4.1 Important notes
ƒ Use the controllers as built−in units only!
ƒ In case of contaminated cooling air (dust, lints, greases, aggressive gases):
– Take suitable preventive measures, e.g. separate air duct, installation of filters,
regular cleaning, etc.
(
Stop!
Do not install drives on top of each other in the control cabinet!
ƒ Observe installation clearances!
– You can install several controllers next to each other without free space in a
control cabinet.
– Ensure unimpeded ventilation of cooling air and outlet of exhaust air!
– Allow a free space of 100 mm at the top and at the bottom.
– If possible, the rear panel of the drive controller should be provided with a good
thermal connection to the control cabinet wall.
– In case of high load and a bad heat dissipation, the drive controller reduces the
drive power, or possibly switches off.
ƒ Do not exceed the range of the ambient operation temperature specified in the
Technical Data.
ƒ In case of permanent oscillation or agitation:
– Check whether shock absorbers are necessary.
Possible mounting positions:
Vertically on the control cabinet rear panel with mains terminals at the top.
