Arranging the heat exchanger on the front of the control cabinet
CAUTION
When using heat exchangers the drive
controller might be damaged by moisture
condensate!
⇒
Set heat exchangers with a "permanent" temperature
setting to at least 40° C.
⇒
Set heat exchangers with integrated temperature
control in such a way that the inside temperature of
the control cabinet is not lower than the outside
temperature. Set the temperature limit to 40 °C!
⇒
Use only sealed cabinets. If the cabinet is poorly
sealed, then moisture condensate can form at the
leaky points.
⇒
If cabinets are operated over an extended period
with the door open, e.g., during commissioning or
servicing, then the drives may, at no point in time
after the doors are closed, be permitted to be cooler
than the air inside the cabinet. This means that heat
exchangers must always be operated, even after the
machine is shutdown, until the temperature of the air
inside the cabinet and all installed equipment are the
same.
