Cooling And Degrees Of Protection - ABB ACSM1 Hardware Manual

The temperature of the cooling air entering the unit must not exceed the maximum
allowed ambient temperature (see
data). Consider this when installing heat-generating components (such as other
drives, mains chokes and braking resistors) 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.
