MANDATORY. As for possible high leak currents, use a protection ground
wire with a cross section of at least 10 mm² (Cu) or 16 mm² (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-
phase supply lines L1, L2 and L3. Follow the instructions given in chapter 6.
