 5.3 POWER CONNECTION

 

5.3.1  Supply voltages in AC

 5.2 Recommendations for external mounting

  -  or electrical connections, use a cable with a 6÷10mm outer diameter and fully tighten the M18 cable gland
  -  Securely close the cover
  -  position the cable so that it forms a downward curve at the M18 output (Fig.4); in this way the condensation and/or  

    rain water will tend to drop from the curve bottom
  - place the transparent cover for protection
