3 Installation

• Take your UPS out of its packing.
• Make sure the mains supply voltage is identical to the one indicated in the label placed on the
rear of the UPS.
• Switch on your UPS with the ON/OFF button and check it operates correctly with the mains
(green LED on).
• Switch the UPS off by pressing the ON/OFF button until the LED shuts down.
• After switching off the UPS, connect the load power cable to the UPS output using the outlet
located on the right side of the UPS.
• Switch on your UPS and then the load to check it operates correctly with the mains (green LED on).
• Keep the UPS on for 8 hours to recharge battery before using it.
• UPS can also be used before battery is completely charged, but in this case back up time availa-
ble during black out will be shorter.
CAUTION
While wiring the outlet line, make sure the total length of the cable, from the UPS to the
farthest utility, does not exceed 10 metres.
NOTICE
Never disconnect the 230 V power plug while the UPS is operating since this would
disconnect the earthing protection both from the UPS and from the loads connected to it.
