Using Cooling Units in the Control Cabinet
Unless the rated data are reduced the drive controller may only be
operated up to a specified maximum ambient temperature (see
chapter 4.3). It is therefore possible that a cooling unit will be required.
CAUTION
Possible damage to the controller
Operational safety of the machine endangered
⇒
Note the following instructions
Due to their operating principle condensation water is formed when
cooling units are used. For this reason, please observe the following
information:
•
Always position cooling units in such a way that condensation water
cannot drip onto electronic equipment in the control cabinet.
•
Position the cooling unit in such a way that the blower of the cooling
unit does not spray accumulated condensation water onto electronic
equipment.
