Setting the PROFIBUS DP address via DIP switches
The PROFIBUS DP address can be set via DIP switch, as shown in the table below.
Table 4-1

Add to address
Example 1: Address = 3 = 1 + 2
Example 2: Address = 88 = 8 + 16 + 64

Connecting the PROFIBUS DP

Connecting the Inverter to the PROFIBUS DP network
The inverter is to be connected to the PROFIBUS DP network via a sub-D socket on the
CU240S DP or CU240S DP-F. The pins of the socket are short-circuit-proof and isolated.
Table 4-2
External 24 V supply
If the PROFIBUS DP interface is required to communicate with the Control Unit when the
Power Module mains power is not present, a 24 V supply must be connected to the Control
Unit terminals 31 (+ 24 V I
