4.2 Electric system
All the electrical components must be grounded. This applies both to the electrical components themselves and the
control devices. To this end, ensure that the grounding wire is correctly connected. For safety reasons, the grounding
conductor must be approx. 100 mm longer than the phase conductors. In the event of an accidental disconnection of
the cable, the grounding terminal must be the last to detach itself.
In order to avoid the danger of fulguration due to direct or indirect contacts with the live parts, it is necessary that the
electric power supply line be adequately protected by a special magnetothermal differential switch with a cut-off
threshold of 0.03 Ampere and a maximum cut-off time of 1 second.
The cut-off power of the switch must be 10 kA and the rated current In = 4 A.
NOTE: At the end of all connecting operations, make sure that pipes and wires are safe from
impacts and carefully fixed.
