Electrical Connection
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly, Construction and Con-
nection chapter Ä Chapter 2.6 “AC500 (Standard)” on page 1248.
The electrical connection is carried out by using the 40 terminals of the terminal unit TU515/
TU516
Ä Chapter 1.4.3 “TU515, TU516, TU516-H and TU542 for I/O Modules” on page 153.
