4 If 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.
Keyswitch
Figure 5
Turn the keyswitch inside the front door of the UPS to "Auto" (see Figure 6). The yellow
5
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 must run on AC
line. If the UPS does not run on AC line 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.
6 Once 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.
If your UNITY/I has receptacles on the back, switch off the equipment you want to connect to the UPS. Then, plug
7
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.
