When the “push-through heat sink” cooling method is used, the heat sink
of the inverter module can be mounted outside the switch cabinet, or
mounting space, in order to reduce the heat generated. The power loss
split is dependent on size, and is shown in the following table.
Size of inverter modules dependent on
cooling method
Size Power output To the outside To the inside
BG 3 3 to 4 kW 70% 30%
BG 4 5.5 to 7.5 kW 75% 25%
BG 5 11 to 15 kW 80% 20%
BG 6 22 to 37 kW 85% 15%

1) Max. outer dimensions to be maintained
2) The bending radii of the cables must be taken into account for the mounting clearance below
Note: The modules can be mounted side-by-side. As from size 6 an additional side clearance of 50 mm is required.
