any work on the drive. Wait five minutes for the capacitors to
discharge. Then, measure the DC bus voltage at the DC- and
DC+ terminals or at the DC- and P2 terminals on the power
terminal block. The voltage must be zero.
A darkened LCD display and LEDs are not an indication that
capacitors have discharged to safe voltage levels.
