Ensure line protection by triggering the fuse!
a) The supply voltage must be able to supply fourfold of the rated current of the
internal fuse (4 A).
b) If a smaller power supply is used depending on the application, the device must
be protected with an external fuse.
• Lay control and power cables separately (approx. 10...20 cm distance).
• Lay power cable crossings at right angles.
• The following measures can be taken to prevent electromagnetic interferences:
– Always connect the shielding with the greatest possible surface.
– Position the shield as close as possible to the terminal.
– Always use twisted and shielded cables for analog control cables. Connect
shielding to source on one side only.
– Twist digital control cables. Shielding may be required from 3 m. In this
case, place on both sides.
• The device is protected against reverse polarity of the input voltage.
• The 24 V supply must not fall below or exceed the input voltage range specified
in the technical data, independent of the operating conditions.
• If power interruptions need to be bridged, an external

Malfunctions due to loose contacts.
a) Observe metal sleeve length and stripping length according to table.
b) Use a suitable pressing tool.
c) Make sure that all wires are inserted into the wire-end sleeve.
d) After inserting the cable into the terminal, check that it is firmly seated.
