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.
