Powercom 800VA - Manual (Page 9)

Note: This connection is optional. It is not necessary to use this UPS.
Caution: The telephone line current limiting feature could be rendered
inoperable if improperly installed. Make sure that the telephone line
from the wall is plugged into the connector marked “IN”, and the
device to be protected (telephone, modem, etc.) is plugged into the
connector marked “OUT”.
Caution: This surge protection device is for indoor use only and never
install telephone wiring during a lightning storm.
4.5 Connect to Utility
Connect the AC input power connector to utility power to power up the UPS.
4.6 Charge the battery
The UPS charges its battery whenever it is connected to utility power. For
best results, charge the battery for 4 hours in the initial use.
4.7 Connect the loads
Plug the loads into the output connectors on the rear of the UPS. To use the
UPS as a master on/off switch, make sure all of the loads are switched on.
Caution: Never connect a laser printer or plotter to the UPS with other
computer equipment. A laser printer or plotter periodically draws
significantly more power than when idle, and may overload the UPS.
4.8 Check the Site Wiring Fault Indicator
After plugging in the loads and the UPS, check the site wiring fault indicator
on the rear panel. See section 3.17 for location of the indicator on the back
panel. It lights if the UPS is plugged into an improperly wired AC power outlet.
Wiring faults detected include ground, hot-neutral polarity reversal, and
overloaded neutral circuit.
Note: This device is available on 110 Vac model only.
