Control Cabinet Ventilation (Schematic Diagram)
Only clean air gets into the control cabinet through the filter at the air intake
opening. The control cabinet fan behind the air intake opening delivers the air
into the control cabinet and generates overpressure in the control cabinet.
This overpressure prevents unclean air from entering into the control cabinet
through potentially leaky points (leaky cable passages, damaged seals, etc.).
12.1.2
Arranging the Cooling Units
Unless the nominal data are reduced, the drive controller may only be operat‐
ed up to a specified maximum ambient temperature. A cooling unit might
therefore be required.
Possible damage to the drive controller! Op‐
erational safety of the machine endangered!
NOTICE
Observe the instructions below.
Avoiding Dripping or Spraying Wa‐
ter
Due to their operating principle, condensation water is formed when cooling
units are used.
For this reason, observe the following aspects:
●
Always position cooling units in such a way that condensation water
cannot drip onto the devices in the control cabinet.
●
Position the cooling unit in such a way that the fan of the cooling unit
does not spray accumulated condensation water onto the devices in the
control cabinet. Mount the air duct in the control cabinet accordingly.
