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
EMC
apart)
• Lay crossings in a right angle (in case it cannot be prevented)
