Cable sizing
Below is a table outlining the required cable size for a given cable install length.
Please refer to this table for Vehicle Input, Solar Input, Ground and Battery Output cable
thickness requirements. Always choose a wire cross sectional area equal to or greater
than what is specified below.

Cable and fuse sizes are specified by various codes and standards which depend on the type
of vehicle the Battery Charger is installed into. 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. The installer is responsible for ensuring that the correct cable and fuse
sizes are used when installing this Battery Charger.

TROUBLESHOOTING
There are no LEDs ON at all...
This indicates that there is no battery connected to the output (BROWN wire) or that battery
is not at a suitable voltage level to be charged AND the input (YELLOW/RED wire) of the
charger is not connected.
1. Check the Auxiliary battery is above 0.1V
2. Check all wiring to the charger and battery, particularly the Ground (BLACK wire).
3. Check fuses are intact and properly connected.
If the problem is still evident please contact your local Auto-Electrician.
The 'Charge Profile' LED is flashing...
This indicates that either Output or Input is not valid.
Specifically, an Auxiliary battery, at a suitable voltage level to be charged, is connected to the output of
the charger however there is currently no valid charging source OR a valid charging source is available
but the Auxiliary battery is not at a suitable voltage level to be charged or is not connected.
1. Check that the Vehicle (RED wire) and/or Solar (YELLOW wire) are electrically connected
a. The Vehicle (RED wire) should connect directly to the Vehicle battery positive terminal via an
24V Mode
adequately rated fuse
ON above OFF below
b. The Solar (YELLOW wire) should connect directly to the Solar Panel positive terminal/wire.
2. Check that the Ground (BLACK wire) is connected to the Auxiliary battery and Chassis Earth and/
26.4V 25.4V
or the Solar Panel negative terminal/wire.
24.0V 23.8V
3. Check the Auxiliary battery is above 0.1V
4. Check all wiring to the Auxiliary battery, particularly the Ground (BLACK wire).
5. Check fuses are intact and properly connected.
If the problem is still evident please see the relevant points below.
I have Solar connected but the 'Solar' LED is OFF...
This indicates that the required turn ON conditions for this source have not been met. Either the Open
Circuit Voltage at the YELLOW wire on the charger is below 9V or there is not sufficient power available
from the Solar Panel (due to poor light conditions or a faulty panel).
1. Is the sun out? No or low sunlight levels mean low power to your solar panels.
Closest
2. Check that the solar panel is not being shaded (by a tree etc.)
(BAE, B&S, AWG)
3. Check the voltage at the YELLOW wire, as close as possible to the charger, is above 9V.
4. Check all wiring to the Solar Panel, particularly the Ground (BLACK wire).
8
5. Ensure you have an unregulated solar panel.
6
Allow up to 2 minutes after any change for the unit to recognise the input.
6
The BCDC is connected to the 'Vehicle' but the Vehicle LED is OFF...
4
This indicates that the required turn ON conditions for this source have not been met OR the Solar input
is supplying the full input power requirements of the charger. With the BLUE wire left unconnected, the
voltage at the RED wire must be above 13.2V for a 12V installation or above 26.4V for a 24V installation.
With the BLUE wire connected to Ignition, Ignition must be on and the voltage at the RED wire must be
above 12.0V for a 12V installation or above 24.0V for a 24V installation.
1. Check that the vehicle is running.
2. Check the voltage on the RED wire is above the required turn ON threshold for your installation.
3. Check all wiring to the Vehicle battery, particularly the Ground (BLACK wire).
