PDCOM – INSTALLATION MANUAL
• Step 3: install the VIS interface:
- Connect the 3 phases (see connector J11 in
Figure 18). The VPIS/VDS should be
connected in series, between the capacitor
divider (4.1a) and the VPIS/VDS (4.1b).
What is key with the grounding in general is to
avoid ground loops. For this reason, the shield of
the cable connecting the capacitive coupler to the
installation kit should be grounded on one side
only. We strongly advise to connect the shield to
the installation kit.
Option 1: connect wires shields and VIS interface
ground to the same hearth
