Powered Cradle Installation In High Voltage Vehicles
7.11.5 Powered Cradle Installation In High Voltage Vehicles
Warning: Voltages exceeding 60VDC are considered hazardous. For powered
cradle installations on vehicles with batteries above this voltage,
ensure the powered cradle power connector is mounted in a dry
location on the vehicle, or that the connector is insulated with an
appropriate waterproof material after installation. The connector
must also be installed out of the vehicle operator’s reach. Exposing
an accessible power connector to water or other liquids could create
a hazardous situation resulting in serious injury or death.
Installation of powered cradles in vehicles that operate above 60VDC require
special consideration.
Due to the hazardous voltages present on these vehicles, it is necessary to ensure
that the powered cradle power supply cable connector is not accessible to the
vehicle operator, and does not get exposed to water or other liquids. This can be
accomplished in one of the following ways:
• 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 a waterproof heat shrink material (see
“Extreme Wet Environments” note below for additional details).
• Wrap the connector securely with a 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
powered cradle.
7.11.5.1 Extreme Wet Environments
For extreme wet environments, or environments where it is difficult to restrict
vehicle operator access to the power connector, Psion Teklogix offers a waterproof
heat shrink kit (PN 1030022). The kit contains 3 pieces of waterproof, high shrink
ratio heat shrink tubing which can be used to encapsulate the entire connector
assembly. If using this kit, please ensure that you order sufficient material to cover
installation and service, remembering that heat shrink is one-time use, and must be
replaced if it is removed from the connector for any reason.
