Grounding
Ensure equipotential bonding between the cabinets that are not screwed together (between master and
slaves). Use a single-core, yellow-green cable with a cross section of min. 16 mm ², which is connected
to the housing frame using terminals and screws. This will prevent the current from flowing in the shield of
the communication cables (due to different potentials of the inverters).
You should also carry out the equipotential bonding if all inverters are grounded via a PEN conductor.
