MANDATORY. As for possible high leak currents, use a protection ground wire
with a cross section of at least 10 mm² (Cu) or 16mm² (Al) or two protection
ground wires with the same cross section as that of the wires connected to
the power supply terminals. Comply with local regulations on grounding.
MANDATORY. The equipment must be protected with fuses on the three-
