When you depress this switch, the lights on the front panel become a bar
graph showing how much of the UPS power is being used. The lights are
in 25% increments. For example, if three lights are on, it shows that the
equipment plugged into the UPS is drawing between 51% and 75% of the
UPS rated capacity. For a 600VA UPS with a computer load, this
represents between 300VA and 450VA.
Whenever you connect new equipment to the UPS, test the load level to
make sure the UPS does not become overloaded. If the UPS is
overloaded, the
“OVERLOAD”
light will turn on and the alarm will sound
continuously. The inverter backup function is automatically disabled until
the overload is removed.
