ATTENTION: To avoid an electric shock hazard, verify that the
voltage on the bus capacitors has discharged completely before
servicing. After removing power to the drive, wait 5 minutes for
the bus capacitors to discharge. Measure the DC bus voltage at the
DC+ and DC- TESTPOINT sockets on the front of the power
module (Figure 3.14
or Figure 3.27). The voltage must be zero.
