Installation
Before assembling, disassembling or wiring the module, put the entire system in a safe,
voltage-free condition. The module must be mounted in a control cabinet or terminal box
for operation.
General Instructions for Operating the Safety Modules
In the Safety System handbook, the following topics to be observed are covered:
•
System requirements
•
Performance level e according to EN ISO 13849 and/or SIL 3 according to EN

•
Safety guidelines

Function and operation
To power the Safety modules correctly, the C-DIAS bus must be used (see below). The
construction and structure are shown in the following illustration.
The appropriate module carriers for the C-DIAS bus are, for example, CMB 021/041/081
with 2, 4 or 8 slots for C-DIAS modules respectively. Important is that the connector slot
framed in red shown in the picture is intended for a PLC or coupler module.
A C-DIAS IPC (Compact DIAS Industrial PC) is typically used as the PLC, while for exam-
ple, a CIV 512 can be used as the coupler module. In the latter however, a connection to a
PLC over the VARAN bus is required.
