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!
Observe the instructions below.
