Electrical Installation - YASKAWA GA500 Maintenance & Troubleshooting

Do not examine, connect, or disconnect wiring on an energized drive. Before servicing,
disconnect all power to the equipment and wait for the time specified on the warning label at a
minimum. The internal capacitor stays charged after the drive is de-energized. The charge
indicator LED extinguishes when the DC bus voltage decreases below 50 Vdc. When all
indicators are OFF, measure for dangerous voltages to make sure that the drive is safe.
If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
De-energize the drive and wait 5 minutes minimum until the Charge LED turns off. Remove the
front cover and terminal cover to do work on wiring, circuit boards, and other parts. Use
terminals for their correct function only.
Incorrect wiring, incorrect ground connections, and incorrect repair of protective covers can cause death or
serious injury.
Correctly ground the drive before you turn on the EMC filter switch.
If you touch electrical equipment that is not grounded, it can cause serious injury or death.
Use the terminals for the drive only for their intended purpose. Refer to the technical manual
for more information about the I/O terminals.
Wiring and grounding incorrectly or modifying the cover may damage the equipment or cause injury.
