Thomson Power Systems
Close and lock the transfer switch
enclosure door before connecting
power sources.
5. To re-energize the load, remove the padlock(s) from the service disconnect
control switch, and move the switch to the Energized position. The transfer
switch will immediately return to the utility or generator supply if within normal
operating limits.
5.4.4. ADDITIONAL SERVICE DISCONNECT PROCEDURES (S-STYLE
100A-800A OPEN TRANSITION MECHANISM)
If the Service Disconnected pilot light is not illuminated, the service will not have been
successfully disconnected and therefore it is not safe to perform any maintenance until
the following additional procedures are performed:
DANGER
Arc Flash and Shock Hazard. Will cause severe injury or death. Do not open
equipment until ALL power sources are disconnected.
This equipment must be installed and serviced only by qualified electrical
personnel utilizing safe work practices and appropriate Personal Protective
Equipment (PPE). Failure to do so may cause personal injury or death.
1. Open the door to the transfer switch using a suitable tool and opening the
door lock with the key.
2. Visually inspect the actual position of the transfer switch mechanism. If the
position of the transfer switch mechanism is clearly in the neutral position and
the load bus is de-energized on all phases, the service has been successfully
disconnected. Proceed to Step. 4.
If the position of the transfer switch mechanism is not in the neutral position or
the load bus is energized, further procedures are required.
NOTE:
If the position of the transfer switch mechanism is clearly in the Neutral
position, the Service Disconnected pilot light may not have illuminated due to
the following reasons:
a) Utility and generator supply voltages are not present (the TSC 900
requires AC supply voltage to be present to power the pilot light).
b) The pilot light may be burnt out. The bulb should be immediately
replaced with a 6Vdc rated LED bulb.
