on page 149. Properly position the module and press until it locks in place.
The electrical connection of the I/O channels is established 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, 3.8, 2.9, 3.9 and 4.9 are electrically interconnected within the terminal unit
and always have the same assignment, irrespective 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
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

Chapter 2.6 “AC500 (Standard)” on page 1248.
With a separate UP3 power supply, the digital outputs can be switched off exter-
nally. This way, an emergency-off functionality can be realized.
Do not connect any voltages externally to the digital outputs!
Reason: External voltages at an output or several outputs may cause other out-
puts to be supplied via that voltage instead of voltage UP3 (reverse voltage).
This ist not the intended use.
CAUTION!
Risk of malfunctions by unintended use!
If the function cut off of the digital outputs should be used by deactivation of the
supply voltage UP3, be sure that no external voltage is connected at the outputs
DO0..DO7 and DC0..DC7.
