UPS.
After that, the fan (in rear panel) will run and all LEDs will light for about 2-3
sec. Meanwhile the CPU inside the UPS setups the initial parameters. User
also can check whether all LEDs are normal or not. The UPS is set in
"STANDBY mode" initially, after a 'bee' is heard, the load LED lights on and
the line LED shows AC utility status. Shown as fig 3-1.
2. Checking the site wiring fault LED (If the function is available)
After the UPS is plugged in , check the site wiring fault LED ( fault LED in
"STANDBY mode"). If the UPS is plugged into an improper wired AC power outlet,
this LED flashes. Shown as fig 3-2.
The detection of site wiring fault includes missing ground, hot-neutral polarity reversal
and overloaded neutral circuit. If it lights up, unplug the UPS and have the site wiring
checked by qualified electrician.
