  • Page 8: Battery Test Mode

    PRODUCT FUNCTION Battery Test Mode The unit features a battery test mode which occurs every 100 seconds. The test mode is designed to both test that the input conditions are still met and check for the presence of a battery on the output of the unit. This feature is designed to protect the vehicle battery from over discharge and protect the vehicle and wiring in the event of damage to the output connection.

  • Page 9: Charge Profile Selection (Orange Wire)

    INSTALLATION Charge Profile Selection (ORANGE Wire) The ORANGE wire is used to select the Maximum output voltage. This is achieved by connecting in the following way: To select Profile A leave the ORANGE wire disconnected. This will set the Maximum voltage to 14.6V. To select Profile B connect the ORANGE wire to Common Ground.

Selecting the wrong cable or fuse size could result in harm to the installer or user and/or damage to the Battery Charger or other equipment installed in the system.

  • Page 11: Wiring

    INSTALLATION Wiring The heavy gauge wires on the BCDC1225D and BCDC1240D unit carry peak currents of up to 35 and 50 Amps respectively, and it is important to make a good, low resistance, electrical connection that will not degrade over time. Failure to make a good, reliable contact may result in breakdown of the wire insulation and cause a short circuit, or worst case a fire.
