RAMP INSTALLATION

Electrical Connections

An 8-pin Deutsch connector is mounted at the back of the RA300 ramp. A mating connector (male plug) is supplied with the ramp. The power supply (12 volt or 24 volt), the ground, a ramp OUT signal (+) and a ramp IN sig- nal (+) must be terminated in the supplied Deutsch connector.

The ramp installer provides an appropriate control switch for the end user. A momentary contact

ramp control switch (center off) will typically be mounted near the driver. The control switch may be part of a panel providing other features and controls (power on/ off indicators, LED’s, etc.).

WARNING

Route cables clear of exhaust system, other hot areas and moving parts. Failure to do so may result in serious bodily injury and/or property damage.

The Positive (+) “battery” lead wire must be protected by an in-line 30 ampere fuse or circuit breaker (installer pro- vided).

Do not connect the power “battery” lead wire to the battery until all other connec- tions are made.

Connect the 8-pin Deutsch male plug to the mating Deutsch connector mounted at the back of the pan.

Carefully connect the power “battery” lead wire to the Positive (+) battery post.
