7. Connecting the device
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 INDUS rail 71-242 and the INDUS rail 71-942 must comply with the
requirements for safety low voltage (SELV).
• Cables installed outdoors or outside of the switching cabinet must be protected appropriately.
•
The protection class specified for this device is only ensured if the supply lines have been properly clamped
to the screw connections.

Supply voltage
With the INDUS rail 71-242 and INDUS rail 71-942, 24 V AC/DC is to be
connected to terminal pair
8, 9
as voltage supply. The supply line to the
switching unit must be protected with an appropriate fuse.
7.3 Connecting the stationary coil core
INDUS rail 71-242:
Connect the stationary coil core to terminal pair
1, 2
;
no special attention is required for polarity.
INDUS rail 71-942:
The stationary coil core is to be connected to the
Transmit
slot.
7.4 Connecting the stationary safety contact edges
INDUS rail 71-242:
The stationary safety contact edge(s) on the leading
pillar for the opening movement is (are) connected to terminal pair
3, 11
.
INDUS rail 71-942:
The stationary safety contact edge(s)
for the opening
movement is (are) connected to the
Stationary Opening
slot.
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.
INDUS rail 71-242:
The stationary safety contact edge(s) for the closing
movement is (are) connected to terminal pair
3, 10
.
INDUS rail 71-942:
The stationary safety contact edge(s) for the closing
movement
is (are
) connected to the
Stationary Closing
slot.
If one or both channels for the stationary safety contact edge
are not
used, the supplied 8.2 kΩ resistors are to be connected to the respec
-
tive channels.
