Electrical precautions
MANDATORY. For protection against high leak currents (3.5 mA AC or
10 mA DC), use a protective earth conductor with a cross-section of at
least S/2, where S (mm²) is the cross section of the conductors connected
to the power supply terminals.
For S (mm²) that are up to and including 35 mm², use a protective earth
conductor with a cross section of at least 10 mm² (Cu) or 16 mm² (Al) or
two protective earth conductors with the same cross section as that of the
wires connected to the power supply terminals.
When making protective earth connections, ensure to comply with local
standards. Note the symbol indicating this precaution indicated by an
arrow in figure
F. H8/9
.
F. H8/9
Precaution against high leakage currents. Warning symbol on the upper part of
the units.

WARNING. The system must always be installed before applying voltage
according to the EN 60204-1 standard. Ignoring it may cause serious
injuries, even death.
