Electrical Installation
Any deviation from Palfinger
Liftgates’s recommended power setup
will void warranty and product
liability
unless you have a written confirmation by Palfinger Liftgates that allows you to do specific
changes.
It is the liftgate installer or incomplete vehicle builder responsibility to be certain all chassis
ground systems are adequate for the job. Liftgates with single motor can pull 250 amps at full
load, and liftgates with dual motors will pull 500 amps at full load. These requirements include
liftgate charging systems and OEM chassis battery grounding. Failure to adequately ground
the whole system can lead to burned electrical harness, metal braided hoses, and other
vehicle components.
Never exceed rating of existing fuses located at the battery, control board and/or the pump and
motor which may result in serious damage to the equipment.
Never jump the 150 Amp circuit breaker at the batteries unless otherwise instructed by the
Palfinger Liftgates
technical support group.
Assure all connections are tight and securely sealed.
Heat shrink all cable connection.
Never secure a cable in a way where it can make contact with other wiring, brake, fuel, or air
lines etc. or get pinched against other objects.
2 gauge cable, minimum, is required throughout the motor circuit.
When working on the electrical installation, remove any jewelry, tools, or components that
are conductive to prevent any damage or injuries.
Insure that all wiring is secured and away from heat sources, sharp corners/edges, and
abrasion from moving components during the operation of the liftgate and vehicle.
