It is forbidden to lay the power supply and room thermostat cables in the vicinity of any hot surfaces (delivery pipes). If there
is a risk of contact with hot parts, with temperatures exceeding 50°C, a suitable type of cable must be utilized.
2.11.1 Cable sizing
The installer is responsible for cable sizing, which depends on the characteristics and regulations that will apply. The tables below
may help sizing cables correctly.

(1) Connection capacity really available for each machine. They are defined according to the size of the connection terminals, the size
of the access opening of the electric box and the space available inside the electric box.
(2) Result of selected simulation considering the hypothesis indicated.
(3) If the maximum section is calculated for an XLPE cable, it means that a selection based on the PVC cable can exceed the connection
capacity really available. You need to pay attention to the selection. The direct contact protection at the electric connection point
is compatible with an additional terminal extension. The installer must determine whether this is required according to the cable
sizing calculation.
