Mounting InformationUse non-removable screws, bolts, or nuts to mount the switch and actuator. Do not over torque the mounting hardware.

Position the switch and actuator so they are aligned with each other.

Mount the switch and actuator to removable guard, door, or gate. Keep the switch and actuator within the sensing range below.

This switch is not meant to be fully embedded in metal. Use the stainless steel version (440N-Z21S17* or 440N-Z21U17*) for embedding.

Maintenance

Monthly

Check the correct operation of the switching circuit. Also check for signs of abuse or tampering. Inspect the switch casing for damage.

RepairIf there is any malfunction or damage, no attempts at repair should be made. The unit should be replaced before machine operation is allowed.

Declaration of ConformityThis is to declare that the products shown in this document conform with the Essential Health and Safety Requirements (EHSRs) of the European Machinery Directive. These products also conform to EN 60947-5-3, EN ISO 14119, and have Third Party Approval.

For a comprehensive certificate please visit: www.ab.com/safety.

Check the machine is isolated and stopped whenever the interlocked guard door is open.

IMPORTANT: Afterinstallation and commissioning, the actuator, switch and switch lid fixing screws should be coated with tamper evident varnish or similar compound.
