While the unit is in operation, connect the applicable outer contact, voltage, and resistance to the negative output of
the unit.
Note that the outer contact, voltage, and resistance must be float-mounted.
The photo-coupler, which is used to output alarms and the status of CV mode and CC mode, must be used at a current
of 5mA or lower when it is on, and at a voltage of 10V or lower when it is off.
