Powered Cradle Installation In High Voltage Vehicles
6.11.5 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.
• 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.
6.11.6 Powered Cradle Installation
The powered cradle option is designed to allow the 7530 G2 to be powered by a
vehicle battery. The battery installed in the 7530 G2 is also recharged by the vehicle
battery. This option accepts DC power sources over the range 12V to 80V.
The 7530 G2 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 7530 G2 charging LED (see “Charge LED” on page 43) indicates that external
power is available, and it also indicates the charging status of the internal battery.
