îš‹ Handling
Observe the following precautions when wiring or performing maintenance for an Inverter.
îš„Wiring Check
The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.
Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully.
îš„Magnetic Contactor Installation
If a magnetic contactor is installed in the power supply line do not exceed one start per hour. Switching more
often can damage the inrush current prevention circuit.
îš„Maintenance and Inspections
After turning OFF the main circuit power supply it can take several minutes before the DC bus is discharged
completely. The CHARGE LED, indicating if the DC bus is charged, glows above a voltage of 10VD.
