Analog inputs
Connect unused analog inputs to common, to prevent set value fluctuations!
*) Connect potential equalizing line only
if a potential difference of > 30 V exists
between the controls. The internal
resistance is reduced to 30 k

Digital inputs
In order to prevent a malfunction caused by interference voltage supply on the control
inputs, the following directions should be observed:
Å Use shielded/drilled cables
Å Lay shield on one side of the inverter onto earth potential
Å Lay control and power cable separately (about 10...20 cm apart)
Å Lay crossings in a right angle (in case it cannot be prevented)
EMC
Use of external voltage supply
Use of internal voltage supply
