Control power wiring setup
To maintain the best possible power supply, install the auxiliary batteries as close as possible to the gate.
- Truck installations might not have an auxiliary battery kit (PALFINGER Liftgates
always
recommends
a kit). In this
case you have to run the control power straight off the truck battery.
- Trailer installations always have a trailer battery kit (at least 2 batteries recommended)
Connect your control power to the positive (#2 & #4) and the negative (#1 & gr/ye) post of the batteries.
