WARNING
In case cables with cross-sections smaller than the minimum allowable cross-section for
the cable lug are used, the special adaptors are required in order not to affect the
equipment degree of protection.
The recommended cable cross-section relates to 90°C isolated cables, 45°C ambient
temperature, installed in air.
Always check cable layout conditions.
