18-6 Wiring and Installation Problem
When wiring the drive, the most common problem is wrong wire installation or poor wiring.
Please be aware of the possible damages that poor wiring may cause to your drives:
1. Screws are not fully fastened. Occurrence of sparks as impedance increases.
2. If a customer has opened the drive and modified the internal circuit board, the internal
components may have been damaged.
Solution:
Ensure all screws are fastened when installing the AC motor drive. If the AC motor drive functions
abnormally, send it back to the repair station. DO NOT try to reassemble the internal components or
wire.
