For information about wiring specifications see Ä Chapter 2.6.4.3 “Terminals at
the Terminal Unit” on page 1274.
For a detailed description of the mounting, disassembly and electrical connec-
tion of the terminal units and the I/O modules, please refer to the "System
Assembly, Construction and Connection" chapter Ä Chapter 2.6.3 “Mounting
and Demounting” on page 1261.
The terminals 1.8 and 2.8 as well as 1.9, 2.9 and 3.9 are electrically interconnected within the
terminal unit and have always the same assignment, independent of the inserted module:
Terminals 1.8 and 2.8: Process supply voltage UP = +24 VDC
Terminal 3.8: Process supply voltage UP3 = +24 VDC
Terminals 1.9, 2.9 and 3.9: Process supply voltage ZP = 0 V
The assignment of the other terminals is dependent on the inserted communication interface
module.
