6.3 CONNECTION TERMINALS VERSION “B”
1) Separate the motor or power control cables from the VLW60T connection cables
2) Remove the caps from the cable glands and open the cover by loosening the appropriate screws.
3) Insert the cables into the transmitter through the cable glands.
4) Close the cover and tighten the cable glands.
6.4 INFILTRATIONS OF HUMIDITY
To avoid moisture inltration inside the enclosure, the following are recommended:
- For the electrical connections use a cable with an external diameter of 6÷12mm and fully tighten the M20 cable gland.
- Close the lid tightly.
- Position the cable in such a way as to form a downward curve in the output of the M20 cable gland; in this way
condensation and/or rainwater will tend to drip from the bottom of the curve.
