2.2 Mounting
NORDAC SK 750E frequency inverters come in different frame sizes according to their power ratings. The
place where the device is mounted should be planned with care so that its performance will not be impaired.
To protect the devices from overheating, sufficient ventilation must be ensured. We recommend that a clear-
ance of 100 mm minimum be maintained between the frequency inverter and any components located above
or below it so as to encourage the air to flow freely in between.
No gaps need however to be provided between devices when they are installed side by side. The mounting
position is always vertical.
Make provisions for the hot air above the devices to be effectively removed!
If several inverters are arranged on top of one another, the temperature of the air that is drawn in should not
exceed the specified limit (see also Section 9 Technical Data). It would be a good idea for instance to provide
an "obstacle" (e.g. a cable duct) between the inverters which will divert the upward current of warm air.
