Remote Interlock Connection on the Supply Unit
The remote interlock jack is located on the rear side of the supply unit (12 V DC operating
voltage, Figure 16).
The remote interlock plug, which contains a shorting bridge, is connected to this jack.
Remote interlock devices such as those connected to the room, the door or other onsite
safety interlock systems can also be connected to the remote interlock connector. The laser
beam path is interrupted if the contact is open.
The overall length of the cable between the two connecting pins of the remote interlock
connector must not exceed 10 m.
