Step 1: Remove Power
from the Drive
1. Turn off and lock out input power. Wait five minutes.
2. Verify that there is no voltage at the drive’s input power terminals.
3. Measure the DC bus voltage at the DC+ & DC- terminals on the Power
Terminal Block. The voltage must be zero.
!
ATTENTION: To avoid an electric shock hazard, verify that
the voltage on the bus capacitors has discharged before
performing any work on the drive. Measure the DC bus voltage
at the +DC & –DC terminals of the Power Terminal Block (DC+
& DC- in high power drives). The voltage must be zero.
