Planning the cabinet installation 41
Free space at the side and front of the drive module
The figure below shows the required free space in a unit with motor busbars connected to
the left-hand side of the module. The required free space when no vertical busbars are
used is also shown.
1) When cables are connected to the output busbars of the pedestal 100 mm (3.94 in.) free space around
the busbars is required for cooling.
2) When cables connected to the vertical output busbar terminals 50 mm (1.97 in.) free space around the
busbar terminals is required for cooling.
3) The required free space in front of the unit depends on the gratings in the cabinet door:
• 0 mm (0 in.) with air inlets as high as the grating in the module 1120 mm (44 in.)
• 150 mm (5.91 in.) with air inlets at the lower part of the cabinet only.
4) No extra space is needed at the back.
