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.
2.4.6 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 2.6.
The detection of site wiring faults includes a missing ground, phase-neutral polarity
reversal and an overloaded neutral circuit. If the LED flashes, unplug the UPS and have
the site wiring checked by a qualified electrician.
This step completes the installation procedure.
