Appendix
Safety precautions
Safety switches perform a personal protection function. Incorrect
installation or tampering can lead to severe injuries to personnel.
Prior to installation, use and maintenance, it is imperative that you read
the operating instructions. Also take into account the following points:
Notes on installation
Position switches with safety function
Safety switches with separate actuator
Safety switches must not be bypassed (bridging of contacts), turned
away, removed or otherwise rendered ineffective.
The switching operation on safety switches with separate actuator
must only be triggered by actuators specifically provided for this
purpose which are permanently connected to the safety guard.
Mounting and electrical connection must be performed only by
authorized personnel.
Safety switches and actuators must not be used as an end stop.
Switching elements are not allowed to be replaced on safety
switches.
Series NZ..VZ..VS and TZ safety switches with locking solenoids
are not allowed to be used in potentially explosive atmospheres.
If damaged or worn, safety switches must be replaced as a unit.
To obtain the direct opening travel according to IEC 60947-5-1, the
trip dog setting distance shown in the dimension 52 (+1) must be
observed (see technical data, travel diagrams). Actuation elements
such as cam approach guides must be positively mounted in
accordance with EN 1088, i.e. riveted, welded or otherwise secured
against becoming loose.
Safety switches must not be used as an end stop.
It must be ensured that the safety switch does not move after
adjustment.
It must be possible to replace safety switches without the need for
re-adjustment.
The safety switch and actuator must be installed properly. The
actuator must be positively mounted, e.g. by using safety screws
(are included with the actuator) or by welding, riveting, or pinning.
Safety switches must not be used as an end stop.
Safety switches must be mounted such that they can be replaced.
A hazard analysis must be prepared as per the Machinery directive.
The hazardous point must be classified with the aid of type C standards
or EN 954-1 or its successor. Safety switches must be chosen to
match this classification and the information given in DIN EN 1088.
