3.1 Unpacking inspection
• Open the UPS package and inspect the contents upon receipt. The accessories
attached to the UPS contain a user manual, RS232 & USB communication cable,
CD-ROM.
• Check if the unit is damaged during transport. Do not power on and notify the
carrier and dealer if find damaged or parts missing.
• Verify this unit is the model you want to buy. Check the model name showed both
on the front panel and rear panel.
Note:
Keep the packaging box and packaging materials for reuse. The equipment is heavy.
Always handle it with care.
3.2 Single System Installation
&
CAUTION
• When connect the loads with the UPS, turn off all the loads first, then connect
power cables and turn on the loads one by one.
• UPS must be connected to the distribution board with overcurrent protective
breaker.
• All power cables should be connected to the protective earthing.
• No matter whether connects the input power cables or not, the UPS output may
present electricity. To make the UPS have no output, turning off the UPS first is
required, and then disconnects the mains power supply.
• To connect inductive loads such as motor and laser printer etc., due to their
excessive starting power, UPS capacity should be calculated by starting power
which normally is twice as much as its rated power.
• If connect to a generator, follow this procedure:
• Turn on the generator, wait until it works normally and connect its output to the
UPS input terminal (Verify that UPS has no-load at this moment), then start up
~7~
