5.0 INDICATOR LAMPS
5.1 UTILITY Indicator Lamp
This amber lamp is illuminated when utility power is present (see Figure 5). It signals that you may
transfer the loads to maintenance bypass (UTILITY mode) operation via the rotary switch. During a
utility power outage, this lamp will be off and the UPS will supply battery back-up power to the con-
nected loads.
5.2 UPS Indicator Lamp
This green lamp is illuminated when there is output power available from the UPS (see Figure 5). It
signals that it is safe to transfer the connected loads from utility power back to UPS output power.
