K Handling
Observe the following precautions when wiring or performing maintenance for an Inverter.
nWiring 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 sequences carefully.
nMagnetic Contactor Installation
Do not start and stop operation frequently with a magnetic contactor installed on the power supply line. Doing
so can cause the Inverter to malfunction. Do not turn the Inverter ON and OFF with a magnetic contactor more
than one time every 30 minutes.
nMaintenance and Inspections
After turning OFF the main circuit power supply, always confirm that the CHARGE indicator is not lit before
performing maintenance or inspections. The voltage remaining in the capacitor may cause electric shock.
