Wiring
Where do I connect the engine start wires?
The generator starting contact connections are on the controller terminal block. Connect the generator start wires
to terminal block TB7 (TB7-4 and TB7-5 for normally open contacts, and TB7-5 and TB7-6 for normally closed
contacts)
Caution: Make sure both normal and standby source breakers are in the off position.
What generators are compatible with the series 185-transfer switch?
The Generator must be a 2 wire start and connect to the engine start circuit of the transfer switch.
Is the switch supplied with current limiting fuses?
No, suggested fuse ratings listed in table below:
NOTE: When properly coordinated with current-limiting devices, automatic transfer switches can be used on circuits having
available short-circuit currents greater than their unprotected withstand short-circuit current rating. Modern current limiting fuses,
when properly sized, limit the short-circuit current to within the withstand rating of a transfer switch.
What is the DC voltage on the controller?
24VDC.
