electronically controlled and is bi-stable, i.e. it retains its position (unlocked/locked) in the event of a power failure.

Connection is made to an 8-pole M12 connector, where dual signals for locking/unlocking are used for safe

operation, i.e. no dangerous situation will occur because of short-circuits or cable breakage.

Knox, with frame part Knox 2X, is a process lock with a built in safety sensor to monitor that door is closed and

locked. While powered, a single locking signal must be applied to keep the device locked. However, the locking

function is bi-stable in case of a power failure, i.e. the lock retains its position (unlocked/locked) if power to the

Shielded cable is recommended between this unit and the rest of the safety circuit.

Carefully read through this entire manual before using the device.

The devices shall be installed by a trained electrician following the Safety regulations, standards and the Machine

directive.

Failure to comply with instructions, operation that is not in accordance with the use prescribed in these instructions,

improper installation or handling of the device can affect the safety of people and the plant.

For installation and prescribed use of the product, the special notes in the instructions must be carefully observed

and the technical standards relevant to the application must be considered.
