7.1 Prerequisites

.1 Prerequisites Prerequisites
• The suppl�� voltage used �or the ISK 71‑242 and the ISK 71‑942 must compl�� with the requirements �or
sa�et�� low voltage (SELV).
• Cables installed outdoors or outside o� the switching cabinet must be protected appropriatel��.
• The protection class specified �or this device is onl�� ensured i� the suppl�� lines have been properl�� clamped
to the screw connections.

7.2 Supply voltage .2 Supply voltage
With the ISK 71‑242 and ISK 71‑942, 24 V AC/DC is to be connected to
terminal pair 8, 9 as voltage suppl��. The suppl�� line to the switching unit
must be protected with an appropriate �use.
7.3 Connecting the stationary coil core
ISK 71-242: Connect the stationar�� coil core to terminal pair 1, 2; no special
attention is required �or polarit��.
ISK 71-942: The stationar�� coil core is to be connected to the Transmit

slot.
The cable �or the coil core is connected using the supplied crimp connec-
tors or b�� directl�� soldering the wire to the connectors.

7.4 Connecting the stationary contact edges

ISK 71-242: The stationar�� sa�et�� contact edge(s) (SCE) on the leading pillar
�or the opening movement is (are) connected to terminal pair 3, 11 .
ISK 71-942: The stationar�� SCE(s) �or the opening movement is (are)
connected to the Stationary Opening slot .
I� several SCEs are being used, the�� must be connected in series and the
end edge must be terminated using an 8.2 kΩ resistor.
ISK 71-242: The stationar�� SCE(s) �or the closing movement is (are) con-
nected to terminal pair 3, 10 .
ISK 71-942: The stationar�� SCE(s) �or the closing movement is (are) connected
to the Stationary Closing slot.
If one or both channels for the stationary SCE are not used, the sup-
plied 8.2 kΩ resistors are to be connected to the respective channels.
