Any standard contactor can be used. Since inverter current flows through the AC outputs of the MultiPlus-II units, ensure the external transfer contactor wiring is appropriately sized and symmetrical. Connect the contactor coil directly to the NO and COM terminals of the MultiPlus-II "AUX RELAY" terminals of the L1 phase master unit.
Connect one side of the contactor power terminals to the AC supply. Connect the other side of the contactor power terminals to the AC-OUT terminals or the MultiPlus-II units and the AC loads. Protect the AC output wiring with a circuit breaker suitable for the expected load and wire gauge.
The battery and the traction inverter are electrically isolated by main contactors when the vehicle is switched off for safety reasons. The main positive contactor is between the positive battery pole and the traction inverter while the main negative contactor is between the negative battery pole and the traction inverter.
Connect the contactor coil directly to the NO and COM terminals of the MultiPlus-II "AUX RELAY" terminals of the L1 phase master unit. Fuse this wire with a 2A fuse. Connect one side of the contactor power terminals to the AC supply.
