3.7.2.2 Connect the solar panel
The RMC uses a 10 or 20 Watt solar panel with nominal 12 Vdc output voltage. Mount the solar panel
on a two-inch pipe, or on the top or side of a meter house.
Remove the CHARGER/EXT PWR terminal connector to wire the charger cable before connecting the
charger to the board.
IMPORTANT NOTE: Call the ABB main office number on the last page of this manual for
information about mounting the solar panel on the top or side of a building.
Exercise caution when handling the solar panel to avoid damaging it.
Do not place the solar panel where it is in shadows for any part of the day.
Mount the solar panel facing up from the horizon at a 50° angle. For northern hemispheres,
position the solar panel facing south. For southern hemispheres, position the solar panel facing
north.
Clean the solar panel on a regular basis to ensure maximum charging.
The hardware required to connect the solar panel to the RMC is:
–
One solar panel with an integrated cable
–
One solar panel mounting kit
NOTICE – Equipment damage. Always connect the battery to the BAT port before you
connect the solar panel or alternate charger cable to the RMC.
To connect the solar panel charger:
