Chapter 15 Maintenance and TroubleshootingVFD-ED
15-6 Installation and Wiring Problems
When wiring the drive, the most common problem is incorrect wire installation or poor wiring. Please
be aware of the possible damages that poor wiring may cause to your drives.
1. If screws are not fully tightened, then sparking may occur as impedance increases.
2. If you have opened the drive and modified the internal circuit board, the internal components may
have been damaged.
Solution:
Ensure that all screws are tightened when installing the AC motor drive. If the AC motor drive functions
abnormally, send it back to Delta for repair. DO NOT try to modify or repair the internal components or
wiring.
