Connecting the PROFINET cable to the inverter

Procedure
1. Integrate the inverter in the bus system (e.g. ring topology) of the control using PROFINET
cables and the two PROFINET sockets X150-P1 and X150-P2.
The maximum permitted cable length from the previous station and to the next one is 100 m.
2. Externally supply the inverter with 24 VDC through terminals 31 and 32.
The external 24 V supply is only required if communications with the control should also
run when the line voltage is switched off.
You have now connected the inverter to the control system via PROFINET DP.
❒
Communication with the controller even when the supply voltage on the Power Module is
switched off
You must supply the Control Unit with 24 V DC at terminals 31 and 32 if you wish to maintain
communication with the control system when the line voltage is switched off.
In the case of brief interruptions of the 24 V power supply, the inverter may signal a fault without
communications with the control system being interrupted.
