS.)  
Before you start the UPS, make sure the temperature is 0° to 40° Celsius (32° to 104° Fahrenheit). The relative  
humidity must be 0-95% without condensation. The air must be free of dust, chemicals that corrode, or other  
contaminants, and it must be free to move around the UPS.  
CAUTION  
To avoid possible equipment damage or personal injury, assume that the FERRUPS terminals or receptacles  
(outlets) may have AC voltage present whenever AC input voltage or DC battery voltage is supplied.  
FERRUPS can provide output voltage from its batteries even when there is no AC input voltage. When AC  
input voltage is available, FERRUPS can provide output voltage even when its batteries are disconnected. To  
make sure there will be no UPS output voltage, always disconnect the AC input source; if you have a separate  
battery cabinet, you must also shut off the DC switch or disconnect the battery cabinet from the UPS.  
To reduce the risk of electric shock, install the UPS in a temperature-controlled indoor area free of conductive  
contaminants.  
When the UPS is shipped, two sections of the front panel are not attached. Attach the front panel  
sections before starting the UPS.  
When you receive the FERRUPS, two sections of the front panel  
1
2
are not attached. You will find the panel sections in the packing  
material on the top of the UPS.  
Attach the smaller of the two panels to the middle section. To do  
this, fit the slots on the back of the panel over the metal tabs on the  
front of the UPS. Then, push the panel in until it snaps in place.  
Make sure the panel is completely attached with no gaps between  
the panel and the UPS. Attach the larger of the two panels to the  
bottom section of the UPS.  
If your UPS is not a soft-wired (plug-in) model, an electrician must install the UPS and connect the  
equipment you want to protect. See the FERRUPS Installation Manual. After the UPS has been installed,  
make sure the bypass switch is turned to “LINE,” skip step 3, and go to step 4 below.  
If your UPS is a soft-wired (plug-in) model, turn off the equipment you want to protect.  
5
 
 
Models with permanently attached power cords (shown):  
Plug in the UPS. If the plug on the UPS’ power cord does not  
match your outlet (receptacle), an electrician must install the  
proper outlet.  
3
Models with power cords that must be plugged in:  
Do not use the cord that came with your UPS to plug it in; this  
cord is for connecting your equipment to the UPS. Your computer,  
or the equipment that you want to protect, should have a power  
cord that you can unplug or disconnect. Disconnect this cord from  
your equipment, connect the cord to the back of your UPS, and  
use it to plug in the UPS. Once you have plugged in the UPS, the  
green light on the front panel should be on. (If you need to order a  
UPS power cord, call the nearest Best Power office.)  
If your FERRUPS has one or more separate battery cabinets, the battery  
packs should already be installed. (See the Installation Manual.) Find  
the red DC switch on the back of each battery cabinet. Insert the key into  
the DC switch and turn it all the way to the right (clockwise); then, pull  
the switch out to turn the DC on. When you want to turn the switch off,  
simply push it in — you do not need the key to turn DC off.

DC Switch  
Off  
On  
At the UPS back panel, press and hold the On/Off switch until the unit  
starts. AC input power must be present for the FERRUPS to start.  
When the unit starts, it runs on battery power briefly; then, the green  
light on the FERRUPS front panel will be on to show the unit is  
running on AC line input. Whenever the yellow light is on, the unit is  
running on battery power because of a power outage or power problem.  
When the green light is on, the display will show the following:  
On/Off

FERRUPS automatically charges the batteries  
whenever AC input power is available. If this is the first time  
you’ve started the FERRUPS, let it charge the batteries for 8 hours  
before you go on. You can use the UPS right away, but its battery  
backup time (runtime) will be shorter until the batteries are fully charged.  
LINE  
If your unit has a bypass switch, check for a red button next to the switch  
(shown). If the bypass switch has a red button, press it, then turn the switch  
to “UPS.” If not, simply turn the switch to “UPS.”

“UPS”  
FERRUPS comes with a CheckUPS software package that  
lets you connect the FERRUPS to your computer and  
monitor UPS operation and power conditions. During longer  
power outages, CheckUPS also can shut down your computer  
automatically before the UPS runs out of battery backup time.  
To start using CheckUPS, find the interface cable packed  
with your CheckUPS software. Connect the “UPS” end of  
this cable to the FERRUPS’ port, and connect the other end  
of the cable to your computer.  
To your  
computer  
To install the CheckUPS software, see the instructions in the CheckUPS CD case.  
The FERRUPS is now providing continuous, computer-grade power to your equipment. It is ready to  
provide battery backup power when needed. Please fill out the warranty registration card in this manual  
and return it to Best Power within ten days of installation.

400 Using the FERRUPS’ Front Panel Lights  
The FERRUPS display includes three lights that show you the status of FERRUPS operation.  
Alarm Light  
Battery Light  
Line  
(AC Input)  
Light  
The red Alarm light means the UPS has detected a problem. When this happens, the display shows an alarm  
message, and the UPS beeps the Morse Code for the alarm. See Section 600.  
The yellow Battery light means the UPS is operating on battery power, either because there is a power outage  
or because the available AC input power is not usable. When this happens, the display shows “On Battery,” the  
runtime, and the battery voltage. (You can press the bottom right buttton to switch to the menu display; see  
discharge. If the batteries discharge, the UPS will sound alarms shortly before shutting down.  
The green AC Line light means the UPS is using the available AC input power. The UPS conditions the power  
before providing output to your equipment. While the FERRUPS is using AC input power, it displays “System  
Mode Auto” and whether the battery charger is on or off. You can press the bottom right button to switch to the  
menu display; see Section 501 for more information.  
500 Using the Display  
This section explains how you can use the FERRUPS’ front panel display to get more information about  
FERRUPS operation or to change settings. You can use the display to enter a password, display and change  
system settings (parameters), and display system logs.  
501 Displaying and Moving through the Menus  
The FERRUPS display groups information in 7 different menus. See the Menu Map on page 11; the items  
numbered 1-7 in the left column of this diagram are the top-level menus. For example, 2 System Status is the  
System Status menu. To the right of this menu in the Menu Map, you will notice a list of items that are part of  
this menu. Some menus, like menu 5, System Config, have submenus (Gen Sensitivity; Sys Test, Inv, Chg;  
System Mode Control; Alarm and Shutdown; and Calibration Factors). Others simply have lists of items directly  
below the top level menu.  
When you start the UPS, the display shows “Best  
Power,” the mode, and whether the charger is on or off.  
To change to the menu display, press the bottom right

To scroll down through menus or menu items in the same level:  
Press the t button on the right side of the display.  
To scroll up through menus or menu items in the same level:  
Press the s button. You can also look at the bottom line of the display, which includes the words “Top”  
and “ESC.” The button under the word “Top” will take you to the top of the list of items in the menu  
level.  
Example: When you switch to the menu display, the display shows the top item in the top level (1,  
Enter password). To scroll down to menu 2 (System Status), press the t button. Press this  
button again to scroll down to menu 3 (System Status Info), and so forth. To scroll back up to  
menu 1, press s twice or press the button below “Top.”  
To display the items in a menu or submenu:  
Go to the display that represents the menu or submenu, and press the ¿ button.  
Example: The interface starts at the top item in the top level (1, Enter password). If you scroll down to  
menu 2, the display shows “System Status.” To display the items in the System Status menu,  
press ¿. You can then scroll down and back up through the items in this menu.  
To move back up a menu level:  
Notice that the bottom line of the display shows “Top” and “ESC.” If you press the button under “ESC”  
(the right button below the display), the display goes back to the next higher menu level.  
502 Displaying a Parameter by Entering the Parameter Number  
For service purposes, parameters are also assigned sequential numbers (1-337). If you know a parameter number  
and want to go directly to that parameter, you can use menu 7 in the top level menus (Parameters) to display the  
parameter. Simply follow these steps:  
1. Scroll down to menu 7, and press ¿. The third line of the display will change to “parameter = 000,” and the  
bottom line of the display will change to “<– –> ESC” to show the functions of the three buttons below  
the display.  
7
Enter A Parameter  
parameter # 000  
<–  
–>  
ESC  
2. Use the <– and –> buttons to scroll through the digits to the left and right, and use the s and t buttons to  
increase or decrease the value of each digit. When the three digits show the number of the parameter you wish  
to display, press ¿.  
Example: To display parameter 32, you need to change the three digits (000) to “032.” Since you do not  
need to change the first digit, press the button below –> to move the cursor to the second digit.  
Then, press s three times to increase the second digit to “3.” Next, move to the third digit, and  
press s twice to increase this digit to “2.” Now, the display shows “parameter = 032.” Press ¿.  
The parameter’s short name and value will appear on the third line of the display.

503 Entering a Password  
Before you can change the setting of some FERRUPS parameters or menu items, you must enter a password. To  
do this, follow the steps below. The User password is 0377.  
1. If the display is not already showing the menus, press the bottom right button (below the word “Menu” on the  
bottom line of the display). Go to the top item in the top menu level, “Enter Password.” (If you are not sure  
how to do this, see Section 502 and the Menu Map on page 11.)  
2. Press ¿. The display will show the following:  
1 1  
Enter Password  
0000  
<–  
–>  
ESC  
A cursor will appear in the “0000” line of the display.  
3. The bottom line of the display will show you which buttons to use to move through the password’s digits  
(0000) to the left (<–) and to the right (–>). Move the cursor to the first digit you want to change, and use the  
s and t buttons to increase or decrease the number. Repeat this step for each digit that needs to be changed.  
4. When the number matches the password you want to enter, press ¿. The password name (such as “User”) will  
appear in the upper right corner of the display to remind you which password has been entered. If you begin  
entering a password and decide not to enter it, press the bottom right button on the display (the button under  
“ESC” for escape).  
Example: To enter the User password (377), use the button below “–>” to move to the second digit in  
“0000”; then, press the s button three times to increase this digit to “3.” Next, press –> to move  
to the third digit, and press s seven times to increase this digit to “7.” Then, press –> again to  
move to the last digit, and press s seven times to increase this digit to “7.” The display should  
now show “0377.” This is the User password. Press ¿. “User” will appear in the upper right  
corner of the display to show you the User password has been entered.  
504 Changing a Parameter Setting  
Some of the items that you can view on the front panel display can be programmed (such as the time, date, and  
year). To do this, follow the steps below. (If you are changing the time and date, see step 10 in Section 200.)  
Note: You must enter a password before programming many of the menu items. To find out which password is  
required, see Section 505. To enter the password, see Section 503.  
1. If the display is not already showing the menus, press the bottom right button. Find the item you want to  
change in the Menu Map (page 11). This tells you where the item is in the menu structure. Next, use the s,  
t, and ¿ buttons to move to the item you wish to change. If you are not sure how to do this, see Section 501.  
2. Press ¿. If you can change the item without a password (or with the password you have already entered), a  
cursor will appear in the value that you can change. The bottom line of the display will change to  
<– –> ESC”. Use the buttons below “<–” and “–>” to move the cursor to the left and right, and use the  
button below “ESC” to escape and discard any changes you have made. See the drawing on the next page,  
which shows what the display would look like if you were changing the time.

506 Reading the FERRUPS Logs  
Your FERRUPS makes an entry in its logs every time it sounds an alarm or runs on inverter (battery  
power). This information can help diagnose power problems. You can display both the Alarm and Inverter  
logs at the unit’s display panel; both logs are in menu 6.  
Inverter Log  
The Inverter Log is in menu 6, submenu 2. To display the log, follow these steps:  
1. Press the bottom right button (below “Menu” on the display) to switch from the normal display to  
the menus. The display will show the top menu, “1 Enter Password.”  
2. Press t five times (until the display shows “6 System Logs”).  
3. Press ¿. The display will show “6 1 Data Log.”  
4. Press t once. The display will show “6 2 Inverter Log.”  
5. Press ¿. The display will show the first entry in the inverter log.  
The log stores up to 16 entries. You can use the s and t buttons to scroll up and down through the log  
entries. Each entry shows the inverter code, then the date the unit ran on inverter, the time it ran on inverter  
(in 24-hour time), and the duration (in hours, minutes, and seconds.) For example, one entry might look like  
this:  
l 0205 0951 001505  
In this example, “l” means the FERRUPS went to battery power because it lost AC input power. (See  
the table on the next page.) If the unit was still running on inverter (battery power), there would be an  
asterisk (*) after the “l.” “0205” means the date of the battery power operation was February 5 (2/5).  
“0951” means the inverter ran at 9:51 a.m. “001505” means the inverter ran for 0 hours, 15 minutes,  
and 5 seconds.

If not, follow the steps below to display the log, follow these steps:  
1. Press the bottom right button (below “Menu” on the display) to switch from the normal display to  
the menus. The display will show the top menu, “1 Enter Password.”  
2. Press t five times (until the display shows “6 System Logs”).  
3. Press ¿. The display will show “6 1 Data Log.”  
4. Press t twice. The display will show “6 3 Alarm Log.”  
5. Press ¿. The display will show the first entry in the alarm log.  
The log stores up to 16 entries. You can use the s and t buttons to scroll up and down through the log  
entries. Each entry shows the alarm code, then the alarm date, the alarm time (in 24-hour time), and the  
duration (in hours, minutes, and seconds.) For example, one entry might look like this:  
a 0205 0951 001505  
In this example, “a” means the FERRUPS sounded alarm A (Low Battery). (See the alarm table in  
Section 600.) If the alarm was still active, there would be an asterisk (*) after the “a.” “0205” means  
the alarm sounded on February 5 (2/5). “0951” means the alarm sounded at 9:51 a.m. “001505” means  
the alarm was active for 0 hours, 15 minutes, and 5 seconds.

700 Communication  
701 Communication Options  
Best Power offers several methods of communicating with your FERRUPS:  
CheckUPS Software: Each FERRUPS unit ships with CheckUPS power monitoring and unattended  
shutdown software. To begin installing CheckUPS, see the instructions in the  
CheckUPS CD case.  
CheckUPS uses an RS-232 serial link to communicate with the FERRUPS, and it  
provides you with up-to-date graphics of UPS power and system data and power  
flow. CheckUPS also gives you a complete record of critical power events, and it  
notifies you of important UPS or power information. If there is a power outage and  
the FERRUPS battery power becomes low, CheckUPS can automatically shut down  
your computer system before the UPS Low Battery shutdown to protect your data.  
RS232  
Communication:  
You can connect a terminal or a computer with terminal emulation software to the  
FERRUPS’ communication port. This allows you to receive information from the  
FERRUPS or send commands in order to display and program parameters. For more  
information, call the nearest Best Power office.  
19  
 
 
Optional Interface Kits:  
For computer systems that already have UPS monitoring software, Best  
Power offers interface cable kits for connecting the FERRUPS to your  
computer system. The kit includes the cable, adapters, and instructions.  
Optional Internal Bestlink™  
SNMP/Web Adapter:  
Using Simple Network Management Protocol (SNMP), system  
administrators can easily monitor and manage remote UPS units that protect  
key network devices like servers, routers, and hubs. Best Power’s SNMP  
Adapters provide a self-contained link between the FERRUPS and an  
Ethernet or Token Ring LAN/WAN. The adapters allow the system  
administrator to communicate with the FERRUPS even after the protected  
device goes down. The SNMP adapter displays over 60 Management  
Information Base (MIB) variables to give the system administrator  
information about UPS operation.  
BestDock™  
FERRUPS has a communication slot that allows quick installation of an optional  
SNMP card.  
Emergency Power  
Off (EPO):  
You can connect your FERRUPS to your Emergency Shutdown switch to provide a  
method for emergency FERRUPS shutdown. This connection shuts down the  
FERRUPS output. See the Installation Manual to make the connection.  
702 DB9 Port Pin Functions  
The table below explains the functions of the pins on the FERRUPS’ DB9 port. This port is on the  
FERRUPS’ back panel. The functions of pins 1 and 2 change depending on the communication mode.  
When you receive the UPS, it is set up for RS232 mode. However, if you want to use the alternate  
functions of pins 1 and 2, you can change the mode by following the steps on the next page.  
Pin Function  
1
In RS232 mode, this pin receives incoming RS232 communication data.  
In Extended Contact Mode, this pin can cause a remote shutdown. If the UPS is using battery power and a  
+12-volt DC signal is applied to this pin for 5 seconds, the UPS will shut down 20 seconds later. When the  
power outage ends, the UPS will automatically restart after 15 seconds. Signal and shutdown times and  
automatic restart are programmable; for more information, call the nearest Best Power office.

800 Maintenance and Service  
801 Regular Maintenance  
Best Power designed your FERRUPS to provide years of trouble-free operation. Its microprocessor will  
check the batteries and inverter at programmable intervals to ensure proper operation. In fact, you’ll  
probably find that your FERRUPS requires less maintenance than any of your other computer peripherals.  
Nevertheless, your FERRUPS does require some attention in order to provide you with excellent service.  
Best Power recommends that you schedule a Preventative Maintenance check at least every six months. At  
this check, the service technician should follow Best Power’s Recommended Maintenance Schedule, which  
includes the following:  
• Inspect and clean the unit.  
• Inspect and record the alarm and inverter logs.  
• Check the batteries.  
• Check the AC and DC meter functions and recalibrate if necessary.  
• Perform a system test.  
• Check and record the values of the parameters in menu 3 on line and on inverter.  
The technician must observe important safety precautions while performing these checks. For more  
information on what your technician should do in a Preventative Maintenance check, or to schedule Preventative  
Maintenance with a Best Power-authorized field service representative, call Best Power’s Worldwide Service.  
We’ll be happy to help you.
