On/Off Switch
The GT100
incorporates a maintained position
ON
/
OFF
switch located on the left front
door, under the UFCU. Under normal operating conditions, the
ON
/
OFF
switch is in the
ON
position. Turning the switch to the
OFF
position will initiate an immediate controlled
shutdown of the GT100
and open both the main AC and DC contactors within the unit.
The main AC and DC contactors cannot be closed unless the switch is in the
ON
position.
The GT100
is prevented from being restarted until the
ON
/
OFF
switch is turned back to
the
ON
position.
Emergency Stop (E-STOP)
Provisions are supplied for adding a remote emergency stop. Circuit termination and
signal type are identified in Table A-8 on page A–6
Auxiliary Enable/Disable
The GT100 also has provisions for installing an auxiliary Enable/Disable switch in series
with the local control. This is advantageous for coordination of the GT100 at specific
installations where a pre-existing back-up emergency generator is present. Circuit
termination and signal type are identified in Table A-8 on page A–6
WARNING: Shock Hazard
Turning the ON/OFF switch to the OFF position does NOT remove all hazardous voltages
from inside the inverter. Before attempting to service the GT100, follow the de-energize
Lockout and Tag procedure on page xi.
