To optimize the thermal efficiency, it is recommended to adhere to the following installation
guidelines:
• Guarantee the maximum possible distance between the input and output busbars. See the example
Figure 114.
• Guarantee the maximum use of the surface of the terminal. See the example Figure 115.
• Make sure that the distance between the holes and the end of the terminal and between the holes
and extremity of the busbar is the same. See the example Figure 116.
• Make sure that, accordingly to the number of busbars and terminal tangs, the busbars of the lateral
phases are as distant as possible from the busbars of the central phase. See the example Figure 117.
