7.3 Connecting the interfaces
All interfaces are located on the connection circuit board behind the cover for the connection area. Use the cable
fittings and plug connections provided (see Figure 13 on page 24).
DANGER
Risk of fatal injury due to electric shock
Severe injury or death from improper use of the interface connections and non-observance of
protection class III.
› The SELV circuits (SELV: safety extra low voltage) can only be connected to other SELV circuits with
protection class III.
7.3.1 Determining the inverter version
Check with connection cover open, whether there are on the front of the display board 2 DIP switches on the left
side of the RS485 connectors:
NOTE
When routing the interface connection cable, note that too little clearance to the DC or AC cables can
cause interference during data transfer.
