Introduction

The UNITY/I™ UPS is easy to start and operate. Once you start the UPS, it provides continuous, computer-

grade power to your equipment. The UPS keeps you informed of its status with its front panel lights, four-digit

display, and audible signals (beeper). Using the display and front panel keys, you can display UPS information

and program some features.

This manual tells you how to start and operate the UNITY/I UPS. Begin with Section 100, “Starting the

UNITY/I UPS,” which will help you determine whether you need to do any installation before you start the

UPS.

001 Storing the UNITY/I UPS

If you are not going to use the UPS right away, store it between -20° and +40° Celsius (-4° to +104° F). If you

remove the batteries and store them separately, you can store the UPS at -20° to +60° Celsius (-4° to +140° F).

Batteries have a longer shelf life if you store them below 25° Celsius (77° F).Recharge stored batteries every

90 to 120 days.

100 Starting the UNITY/I UPS

If your UNITY/I UPS does not have an input line cord and plug, it is a hardwired unit and must be installed by a

qualified electrician (see the

UNITY

/I Installation Manual). After a qualified electrician has installed the UPS,

or if the UPS has an input plug, follow the instructions in this section to start the unit.

Make sure that the UPS is near the equipment it will protect. Leave at least 4 inches (100 mm) space on top of

and behind the UPS for ventilation. Do not put the UPS near a source of heat.

Make sure that the temperature is 0° to 40° Celsius (32° to 104° Fahrenheit) and the relative humidity is 0 to

95% without condensation. The air must be free of dust, chemicals that corrode or other contaminants. Air must

be free to move around the unit. The batteries’ service life is longer if the operating ambient temperature

stays below 25° C (77° F).

101 Startup

1If you have a UT3K, UT4K or UT5K:Attach the stabilizer

bracket to the back of the UPS (see Appendix B).

2Open the UPS’ front door by pulling the top of the door

toward you (see Figure 1 to find the door). Make sure that

the keyswitch inside the front door is turned to “Off” (see

Figure 2).

3If your UNITY/I has an input line cord and plug:Plug in

the UPS. If the plug does not match the wall outlet, have a

qualified electrician install the proper wiring and outlet.

If your UNITY/I is hardwired (does not have an input line

cord and plug),an electrician should have installed the UPS.

An external bypass/AC disconnect switch should be mounted

on the wall nearby (see Figure 3). Turn the UPS AC LINE

DISCONNECT SWITCH to “ON” and the UPS BYPASS

SWITCH to “OFF.”

4If you have an external battery pack(s)(see Figure 4), refer to the

installation instructions that came with your battery pack(s). Then continue

with the steps below:

a. After completing the battery pack installation, hold down the Precharge

switch on the front of the battery cabinet for five seconds (see Figure 5).

b. Insert the key into the main DC switch on the front of the battery

cabinet. Turn it clockwise, then pull the switch out toward you. The

ON-LINE light will light on the battery pack cabinet.

5Turn the keyswitch inside the front door of the UPS to “Auto” (see Figure

6). The yellow BATTERY light will turn on briefly, then the green LINE

light will turn on.

The four-digit display will show the estimated runtime

in minutes and seconds (see Figure 7). For now, the

estimated runtime is high because there is no equipment

drawing power from the UPS. If the red ALARM light

is on,see Section 204 before you go on.

Note:Do not continue until the green LINE light is on. The UPS is set at the factory to automatically select

its output frequency; to do this, the UPS mustrun on AC line. If the UPS does not run on ACline the

first time you start it, you must either set parameters 14 and 15 or wait until the green LINE light

comes on before you switch on the connected equipment. To set the parameters, see Section 302.

6Once you switch on the unit and the LINE light comes on, the UPS will begin to charge the batteries. If this

is the first time you have started the UPS, let the UPS run on line for at least 24 hours to charge the

batteries. You may use the UPS right away; however, its battery runtime will be reduced until it fully

charges the batteries.

7If your UNITY/I has receptacles on the back,switch off the equipment you want to connect to the UPS.

Then, plug the equipment into the receptacles on the back of the UPS and switch on the equipment. If the

red ALARM light comes on, see Section 204.

If your UNITY/I does not have receptacles on the back,the electrician who installed the UNITY/I should

have connected your equipment to it. Turn the UPS BYPASS SWITCH (see Figure 3) to “UPS.” Then,

switch on the equipment connected to the UPS. If the red ALARM light comes on, see Section 204.

The UNITY/I UPS is now providing continuous, computer-grade power to your equipment and is ready to

provide battery backup power when needed.

Note:You may occasionally hear short “clicking” sounds inside the unit; these clicks are a normal part of

unit operation.

8If you plan to use CheckUPS software, connect the interface cable from the UPS to the computer system,

with the “UPS” end connected to the UNITY/I.

Using CheckUPS with Windows 95:Shut down your computer and insert the CheckUPS CD. Restart the

computer. Follow the instructions in the CheckUPS package.

Using CheckUPS withoutWindows 95:Start the computer and follow the instructions in the CheckUPS

package.

9Fill out the warranty registration card in this manual and return it to Best Power. Please return the registra-

tion card within ten days of installation.
