Damage to the CU240E-2 PN and CU240E-2 PN-F Control Units in the event of a short-
circuit of the 24 V output
It is possible that the Control Units are defective if the following conditions occur
simultaneously:
1. A short-circuit to the 24 V output occurs at terminal 9 when the converter is operating.
2. The ambient temperature is at the upper permitted limit.
3. You have connected an external 24 V supply to terminals 31 and 32 and the voltage at
terminal 31 is at the upper permitted limit.
In order to rule out damage to the Control Units, you have to prevent all three conditions
occurring simultaneously.
Selecting the pre-assignment for the terminal strip
The inputs and outputs of the frequency inverter and the fieldbus interface have specific
functions when set to the factory settings.
When you put the frequency inverter into operation, you can change the function of each of
its inputs and outputs and the setting of the fieldbus interface.
To make the setting process easier, the inverter has various predefined assignments
(macros).
Only the inputs and outputs whose functions change by selecting a specific assignment, are
shown on the following pages.
To select one of the inverter's pre-assigned settings, proceed as follows:
1. Think about which of the input and output functions you are using in the application.
2. Find the I/O configuration (macro) that best suits your application.
3. Note the macro number of the corresponding default setting.
You must set this macro number when putting the frequency inverter into operation.
You have found the appropriate inverter pre-assignment.
