2.1 LED Display

1) Load on inverter [ LOAD ON INVERTER ](green)

Illuminates when power is supplied from inverter to the critical load. (Indicates the state of inverter transfer switch "52C".)

2) Battery operation [ BATTERY OP. ](yellow)

Illuminates when power is supplied from batteries following a power failure.

3) Load on bypass [ LOAD ON BYPASS ](green)

Illuminates when power is supplied to load devices by static bypass.

4)Overload [ OVERLOAD ](red) Illuminates in overload condition.

5)LCD fault [ LCD FAULT ](red) Illuminates when an error occurs.

6)UPS fault [ UPS FAULT ](red) [Annunciater: intermittent or constant tones] Illuminates when an error occurs in the system. In this case, the details of the error are indicated on the display panel.

2.2MBP Lamp (Maintenance Bypass Pilot Lamp) (7)

When operated in maintenance bypass mode, this lamp will be illuminated.
