Wire resistance must not exceed 0.5 ohm per line. Use stranded wire only. For connection to the screw

terminal, strip the insulation back 3/8 inch (10 mm).

Be sure to check the Interconnect Wiring diagram shipped with the transfer switch.

3.2.2 Remote Start-Stop Connections

Remote starting (for Cummins Inc. water-cooled generator sets only) uses terminals B+, GND (ground),

and RMT of terminal block TB2. Connect these terminals to like terminals on the generator set. Refer to

Interconnect Wiring diagram shipped with the switch. A jumper is shipped with the transfer switch and is in

a small envelope attached to TB2.

• For PCC 3100, 1301, 1302, 2100, 1.X, 2.X, and 3.X genset controls:

◦ install a jumper between TB2-1 and TB2-2 for ground-to-start connection.

• For Detector 12 genset controls:

◦ install a jumper between TB2-2 and TB2-3 for B+ start.

• For PCC 3200 and 3201 genset controls requiring a dry contact start:
