It is good practice to run dual cables; this is:
1.
a (+) battery cable from the main battery fuse to the incoming main terminal of the motor solenoid.
2.
a (-) ground cable, from the negative terminal of the batteries to the negative terminal of the electric motor.
•
A short (-) ground cable to the vehicle chassis is prone to oxidation, bad contact, and failure. Moreover, it is not allowed on many
modern commercial vehicles.
•
On DH-R* liftgates, the (-) ground cable is routed directly from the batteries to the negative terminal of the electric motor.
•
Foresee a flexible protective conduit over the full length of the (+) battery cable [# 1 below] and the (-) ground cables [# 2].
•
Make sure this conduit is suitable for automotive purposes, and its class is adapted to possible sources of heat nearby. In case of
doubt, contact your national DHOLLANDIA distributor. See page 4 for contact info.
•
Fasten all connections at both ends of the cables thoroughly. Loose connections can lead to bad contacts and overheating, followed
by premature failing of the electrical circuit.
•
Apply a thick layer of dielectric grease to the electric connections to the main fuse and the batteries.
•
When mounting electrical cables, ALWAYS make sure they make a downward curve as they exit the control box or power pack; so
that water can drop off in a natural way. This is an easy way to prevent water ingress through the grommets or cable gland.
NOTICE
•
To ensure the reliability of the lift over many years, it is extremely important that the batteries, their charging system, the battery-
and ground cables, and fuses are dimensioned sufficiently strong, and fitted with care following above mentioned instructions.
Insufficient battery tension will cause harm and irreparable damage to the electric components of the lift (motor relay, electric
motor, electric switches, etc...).
•
Many vehicle manufacturers issue specific instructions where to connect the (+) battery cable and (-) ground cable, what fuses to
use etc. Make sure you observe these instructions when installing liftgates. If such prescriptions conflict with the fitting instructions
of DHOLLANDIA, contact the vehicle importer or DHOLLANDIA for further advice.
•
When installing cables, make sure these cannot be cut, squeezed, chafed, heated and melted, or damaged otherwise by the
equipment mounted on the vehicle or by the moving parts of the liftgate.
•
ALWAYS make sure that cables do NOT interfere with the vehicle suspension, the brake and hydraulic circuits or wire looms of
the vehicle. Make sure cables are mounted sufficiently far from the exhaust pipe and other heat radiating parts.
