6.1
General requirements
The following measures to prevent common-cause failures must be considered during
electrical installation:
•
Separation of the signal pathways for the safety system signals, e.g. by laying sep‐
arate cables or shielding the signal paths separately.
•
Protection against overvoltage, overcurrent, etc. according to the manufacturer’s
instructions for the individual components.
•
Mechanical fastening of the wiring of the pushbutton for the manual muting
device, e.g. with cable ties.
•
Measures for controlling the consequences of voltage failure, voltage fluctuations,
overvoltage and undervoltage in the voltage supply of the process controller.
