Use a properly ratedvoltage-sensing device when performing this procedure. To measure theDC bus voltage:1. Disconnect all power.2. Wait 15 minutes to allow the DC bus to discharge.3. Measure the voltage of the DC bus between the PA/+ and PC/–terminals to ensure that the voltage is less than 42 Vdc. These terminalsare clearly labeled on each drive.4. If the DC bus capacitors do not discharge completely, contact your localSchneider Electric representative. Do not repair or operate the drive.
