(1) Connection capacities actually available for each machine. These are defined according to the connection terminal size, the electrical box access opening dimensions,
and the available space inside the electrical box.
(2) Selection simulation result considering the hypotheses indicated.
(3) If the maximum calculated selection is for a 90 °C cable type, this means that a selection based on a 70 °C cable type can exceed the connection capacity actually
available. Special attention must be given to selection.
The protection against direct contact at the electrical connection point is compatible with the addition of fanout cables. The installer must determine whether these are
necessary based on the cable sizing calculation.
Note:
The currents considered are given for a machine fitted with a hydraulic module operating at the maximum current.
