Installing the Power Pre-Regulator

The pre-regulator is a DC/DC power supply and is available as an accessory. It should be used when the power source (usually the forklift truck battery) exceeds the input range of the VC8300 power supply (for example, trucks equipped with a 72 VDC battery).
It is recommended that all connections be secured with electrical tape or heat shrink to prevent contaminants from degrading the connection.
The Zebra power extension cable positive lead is red and the negative lead is black.
  1. Attach the pre-regulator cable male connector to the Zebra power extension cable which is installed on the vehicle.
  2. Connect the pre-regulator cable female connector either directly to the device's power cable, or to the power extension cable.
