PROTECTIVE GROUND
The metallic structure is connected to the protective earth connection, as shown in Figure 13, which should be
interconnected with the low voltage switchboard earth connection.
Cable section of protective earth line, depending on the power rate of EV-HC, can be consulted in Table 3 on
page 9.
