INITIAL BATTERY CHARGING (OPTIONAL)
Your UPS System’s battery is fully charged prior to shipping. However, if your UPS has
been stored for an extended period, recharge its battery for 8 hours. To charge, turn
on the AC Input Breaker. The LCD Display will illuminate and indicate “ON BYPASS.”
DO NOT turn on the AC Output Breaker to apply the load until the battery is fully
charged. Once the UPS is in use, it will charge the batteries and maintain the charge
level automatically.
Operation (Normal Conditions)
TURNING THE UPS ON
• Make sure the UPS is properly installed (see Installation section) and the Manual
Bypass Key is set to NORMAL.
• Turn the AC Input Circuit Breaker ON, then turn the Output Circuit Breakers ON.
• If your AC input is providing power normally within your selected range (see Input
Voltage Selection, pg. 6, and Specs, pg. 17), your connected load will energize.
However, the UPS's inverter is not yet on. Press the front "ON/OFF" switch ON to
begin inverter operation.
• If your AC input is not providing power normally, you have the option of starting
from battery. (Your battery must be at least partially charged for this operation to
succeed.) Press and hold both the "Battery Start" switch and the "ON/OFF" switch
for three seconds to start your UPS in "ON BATTERY" mode. Note that some
electronic equipment may draw more amps during startup; when starting from
battery, consider reducing the initial load on the UPS.
• The UPS will perform a brief self-test and show the results on the LCD Display. (See
Self-Test section, pg. 10, for display sequence.) After a successful self-test, the UPS
will provide AC power from the inverter to your load.
TURNING THE UPS OFF
• Press the front “ON/OFF” Switch OFF. Your load will still be energized. The inverter
is now off, but your UPS is not fully deactivated. The LCD Display will show “ON
BYPASS."
• Turn the AC Input and Output Circuit Breakers OFF. Your load will no longer be
energized, and the LCD display will be dark.
