Powered Cradle Installation In High Voltage Vehicles
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 appropri-
ate 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 fol-
lowing 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.
•
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.

to be powered by a
vehicle battery. The battery installed in the hand-held is also recharged by the vehicle
battery. This option accepts DC power sources ranging from 9 to 20V, with optional pre-
regulator.
The vehicle cradle can be ordered with the powered cradle option installed.
Applying a voltage greater than that specified or reversing or reversing polarity may result
in permanent damage to the cradle power option and will void the product warranty.
7.30.1 Wiring Vehicle Power To The Cradle
An optional 1.8 meter (6 foot) extension power cable (PN 13985) compatible with your
powered vehicle cradle can be purchased from Psion Teklogix. This optional cable should
be wired to a filtered, fused (maximum 10A) accessory supply on the vehicle. The power
