Mounting, Dimensions And Electrical Connection - ABB AC500-S Safety User Manual

The terminals 1.8 to 4.8 and 1.9 to 4.9 are electrically interconnected within the I/O Terminal Unit and have
always the same assignment, independent of the inserted module:
n Terminals 1.8 to 4.8: Process voltage UP = +24 V DC
n Terminals 1.9 to 4.9: Process voltage ZP = 0 V
The assignment of the other terminals is dependent on the inserted expansion module (see the description
of used expansion modules).

3.6.2 Mounting, dimensions and electrical connection

The Safety I/O modules can be plugged only on spring-type TU582-S I/O Terminal Unit. The unique mechan-
ical coding on I/O Terminal Units prevents a potential mistake of placing the Non-safety I/O module on Safety
I/O Terminal Unit and the other way around.
Installation and maintenance have to be performed according to the technical rules, codes and relevant
standards, e.g. EN 60204 part 1, by skilled electricians only.
