Unit description
The safety relay meets the requirements of EN 60204-1 and IEC 602041 and may be used in applications with
` E-STOP pushbuttons
` Safety gates
The max. category the safety contacts
can achieve in accordance with EN
954-1 is stated in the technical details.
Safety features
The relay conforms to the following
safety criteria:
` The circuit is redundant with built-in
self-monitoring.
` The safety function remains effecti-
ve in the case of a component failure.
` The correct opening and closing of
the safety function relays is tested
automatically in each on-off cycle.
` The unit has an electronic fuse.

Terminal configuration
Installation
` The safety relay should be installed
in a control cabinet with a protection type of at least IP54.
` Use the notch on the rear of the unit
to attach it to a DIN rail.
` Ensure the unit is mounted securely
on a vertical DIN rail (35 mm) by
using a fixing element (e.g. retaining
bracket or an end angle).
