Qualification of trained personnel
The device may only be commissioned by trained control and automation techno-
logy professionals, who are familiar with:
– installation and operation of control systems
– the applicable regulations for operating safety-engineered systems
– the applicable regulations for accident protection and occupational safety, and
– the documentation for the product.
Note
Work on safety-related systems should only be carried out by authorised spe-

Failures due to common cause (common cause failure – CCF)
Common cause failures cause the loss of the safety function, since in this case
both channels in a two-channel system fail simultaneously.
Through the following measures, you ensure that common cause failures are
avoided:
– Observe operating voltage limits
– Comply with temperature range
