GSCM-mini-P Cummins/Onan P4500I generator & Samlex Inverter
Wiring In parallel with engine and start switches
The GSCM-mini-P’s K1 relay contact wire in parallel with the generators Start/Stop push button. It’s K2 relay contact wires to
two control relays, C1’s normally open (87) and common (30) tabs, wires in parallel with the engine switch terminals 1 & 2
which are the power contacts. C2’s normally closed (87a) and common (30) tabs, wires in series with the ground wire that
connects to terminal 5 of the engine switch, when not energized it grounds the ignition coil. Engine switch to be left in the OFF
position.
The GSCM-mini-P’s terminal #6 is connected to terminal #3 (+12vdc) and to Samlex’s normally open relay contact, and the
common contact wires back to terminal #5 on the GSCM-mini-P. The generators AC output is wired to terminals # 9 & 10
providing the run feedback signal. An optional Battery tender/charger is not needed for this option.
The GSCM-mini-P accepts Samlex’s two wire relay contact (maintained run signal) and provides a one second start /stop pulse
as outlined on page 6 GSCM-mini-P opion#2.
