Free Space Around The Filter; Clearance Distances From The Input And Output Terminals And Coil Surfaces; Cooling - ABB ACS800 Hardware Manual

Free space around the filter

Free space is required around the unit for cooling as follows. The distances apply to
natural convection. With forced cooling, less free space is required.
50 mm
(1.97 in.)

Clearance distances from the input and output terminals and coil surfaces

Busbar and enclosure clearance distances from the input and output terminals and
coil sufaces must be at least 15 mm (0.59 in.). Pay attention to the local regulations.
Note: Due to high temperature of the coil surfaces during operation, route the motor
cables at least 50 mm (1.97 in.) away from the coil surfaces and secure them
appropriately.

Cooling

The filters are designed to cool by natural convection. Ensure that there is enough
fresh cooling air available and that the hot air can freely escape from the filter
enclosure or cubicle. The air space above the filter is hot [up to 70 °C (158 °F)
depending on the installation and operating conditions]. Take this into account in the
cabinet design.
