MOUNTING THE UNIT
The BCDC can be mounted in the cabin of the vehicle, along a chassis rail or
in the engine bay. Ensure that it does not become covered by a build-up of
mud or debris. If mounting in the engine bay, make sure it is positioned away
from high temperatures for best performance.
The unit will operate optimally below 55°C (130°F) with good airflow. At higher
temperatures the unit will de-rate output current up to 80°C (175°F) at which
point the unit will turn OFF.
Ensure the charger is mounted as close as possible to the battery being
charged (auxiliary battery).
The charger can be mounted in any orientation so long as the front decal is
visible. Use all 4 mounting points to fasten using zinc plated G4.6 M5 Screws.
FUSING
REDARC recommend using MIDI style bolt down fuses as they ensure
a low resistance connection. The REDARC FK40 and FK60 fuse kits are
recommended.
Blade type fuses are not recommended as they can result in a high resistance
connection which causes excess heat and may damage the fuse holder and/
or the wiring.
Self-resetting circuit breakers are not recommended as they may trip
prematurely due to the heat generated by the current flowing through the wires.
CHARGE PROFILE SELECTION
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:
ƒ To select Profile A leave the ORANGE wire disconnected. This will set the
Maximum voltage to 14.6 V.
ƒ To select Profile B connect the ORANGE wire to Common Ground. This
will set the Maximum voltage to 15.0 V.
ƒ To select Profile C connect the ORANGE wire to the RED wire (Input
source positive). This will set the Maximum voltage to 15.3 V.
ƒ To select the Li Profile connect the ORANGE wire to the GREEN wire (LED
output). This will set the charger to Lithium mode.
CAUTION
Check the manufacturer's data for your battery and ensure that
the Maximum voltage of the profile you select does not exceed the
manufacturer's recommended maximum charging voltage. If the Maximum
voltage is too high for your battery type, select another charging profile.
