(3). Connect the Auxiliary Battery negative (-) terminal to the SVDC1225 / SVDC
1250 Common Ground cable (black colour). Alternatively connect both Auxiliary
Battery negative (-) terminals and SVDC1225 / SVDC1250 Common Ground
cable to vehicle chassis ground.
(4). Connect the Starter Battery positive (+) terminal to the SVDC1225 / SVDC
1250 Alternator Input cable (red colour). Fit a 50A /100A fuse to the cable as
close as possible to the Starter Battery positive (+) terminal.
(5). If your vehicle has fixed voltage or temperature compensating alternator
installed, leave the Ignition Override cable (blue colour) open.
If your vehicle has smart (variable voltage) alternator installed, the Ignition
Override cable must be connected to the vehicle's ignition. The SVDC1225 /
SVDC1250 will only operate when the vehicle's ignition is turned on.
However, if solar panels are connected to SVDC1225 / SVDC1250, the charger
will operate and only draw power from solar panels (assuming vehicle's ignition
is turned off).
Fit a 1-2A fuse to the cable as close as possible to the vehicle's ignition.
Consult the vehicle manufacturer for type of alternator installed in your vehicle.
(6). When 12V solar panels are present, connect the solar panel positive
terminal (+)to the SVDC1225 / SVDC1250 Solar Input cable (green colour).
Fit a 50A /100A fuse to the cable as close as possible to the Solar Panel
positive (+) terminal.
Then, connect the Solar Panel negative (-) terminal to the SVDC1225 / SVDC
1250 Common Ground cable (black colour). Alternatively connect both Solar
Panel negative (-) terminals and SVDC1225 / SVDC1250 Common Ground
cable to vehicle chassis ground.
(7). The external LED wire provides 4mA constant current output. It can power
an LED panel mount indicator with or without an internal resistor.
Leave External LED cable open if you do not need the external LED indication.
If external LED indication is required, connect the positive (+) terminal of a
LED Indicator to the External LED cable.
Then, connect the negative terminal of LED Indicator to the vehicle chassis
ground.
