5.4 Step 2: Connecting signal cables

Note
Use cables with a cross section of at least 1.5 mm
power supply.
Wiring guidelines
1. Release the catch on the lid of the terminal box using a 3 mm Allen key.
2. Unscrew the lid of the terminal box.
3. Push the supply cable through the cable glands up to the terminal strip. Lay the cable in a loop
before the cable glands so that moisture does not get inside the terminal box.
4. Connect the cables according to the figure below.

Step 2: Connecting signal cables
Lay the signal cables separately from cables with voltages > 60 V.
Avoid laying signal cables close to large electrical installations or use - if possible - only shielded
cables.
Note
In a wet environment, the signal cable for digital output 2 (terminals 3 and 4) must be isolated
when the feed-in voltage is more than 16 V AC/35 V DC (16 V RMS/ 22.6 V peak).
Only use signal cables with twisted wire pairs.
