Controller’s load terminals can be connected to DC electric equipments whose nominal
operation voltage is the same as nominal voltage of battery. The controller supplies power
to loads with battery voltage.
It is suggested that positive pole or negative pole of battery and loads be connected to a
safety device whose operation current is not twice lower than nominal charging or
discharging current. Do not switch on the safety device while it is being installed. Switch
on the safety device after the wiring is confirmed.
CAUTION: On occasions that controller must be connected to the
ground. For common positive controller, the positive pole must be
connected to the ground, on the contrary, the negative pole must
be connected to the ground for common negative controller.
