You can freely configure the I/O signals with different fault names and reactions. Refer to
the PVS800-57B central inverters firmware manual (3AXD50000048332 [EN]).

Connection procedure


360-degree grounding at the cabinet lead-through for the control cables:
Make sure that a proper environmental seal remains after the installation.
1. Cut adequate holes in the rubber grommets in the lead-through plate.
2. Put the cables through the grommets into the cabinet.
3. Strip the plastic sheath of the cable above the lead-through plate just enough to
ensure proper connection of the bare shield.

Note: If the outer surface of the shield is non-conductive:
•
Cut the shield at the midpoint of the bare part. Do not cut the conductors or the
grounding wire (if present).
•
Turn the shield inside out to expose its conductive surface.
•
Cover the turned shield and the stripped cable with copper foil to make the shielding
continuous.
