6.1.3 Signal Return bus at parallel operation
The Signal Return of each paralleled unit can be connected together to form a common Signal Return bus.
By this way, the control and monitoring signals of the paralleled units can be connected to the same control and
monitoring circuitry.
The Signal Return bus can be connected to the -V or -S or +V or -S or float. Fig 6-3 shows typical connection of
the Signal Return at parallel operation.
6.1.4 Remote On/Off control at parallel operation
The paralleled units can be turned On or Off via a single On/Off control. Refer to Fig 6-4 for typical application. The
Signal Return function of all the paralleled units should be connected together to create a common Signal Return
bus. The Signal Return bus may be connected to the -V or the +V potential or floated. In any case do not connect
the Signal Return bus to different potentials.
