The wiring diagrams, cable specifications and technical data are
indicated on the “Technical specifications” sheet supplied with the
appliance.
For the electrical connections to be correct, the appliance must:
- Be wired into an equipotential system in accordance with current
regulations. This connection must be performed between different
appliances with the terminal marked with the equipotential symbol
. The cable must have a maximum cross-section of 10 mm2 (in
accordance with standard CEI EN 60335-2-42:2003-09) and must be
yellow-green in colour.
- Be connected to the mains earth (green-yellow wire).
- Be connected to a thermal differential switch in compliance with the
regulations in force (0.03A, type A).
- Be connected to a main circuit-breaker that enables complete discon-
nection in category III overvoltage conditions.
Checks
- The copper jumper on the terminal board and the electrical cable
must be fastened together under the screw in its tightening direction,
and the electrical connections must be securely tightened before con-
necting the appliance to the electricity mains.
- Check for any electrical dispersion between the phases and the earth,
and for electrical continuity between the external casing and the
mains earth.
- Check that the power supply voltage does not deviate from the nom-
inal voltage specified on the appliance ratings plate when the appli-
ance is operating. If it does differ, wire the phases as specified on the
“Technical specifications” sheet enclosed.
