Interlock Connector on the Supply Unit
The interlock connector (plug connection for the remote-controlled safety "interlock") is on the rear
side of the supply unit. Operating voltage is 12 V DC (for the flexible supply unit see Figure 19; for
the compact supply unit see Figure 18).
The interlock connector on the supply unit has a shorting plug in its factory condition. The shorting
plug is removable in order to connect a remote-controlled safety interlock (cable and safety switch).
The laser beam path is interrupted if the contact is open. The safety interlock can, for example. be
connected to a door contact. When the door is opened, the laser beam is then interrupted
automatically.
The total length of the cable must not exceed 10 m. If a large amount of electromagnetic interference
(EMC) is expected in the environment, use a shielded cable with a shielded plug.
