Electrical installation

• 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 UPS must be used.
