CABLE SIZING
The table outlines the required cable size for a given cable install length.
Please refer to this table for Vehicle Input (RED), Solar Input (YELLOW),
Ground (BLACK) and Battery Output (BROWN) cable thickness requirements.
Always choose a wire cross sectional area equal to or greater than what is
specified below.

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 0.1 V.
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:
ƒ The Vehicle (RED wire) should connect directly to the Vehicle battery
positive terminal via an adequately rated fuse.
ƒ 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/or the Solar Panel negative terminal/wire.
3. Check the Auxiliary battery is above 0.1 V.
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 see the relevant points below.

CAUTION
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
Size
cable and fuse sizes are used when installing this Battery Charger.

If using an Optional LED, use a standard 12 V LED with an integrated resistor
(12 V = 1kΩ or 24 V = 2.2kΩ). A basic 3 V LED will not operate correctly if installed.
Solar is 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 9 V 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.
2. Check that the solar panel is not being shaded (e.g. by a tree).
3. Check the voltage at the YELLOW wire, as close as possible to the charger,
is above 9 V.
4. Check all wiring to the Solar Panel, particularly the Ground (BLACK wire).
5. Ensure you have an unregulated solar panel.
Allow up to 2 minutes after any change for the unit to recognise the input.
The BCDC is connected to the 'Vehicle' but the Vehicle
LED is OFF
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 12.9 V for a 12 V installation or above 25.8 V for a 24 V
installation. With the BLUE wire connected to Ignition, Ignition must be on
and the voltage at the RED wire must be above 12.0 V for a 12 V installation or
above 24.0 V for a 24 V 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).
