In order to prevent a malfunction caused by interference voltage on the
control inputs, the following steps should be observed:
• Establish a common ground point for all ground connec-
tions.
• Use shielded cable with twisted pair wires.
• Terminate shield wires to earth ground, only at inverter.
• Separate control and power wires 8" or more apart.
• Control and power wires to cross at a right angle.
