Setting up the Slave Units
The output voltage and current of the slave units should be programmed to maximum value.
During parallel operation, the slave units operate as a controlled current source following the
controller unit's output current.
All slave units must be configured with the SCPI command to enable current sharing, or use
the following instructions to program front panel current share setup:

interface slave described in section 5.
Setting Over Voltage Protection (OVP)
The master unit's OVP should be programmed to the desired OVP level. The OVP of the
slave units should be programmed to a higher value than the master OVP. When the
controller unit shuts down, it will program the outputs of the slave units to zero volts. If a
slave unit shuts down, only that unit would shut down and the remaining slave units would
supply all the load current if possible.
