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.
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
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 digital outputs!
Reason: Externally voltages at an output or several outputs may cause that
other outputs are supplied through that voltage instead of voltage UP3 (reverse
voltage). This ist not intended usage.
CAUTION!
Risk of malfunction by not intended usage!
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 conncted at the outputs
DO0...DO7.
