“ON/OFF/STANDBY” Button:
When the UPS system is connected to a live
AC utility power source, the UPS System will operate in one of three modes:
ON, OFF or STANDBY. Refer to the chart below for UPS System operating
characteristics within each mode.

To place the UPS in the ON mode:
Once the utility power source is live, the
UPS System will automatically enter STANDBY mode. Press and hold the
"ON/OFF/STANDBY" button for one second** and then release it to switch
the UPS System from STANDBY mode to ON mode.
OPTIONAL:
If the utility power source is not live, you can "cold-start" the
UPS System (i.e.: switch it directly from the OFF mode to the ON mode by
supplying power for a limited time from its batteries*) by pressing and holding
the "ON/OFF/STANDBY" button for one second** and then releasing it.
To place the UPS in the OFF mode:
With the UPS System in the ON mode and
receiving utility power, press and hold the "ON/OFF/STANDBY" button for one
second** and then release it to switch the UPS System from ON mode to STANDBY
mode. Then, unplug the UPS from the wall outlet. The UPS will be completely OFF.
* If batteries are fully charged. ** The alarm will beep once briefly after the interval has passed.

Basic Operation
Buttons (Front Panel)
If you connect any external batteries, set the Battery
Charge Level Switch (see
) to the down position.
This will increase your UPS’s charger output so the
additional batteries charge faster. Note: the switch to
the right of the Battery Charge Level Switch is inactive
and will not affect UPS operation regardless of its position.
CAUTION! DO NOT set the Battery Charge Level Switch to the
down position without an external battery connected. There is a
risk of damaging the UPS’s internal battery system.

External Battery Connection
(Select Models Only)
Your UPS comes with a robust internal battery system;
external batteries are only needed to extend runtime.
Adding external batteries will increase recharge time as
well as runtime.
The illustration (see
) shows the location of your
UPS’s External Battery Connector, where you will
insert the battery pack cable. Complete installation
instructions for your battery pack appear in the battery
pack’s owner’s manual. Make sure that cables are fully
inserted into their connectors. Small sparks may result
during battery connection; this is normal.
Do not connect or disconnect battery packs when the
UPS is running on battery power.
