IMPORTANT SAFETY PRECAUTIONS
THE UPS SHOULD BE SERVICED BY QUALIFIED PERSONNEL

WARNING: This unit contains sealed lead-acid batteries with high
energy and chemical hazards. Carefully read this manual
regarding safe battery handling, maintenance, and dis-
posal. Inspection and replacement should be performed by
qualified personnel only.
Carefully unpack the UPS. Report any shipping damage immediately.
Read the operator’s manual. If you have questions regarding the safe
installation or operation of the UPS, contact Alpha Technologies.
When not in service, charge the UPS batteries at least once every 3
months to ensure optimum performance and battery life.
Install the UPS in a well ventilated area that is free of dust and mois-
ture.
Before installing the UPS, verify the voltage requirements of the
equipment to be protected (load), the AC input to the UPS (line), and
the output voltage of the UPS.
The utility service panel should be equipped with a circuit breaker that
is rated (amperage) for use with the UPS.
Notify fire or emergency personnel that a UPS is installed in the
building by placing a notification or warning label on the electrical
panel.
When connecting a load to the UPS, do not exceed the UPS’s output
rating.
Use proper lifting techniques when handling the UPS or external
