ELECTRICAL INSTALLATION
It is recommended that the distance between the SATEC VRM and SATEC meter should not exceed 2 meters, using cabling featuring minimum 600V insulation.
When using SATEC VRM, the correct ratio coefficient must be set with PAS software software (“Basic Setup” tab):
- Using the PRO Series meters, enter “ratio” = 3.5
- Using the PM130 PLUS, enter “ratio” = 11 Ratio coefficient = 11
