Safety Relay
8. Electrical connecti on

8.1 Prerequisites

The signal cable must not be placed parallel to the motor cable or other power cables.
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.
Connecti ng to the wrong terminals can destroy the switching unit.
The limit values for the supply voltage and the switching capacity of the relay specifi ed in the „technical
specifi cati ons" are to be observed.
Suffi cient fuse protecti on must be provided on all output contacts with capaciti ve and
inducti ve loads.

8.2 Supply voltage

The 230 V supply voltage must be connected to terminals L1 and N. Connect 24 V supply voltage to terminals
24 V AC/DC .
8.3 Connecti ng the sensor
18
For the voltage supply, either mains voltage (230 V AC 50/60 Hz) or low
voltage (24 V AC/DC) may be used.
When supplying with 24 V AC/DC, the voltage must comply with the require-
ments for Safety Low Voltage (SELV). The supply line to the switching unit
must be protected with an appropriate fuse.
Never apply both voltages simultaneously!
Connect the sensor for channel 1 to terminal pair STATIONARY Opening. Connect
the sensor for channel 2 to terminal pair STATIONARY Closing .
If a channel is not used, it must be connected to an 8.2 kΩ resistor.
