Installation and Connection
In order to prevent a malfunction caused by interference voltages on the
control inputs, the following steps should be observed:
• Establish a true earth ground for all ground connections!
• Do not connect drive signal commons to earth ground!
• Use shielded cable with twisted pair wires!
• Terminate shield wires to earth ground, only at inverter!
• Separate control and power wires by 8" or more!
• Control and power wires should cross at a right angle!
