2. Special versions
   For special versions, which are not listed in the ordering code, these specifications apply accordingly, provided that they correspond to the standard version.

3. Purpose
   The safety switches with separate actuator are suitable for sliding, hinged and removable safety guards, which need to be closed in order to ensure the necessary operational safety.
   The safety switches are used for applications, in which the hazardous situation is terminated without delay 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.

4. Warning about misuse
   In case of improper use or manipulation of the safety switchgear, personal hazards or damages to machinery or plant components cannot be excluded. There are no residual risks, provided that the safety instructions as well as the instructions regarding mounting, commissioning, operation and maintenance are observed.

5. Exclusion of liability
   We shall accept no liability for damages and malfunctions resulting from defective mounting or failure to comply with the operating instructions manual. The manufacturer shall accept no liability for damages resulting from the use of unauthorized spare parts or accessories.
   For safety reasons, invasive work on the device as well as arbitrary repairs, conversions and modifications to the device are strictly forbidden, the manufacturer shall accept no liability for damages resulting from such invasive work, arbitrary repairs, conversions and/or modifications to the device.

   If multiple safety components are wired in series, the Performance Level to EN ISO 13849-1 will be reduced due to the restricted error detection under certain circumstances.

Mounting

1. General mounting instructions
   Please observe the remarks of the standards EN ISO 12100, EN ISO 14119 and EN ISO 14120
   The mounting position however must be chosen so that the ingress of dirt and soiling in the used opening is avoided.
   Use the supplied base plate for the fixing. The tightening torque of the fixing screws must not exceed 150 Ncm. The enclosure must not be used as an end stop. Any position is possible. The mounting position however must be chosen so that the ingress of dirt and soiling in the used opening is avoided. The unused opening must be sealed by means of slot sealing plugs.

2. Dimensions] All measurements in mm.
   
   

3. Mounting of the actuator
   See operating instructions Actuator.
   The actuator must be permanently fitted to the safety guards and protected against displacement by suitable measures (tamperproof screws, gluing, drilling of the screw heads).

Electrical connection

1. General information for electrical connection
   The electrical connection may only be carried out by authorised personnel in a de-energised condition.
   IDC method of termination
   The IDC method of termination (cut clamp technology) enables connecting flexible wires with cable section 0.75 … 1 mm² without using conductor ferrules. To this effect, strip the wire for 17 … 20 mm and insert it into the cable gland, close the cable gland, push the conductors in the groove of the cover (refer to wiring example) and screw the cover back. Alternatingly tighten the cover screws uniformly. Tightening force for the Torx T10 cover screws 0.7 … 1 Nm.

Set-up and maintenance

The safety function of the safety components must be tested. In the case of correct installation and adequate use, the safety switchgear features maintenance-free functionality. A regular visual inspection and functional test, including the following steps, is recommended:

1. Check for correct installation of the actuator and the switch
2. Check the integrity of the cable entry and connections
3. Check the switch enclosure for damages
4. Remove particles of dust and soiling

Adequate measures must be taken to ensure protection against tampering either to prevent tampering of the safety guard, for instance by means of replacement actuators.
****Damaged or defective components must be replaced.

Disassembly and disposal

1. Disassembly
   The safety switchgear must be disassembled in a de-energised condition only.

2. Disposal
   The safety switchgear must be disposed of in an appropriate manner in accordance with the national prescriptions and legislations.
