Free Space Requirements; Cooling And Degrees Of Protection - ABB ACSM1 Hardware Manual

Free space requirements

The modules and their regen filter modules can be installed side by side. The main
dimensions of the regen supply module as well as free space requirements are
shown below. For more details, refer to the chapter

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
regen supply modules 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.
