2.4.6 Connecting to the utility power supply
1000/1500VA:
Use a suitable power cord, and plug it into the input socket (see fig. 2.6)
2200/3000VA:
The UPS is equipped with a fixed input power cord.
1. Plug the input power cord into a working three wire, grounded AC wall outlet. Do not
use extension cords.
2. Turn on the input breaker (if the breaker can be turned on) on the rear panel of UPS.
After that, the fan (in rear panel) will run and, as a front panel test, all LEDs will light
up for about 2-3 seconds. The UPS starts up in ‘STAND-BY’ mode and the battery
will be charged. See fig 2.7.
Though the batteries (the internal energy reserve) were fully charged when the UPS left
the factory, they might have lost some energy during transport and/or storage. It is
recommended to allow the UPS to recharge the batteries for at least 6 hours. This way
you ensure that the UPS can provide sufficient runtime in case of a utility power failure.
2.4.7 Checking the site-wiring fault LED
When the UPS is still in ‘STAND-BY’ mode, check the site-wiring fault LED. If the UPS
is plugged into an improperly wired AC utility power outlet, this LED flashes as shown in
Fig 2.8.
The detection of site wiring faults includes a missing ground, phase-neutral polarity
reversal and an overloaded neutral circuit. If the LED lights up, unplug the UPS and
have the site wiring checked by a qualified electrician.
This step completes the installation procedure.
