Cubicle with forced cooling
Cubicles with forced cooling (Fig. 4/2) serve for the assem-
bly of functional units with a very high power loss, for
example, for withdrawable units with a frequency con-
verter up to 45 kW.
On the left, the cubicles are equipped with a 100 mm wide
ventilation duct. The width of the cable connection com-
partment is reduced by 100 mm so that the cubicle width
does not change as compared to a cubicle without forced
cooling.
The withdrawable units with forced cooling are equipped
with fans. The fan control comes completely configured.
No further settings are required upon start-up of the
switchboard. The fans are dimensioned such that the
second fan can ensure the required cooling of the with-
drawable unit if a fan fails. A failure message will be issued.
The cubicles with forced cooling comply with degree of
protection IP31. Connection is effected at the front of the
cubicle.
The other cubicle characteristics are identical to the cubicle
without forced cooling. All mounting designs and func-
tional units without forced cooling can be applied.
