Unless the nominal data are reduced, the drive controller may only be operated
up to a specified maximum ambient temperature. A cooling unit might therefore
be required.
NOTICE
Observe the instructions below.
Due to their operating principle, condensation water is formed when cooling
ter
units are used.
For this reason, observe the following aspects:
● Always position cooling units in such a way that condensation water can‐
not drip onto the devices in the control cabinet.
