Powered Cradle Installation - Psion Teklogix 7535 User Manual

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.
• 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.

7.11.6 Powered Cradle Installation

The powered cradle option is designed to allow the 7535/7530 to be powered by a
vehicle battery. The battery installed in the 7535/7530 is also recharged by the
vehicle battery. This option accepts DC power sources over the range 12V to 80V.
The 7535/7530 picker cradle can be ordered with the powered cradle option
installed, or it can be retrofitted later at an authorized Psion Teklogix service depot.
Service offices are listed in Appendix A: Support Services And Worldwide Offices.
The 7535/7530 charging LED (see "Charge LED" on page 48) indicates that
external power is available, and it also indicates the charging status of the internal
battery.
Warning: Applying a voltage above 90VDC or reversing polarity may result
in permanent damage to the cradle power option and will void the
product warranty.
Warning: TO AVOID ELECTRIC SHOCK when the powered cradle option
is installed, always ensure that the rear panel ground lug on the
picker cradle is connected to the vehicle chassis. Failure to do this
could result in serious injury or death.
The metal chassis of the picker cradle must be connected directly to the chassis of
the vehicle. A safety ground lug (clearly labelled on the rear of the cradle chassis) is
provided for this purpose. The grounding strap must connect from the ground stud
on the picker cradle 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.
