About the device
8. Monitoring the UPS
In order to prevent data loss because of a mains fail-
ure or automatic self-shutdown because of overload/
overheating of the UPS, the UPS can be monitored by
a PC and the included software "ViewPower", which
can shut down the PC safely before any critical level
has been reached.
Simply connect the UPS and the PC (serial port), in-
stall, start and configure the included software to your
demands.
The data cable can be extended by a extension cable.
A maximum total length of 5m without an USB hub shall
not be exceeded.

9. Maintenance

The internal batteries are sealed, maintenance-free
types, which do not require regular maintenance. After
the nominal life time or at premature aging and notice-
able capacity drop (backup time too short), they should
be replaced. This is only done by trained personnel
which is instructed about the replacement procedure.
If the UPS is not used for a longer time, we strongly
recommend charging it completely every 2-3 months,
to maintain battery capacity and life time.

10. Troubleshooting

If the UPS is having an abnormal condition:
• First disconnect the input power line and output
connections and then check whether all connections
have been made properly.
• Check the fuse. If the fuse is blown, then replace it
with one having the same current and voltage rating.
• Remake all connections and try to switch the UPS
on.
If you can't switch on the UPS:
• Make sure you pressing the button firmly and release
the button when the UPS creates a beep sound.
• The voltage of the batteries might be too low due to a
long time storage or non-operation. Let the UPS stay
on mains and without load to recharge the batteries.
• Check the fuse to be blown (650 VA and 1000 VA
models only) or deactivated (1500 VA and 2000 VA
models). The fusible for the smaller models is inside
the AC supply socket.
If you still can't switch on the UPS then contact your
supplier.

If the UPS is having a short backup time:
• 1. Overload condition
Unplug the overload causing computers or other equip-
ment. Make sure the total load capacity is not exceeding
the UPS capacity.
• 2. The batteries have not been charged completely.
Connect the UPS to mains for fully charging the bat-
teries.
• 3. The performance of the batteries may not be good
due to long time use.
Send the UPS to your supplier for replacing the bat-
teries.
