ike all electrical equip ment, drives create heat and they therefore have a major influence on the temperatures inside enclosures. Drives are often quoted as having efficiency of 97 percent, so one with a rated output of 150kW can produce as much as 4.5kW of heat.
AMB E AMBIENI NT TEMPERA EMPERATURE ATURE
As well as the heat loss inside the enclosure, ambient temperatures within a production facility will also have an i mpact on the temperatures that a drive is operating within. A typical enclosure climate control systemis designed for an internal enclosure temperature of 35°C. Thismeans that the performance of a cooling unit should be specified so that the avera ge internal
