INSTALLATION DIAGRAM
Power Lines
The DCC has the power flow from Connector A to Connector B.
Basically, there are two kinds of connections possible of the DCC-0850 for use in leisure vehicles:
3-wires and 4-wires connection. The latter is highly recommended!
3-Wire connection
The 3-wire connection is more simple, in that, only one output is used both for the Service Battery
and for the motorhome loads.
This type of cabling does not allow the unit the current delivered to the load to that delivered to
the battery, making optimal battery charging quite difficult.
