OVP (overvoltage protection) setting
OVP (overvoltage protection) is set on both master and slave units
according to "3.2.2 Setting the OVP (Overvoltage Protection) Trip
Point".
However, set the OVP trip point of the slave unit slightly higher than
that of the master unit, so that the OVP function of the master unit is
activated first. Set the trip point before specifying units to operate in
slave mode through CONFIG settings.
OCP (overcurrent protection) setting
OCP (overcurrent protection) is set on both master and slave units
according to "3.2.3 Setting the OCP (Overcurrent Protection) Trip
Point".
Set the value equal to the current to be protected divided by the num-
ber of units connected in parallel for OCP.
Set the OCP trip point of the slave unit slightly higher than that of the
master unit, so that the OCP function of the master unit is activated
first.
5.2.5 Master-slave parallel Operation Procedure
• When turning on the POWER switch, be sure to turn on the
master unit first.
When turning off the POWER switch, be sure to turn on the
slave units first. If you don’t keep the procedure, erroneous

The switches on the slave units are disabled. OUTPUT on/off opera-
tion is performed on the master unit.
