Connection of the Control

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