5.6 - Field control wiring
IMPORTANT: Field connection of interface circuits may
lead to safety risks: Any control box modification must
maintain equipment conformity with local regulations.
Precautions must be taken to prevent accidental electrical
contact between circuits supplied by different sources:
• The routing selection and/or conductor insulation
characteristics must ensure dual electric insulation.
• In case of accidental disconnection, conductor fixing
between different conductors and/or in the control
box prevents any contact between the conductor ends
and an active energised part.

* Connection capacities actually available for each machine, defined according to the connection terminal size, the control box access opening size and the available
space inside the control box.
** Selection simultation result considering the hypothesis indicated.
*** If the maximum calculated section is for an XLPE cable type or specified “not compatible”, this means that it exists a risk to exceed the real connection capacity
available. Special attention must be given to the selection.
Note: The currents considered are given for a machine equipped with a hydronic kit operating at maximum current.
