Electrical Connections
Note
: This system is 12V operation. Mount the main control unit at the selected
location and connect the RF coax cable from the antenna. Connect the antenna cable
to the
“Dish In” connector on the control unit.
Mount the Display controller using the screws provided and connect the Display loom
(Western Jack type connector) to both the Display controller and Data Box. The main
power supply plug (4 pin connector) can now be wired as below.
The colours are as below:
Red 12V Positive
This should be on an unswitched constant 12V DC supply as close to the battery as
possible to ensure no voltage drop. Alternatively connect to a reliable 12V supply
directly from the battery, i.e. main switchboard supply, fuse box etc.
Black 12V Neg/Earth
This should be a good ground supply to the battery or main earth connection at
switchboard.
Yellow 12V Ign/Switched
This is the Auto Shut Down circuit. It must be connected to either a switched ignition
source or Alternator D+ connection from the vehicle charging system OR if the unit is
installed in a caravan it can be connected to the stop light circuit.
The circuit only needs a momentary supply to activate the auto close operation.
Once these connections have been made the main loom containing the relay and fuse
holder can be connected to the Data Box.
To The Installer
Once the SC52 Satellite antenna installation is completed, check the operating voltage
whilst the dish is searching. Optimum operating voltage is 12.00V DC
– 14.8V DC,
minimum threshold is 10.5V DC. Any voltage lower than this can cause the Antenna
to not operate correctly.
