7.1 Prerequisites

• The signal cable must not be placed parallel to the motor cable or other power cables.
• The supply voltage used for the ELMON inducti ve 71-752 must comply with the requirements for safety
low voltage (SELV).
• Cables installed outdoors or outside of the switching cabinet must be protected appropriately.
• The protecti on class specifi ed for this device is only ensured if the supply lines have been properly clamped
to the screw connecti ons.

7.2 Supply voltage

With the ELMON inducti ve 71-752, +24 V DC / GND is to be connected to
8 terminal pairs 5, 6 as voltage supply. The supply line to the switching
9
10
unit must be protected with an appropriate fuse.
7.3 onnecti ng the stati onary coil core
Connect the stati onary coil core to terminal pair 1, 2; no special att enti on
is required for polarity.
7.4 Connecti ng the stati onary safety contact edges
8
9
10
The stati onary safety contact edge(s) on the leading pillar for the opening
movement is (are) connected to terminal pair 3, 6.
If several safety contact edges are being used, they must be connected
in series and the end edge must be terminated using an 8.2 kΩ resistor.
The stati onary safety contact edge(s) for the closing movement is (are)
connected to terminal pair 4, 6.
If one or both channels for the stati onary safety contact edge are not
9
10
used, the supplied 8.2 kΩ resistors are to be connected to the respec-
ti ve channels.
7.5 Connecti ng the control circuits
The control circuit to be monitored for the opening movement (stop-
opening movement) is to be connected to terminal pair 9, 10 ; for the
closing movement (stop-closing movement), the appropriate control
8 circuit is to be connected to terminal pair 7, 8. The control circuits are
9
10
dependent on the rated current to protect with an appropriate fuse or the
rated current to the control circuits must be limited by other measures
to the maximum value.
