Marathon TS 910 - 3.5 DIELECTRIC TESTING

TS 910 TRANSFER SWITCH
PM140 REV 2 14/01/23 6 Thomson Power Systems
REQUIREMENTS FOR UPSTREAM CIRCUIT PROTECTIVE DEVICES of this
manual for further details. Short circuit currents listed for Standard type ATS are
Withstand ratings. Short circuit currents listed for Service Entrance type ATS are
Interrupting ratings based on the ratings of the supplied utility service disconnect
circuit breaker utilized.
WARNING: Do not install the transfer switch on systems with higher available short
circuit current levels than listed below Failure to follow these instructions can
result in death, serious injury, or equipment damage.

3.5 DIELECTRIC TESTING
Do not perform any high voltage dielectric testing on the transfer switch with the TSC
9 controller connected into the circuit as serious damage will occur to the controller.
The control circuit isolation plug connected to the TSC 9 must be removed if high
voltage dielectric testing is performed on the transfer switch.
