Presetting of OVP trip points in series operation
When carrying out series operation, OVP (overvoltage protection)
trip points should be preset for both the master unit and for all slave
units.
In series operation, the OVP trip points for slave units should be set to
slightly higher values than that used for the master unit.
If the OVP trip points for the slave units are preset to a value below
that of the master unit, their overvoltage protection will function
fi rst,
turning off output from the slaves but not from the master unit.
Connection and setup procedure
1. Turn off the OUTPUT switch of each unit.
2. Turn off the POWER switch of each unit.
3. Determine the master unit.
• If the PAN-A and PAN series are used together, assign the
PAN-A series power supply as the master unit.
4. Preset the OVP (overvoltage protection) trip points for the
master and slave units.
• Preset the OVP trip points for the slave units to a value
slightly higher than that used for the master unit.
5. Set the control switch S1 of the master unit and slave units
to the positions shown in Fig.4-21.
