Mounting the Terminal Blocks

Connection The I/O periphery and the voltage supply of the branch interface module are

connected using an 8 pin terminal block.

Selection of

terminal types

Two different types of terminal can be chosen according to its usage.

These are available as a set of 3, see Overview of Ordering Information, p. 50:

Use of coding

pins

The module can be used in dangerous and safe voltage ranges. Dangerous

voltages are higher than 42.4 VAC or 60 VDC.

A set of plastic coding pins is supplied with the terminal block. Correct usage of

these coding pins will prevent insertion of terminal blocks that are wired for other

voltages.
