Protective measures

Plastic version

Protective measures are met automatically when the actuators and lens assemblies are mounted on metal front plates and enclosures.

When mounted in insulated enclosures, the "total insulation" safety requirements are met.

Grounding is necessary for operation with protective extra-low voltage (PELV).
