MAINS Indicator Lamp
This orange lamp is illuminated when mains power is present (see Figure 7). It signals that
you may transfer the loads to maintenance bypass (MAINS mode) operation via the rotary
switch. During a mains power outage, this lamp will be off and the UPS will supply battery
back-up power to the connected loads.
UPS Indicator Lamp
This green lamp is illuminated when there is output power available from the UPS (see
Figure 7). It signals that it is safe to transfer the connected loads from mains power back to
UPS output power.
