8525 G2/8530 G2 Installation In High Voltage Vehicles
• Keep the cables away from control pedals and other moving parts that
may pull on the cables or interfere with the operation of the vehicle.
• Leave enough slack on the cables so that the computer can be removed
easily for maintenance.
Note: Make sure the cables run inside the roll cage of the vehicle.
6.3.6 8525 G2/8530 G2 Installation In High Voltage Vehicles
Warning: Voltages exceeding 60VDC are considered hazardous. For
8525 G2/8530 G2 installations on vehicles with batteries above
this voltage, ensure the 8525 G2/8530 G2 power connector is
mounted in a secure location out of the vehicle operator’s reach.
Due to the hazardous voltages present on these vehicles, it is necessary to ensure
that the unit’s power supply cable connector is not accessible to the vehicle operator,
and is not exposed to water or other liquids. To accomplish this:
• Ensure the power connector is installed in a dry location on the vehicle,
away from the vehicle operator’s reach (perhaps under a vehicle dash or in a
sealed housing).
• Cover the power connector with waterproof heat shrink material.
• Wrap the connector securely with waterproof electrical tape in an area out
of the vehicle operators reach.
All other installation requirements outlined in this document should also be
followed for High Voltage vehicles to insure safe installation and operation of the
8525 G2/8530 G2 vehicle-mount.
6.3.7 8525 G2/8530 G2 Installation In Vehicles
Note: The metal chassis of the 8525 G2/8530 G2 is equipped with a ground lug
(located on the underside of the 8525 G2/8530 G2, beside the cable man-
agement bar) to provide an additional ground to the vehicle, if desired.
The grounding strap must connect from the ground stud on the vehicle-
mount to a solid, reliable contact point on the main portion of the vehicle
chassis. It must not be connected to battery negative or a terminal block.
As with other vehicle cables, the routing of the ground strap should be carefully
considered to ensure it does not pose a hazard to the operator or the safe operation of
the vehicle. If necessary, secure the ground strap with cable ties or some other
mechanical means to prevent loops or loose lengths of wire from catching on
stationary items when the vehicle is in motion.
