that a component fails in the drive’s power circuitry. The drive’s electronic pro-
tection circuitry is designed to clear drive output short circuits and ground
faults without blowing the drive input fuses. The table below shows the VSC
input fuse ratings.
To protect the VSD most effectively, use fuses with current-limiting function.
