Display
Only the master unit will display the
current.
Master and slave units display the voltage.
The total voltage is the sum of the units.
OVP/OCP
The master unit can shut down the slave
unit when OVP/OCP is tripped on the
master unit (if the slave connector is wired
for shut down on alarm).
OVP and OCP level is determined by the
master OVP and OCP level. The OVP and
OCP level on the slave unit is ignored.
