5.1 CONNECTIONS
1) Separate the engine control cables or power cables from the VLW602 connection cables.
2) Remove the caps from the cable glands and open the cover by unscrewing the screws.
3) Lead the cables into the transmitter through the cable glands.
4) Close the cap and tighten the cable glands
5.2 RECOMMENDATIONS FOR EXTERNAL MOUNTING
To avoid the humidity infiltration inside the housing is recommended:
- For electrical connections, tighten the PG9 cable gland..
- fully tighten the cap.
- position the cable so that it forms a downward curve at the PG9 output; in this way the condensation and/or
rain water will tend to drop from the curve bottom.
- The two central cable glands are arranged for the PTU sensor connection cables.
