unit is mounted on a DIN rail or with 2 screws plus the additional accessory for wall mounting
(TA526

Chapter 1.8.2.4 “TA526 - Wall Mounting Accessory” on page 1152).
The electrical connection of the I/O channels is carried out using the 30 terminals of the I/O ter-
minal unit. I/O modules can be replaced without re-wiring the terminal units.
The terminals 2.8 and 3.8 as well as 2.9, 3.9 and 4.9 are electrically interconnected within the
terminal unit and have always the same assignment, independent of the inserted module:
Terminals 2.8 and 3.8: Process supply voltage UP = +24 VDC
Terminal 4.8: Process supply voltage UP3 = +24 VDC
Terminals 2.9, 3.9 and 4.9: Process supply voltage ZP = 0 V
With a separate UP3 power supply, the digital outputs can be switched off exter-
nally. This way, an emergency-off functionality can be realized.
