30 Planning the cabinet assembly
Note: EMC filters of type JFI-x1 mounted directly above the drive module do not
increase the free space requirements. (For EMC filters of type JFI-0x, see the
dimension drawing of the filters on page 119.)
The temperature of the cooling air entering the unit must not exceed the maximum
allowed ambient temperature (see
Consider this when installing heat-generating components (such as other drives and
mains chokes) nearby.
Cooling and degrees of protection
The cabinet must have enough free space for the components to ensure sufficient
cooling. Observe the minimum clearances given for each component.
The air inlets and outlets must be equipped with gratings that
• guide the air flow
• protect against contact
• prevent water splashes from entering the cabinet.
The drawing below shows two typical cabinet cooling solutions. The air inlet is at the
bottom of the cabinet, while the outlet is at the top, either on the upper part of the door
or on the roof.
