device according to EN ISO 14 119:2003, section 7.
Liability is excluded in the following cases:

Validate the overall system!
You are responsible for the safe integration of the device in a safe over-
all system. For this purpose the overall system must be validated, e.g.
in accordance with EN ISO 13 849J2.

At work, always act in an environmentally responsible manner.
