Connecting parallel operation
A
NOTICE!
• Use a cable with a cross section of 0.25 – 0.75 mm² for connecting
to the terminals for parallel operation.
• Parallel operation can only be set up using the same models (same
item number).
• A maximum of three inverters can be operated in parallel.
• The inverters operating in parallel must have the same settings for
mains voltage and mains frequency. (see chapter "Configuring the
inverter" on page 24.
➤ Set the main switch (fig. 5 3, page 4) to "OFF".
➤ Connect the inverter according to the sample circuit diagram (fig. b, page 7).
In particular, make sure that the bridges for parallel operation are set correctly:
• Bridge removed (fig. b 1, page 7) for inverter A and set for inverter B and C.
I
NOTE
The first inverter which is switched on after installing parallel operation is
the master.
