Purpose
The safety switches with separate actuator are suitable for sliding,
hinged, and removable safety guards, which need to be closed to ensure the
necessary operational safety. They are used for applications in which the
hazardous situation is terminated immediately when the safety guard is opened.
When the safety guard is opened, the NC contacts are positively opened, and
the NO contacts are closed. The safety switchgears are classified according to
EN ISO 14119 as type 2 interlocking devices. The user must evaluate and design
the safety chain in accordance with the relevant standards and the required
safety level. The entire concept of the control system, in which the safety
component is integrated, must be validated to the relevant standards.
Warning about misuse
In case of improper use or manipulation of the safety switchgear, personal
hazards or damage to machinery or plant components cannot be excluded. There
are no residual risks, provided that the safety instructions and the
instructions regarding mounting, commissioning, operation, and maintenance are
observed.

The mounting dimensions are indicated on the rear of the component. The enclosure must not be used as an end stop. Any mounting position. The mounting position however must be chosen so that the ingress of dirt and soiling in the used opening is avoided. The unused openings must be sealed by means of slot sealing plugs (AZ 15/16 – 1476-1 available as accessory) after fitting.
