3.12. DIELECTRIC TESTING
Do not perform any high voltage dielectric testing on the transfer switch with the TSC 900
controller connected into the circuit as serious damage will occur to the controller. All AC
control fuses and control circuit isolation plugs connected to the TSC 900 must be removed if
high voltage dielectric testing is performed on the transfer switch.
3.13. SEISMIC ANCHORING
Model TS 970 Automatic Transfer Switches in "standard" enclosures are seismic certified
under AC156 building code for non-structural components.
Standard enclosures are all transfer switch enclosures Thomson Power Systems offers in
NEMA 1, NEMA 2, NEMA12 and NEMA 3R for the above listed product.
The transfer switch must be installed per the anchoring details provided for seismic
qualification. The equipment can be mounted in alternate means and still qualify if a qualified
Civil Engineer designs the alternate method of anchoring.
