Operation
Refer to instruction before operating the UPS.
Do not remove the enclosure of the UPS. This system is to be serviced by qualified service personnel

In order to fully disconnect the UPS, press the OFF button. Only after the UPS is shutdown, disconnect
the mains load.
Ensure that no liquid or other foreign objects enter the UPS.
The socket-outlet should be installed near the equipment and should be easily accessible.
ISOLATE THE UNINTERRUPTIBLE POWER SUPPLY (UPS) BEFORE WORKING ON ITS
CIRCUIT.
For cabling, remove the protective panel only after disconnecting the terminal connections and use the
appropriate wires as indicated in Table 1.
