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.
