WARNING: If the battery is connected with reverse polarity, the load terminals
will also have the wrong polarity. Never connect loads during this condition!
REMARK: The controller has a built-in voltage drop compensation which
automatically compensates battery wire voltage drops of up to 250 mV.
REMARK: Mind the recommendations of your battery manufacturer. We
strongly recommend connecting a fuse directly to the battery to protect
any short circuit at the battery wiring. The fuse must take the charge
controller nominal current:
CXN10: 15A, CXN20: 30A, CXN40: 50A
Connect the wires leading to the solar array with
correct polarity. To avoid any voltage on the wires,
first connect the controller, then the solar array.
Mind the recommended wire size:
