2.1

Qualified safety personnel

The TR4 safety switch must be installed, connected, commissioned and
serviced only by qualified safety personnel. Qualified safety personnel
are defined as persons who ...
due to their specialist training and experience have adequate knowl-
edge of the power-driven equipment to be checked
and
who have been instructed by the responsible machine operator in the
operation of the machine and the current valid safety guidelines
and
are sufficiently familiar with the applicable official health and work
safety regulations, directives and generally recognized engineering
practice (e.g. DIN standards, VDE stipulations, engineering regula-
tions from other EC member states) that they can assess the work
safety aspects of the power-driven equipment
and
have access to the operating instructions and have read them.
As a rule these are qualified safety personnel from the manufacturer of
the protective device or also persons who have been appropriately
trained at the manufacturer of the protective device, are primarily in-
volved in checking protective devices and are allocated the task by the
organization operating the protective device.

that are switched electrosensitively by actuators (transponders).
They monitor moveable guards as follows:
The dangerous state of the machine or system can only be switched
