9.7.6 Basic connection diagram
The following is a connection example (3 unit system) when performing parallel system operation.
Special instructions:
1. An alarm stoppage condition occurs simultane-
ously at all units when an alarm occurs (30X
operation), however, the RUN signal should be
opened at all converters in the interests of safety.
2. After ensuring that all converter units are ready for
operation [RDY], specify a sequence that issues a
run command to the inverter (ensure that it is the
inverter).
3. Alarms can be reset simultaneously at all units by
inputting an [RST] signal from any unit. If
switched over to a single system, only the unit to
which the [RST] signal is input is reset.
4. When using the parallel/single system switching
function, [OPT-DI] is assigned to the X1 contact
input.
When switching to a single system, input an
[OPT-DI] signal, bypass alarm circuits for other
than single operation units, and create a sequence
circuit so that a run command is input only to the
single operation unit.
