Chapter 8 - Local operation
3 Turn the grounding
switch to the
grounded position
when the GROUND
SW RELEASED pilot
light is on.
The auxiliary voltage must be applied, switched on, to operate the
grounding switch.
Do not turn the grounding switch to the grounded position before the
light GROUND SW RELEASED is on. Otherwise, the switch will be
damaged.
The pilot light illuminates only after the fan stops. The fan runs
continuously for a preset time after the main power supply has been
switched off to dissipate the heat from the drive.
If the pilot light does not illuminate and there is reason to believe that
the grounding circuit is malfunctioning, see Chapter 10 -
Troubleshooting and maintenance, 10.3.4 Malfunctioning grounding
switch for further information.
When the grounding switch is in the grounded position, the status
line of the display alternates between DCGnd NOpen,
NotReadyOn, AFE NotRdy.
