Before you Begin Read and follow these precautions before performing any procedure with

this drive.

The word “drive” as used in this bulletin refers to the controller portion of the adjustable speed drive as defined in the National Electrical Code

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Read and understand this manual before installing or operating the Altivar 61 or 71 drive. Installation, adjustment, repair, and maintenance must be performed by qualified personnel.

• The user is responsible for compliance with all international and national electrical code requirements with respect to grounding of all equipment.

• Many parts of this drive, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH. Use only electrically insulated tools.

• DO NOT touch unshielded components or terminal strip screw connections with voltage present.

• DO NOT short across terminals PA/+ and PC/– or across the DC bus capacitors.

• Before servicing the drive:

— Disconnect all power, including external control power that may be

present.

— Place a “DO NOT TURN ON” label on all power disconnects.

— Lock all power disconnects in the open position.

— WAIT 15 MINUTES to allow the DC bus capacitors to discharge.

Then follow the “DC Bus Voltage Measurement Procedure” on page 2 to verify that the DC voltage is less than 42 V. The drive LED is not an indicator of the absence of DC bus voltage.

• Install and close all covers before applying power or starting and stopping the drive.

Introduction 09/2009

Introduction This document provides:

• Information regarding short circuit current rating (SCCR) and

overcurrent protection device (OCPD) for the 200–240 Vac, 380–480 Vac, and 500–600 Vac three-phase Altivar and Altivar 71 (ATV71) drives.

• Information on drives in single-phase installations with and without

line reactors.

Use this information in addition to the ATV61 and ATV71 Simplified Manuals and as a supplement to the recommendations listed on the drive nameplate. Only the ATV61 and ATV71 drive part numbers available for each supplementary rating type are listed in this document.

DC Bus Voltage Measurement Procedure

Measuring the DC bus voltage

Before working on the drive, turn it off and wait 15 minutes to allow the DC bus to discharge. Then measure the DC bus voltage.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Read and understand the instructions on page 1 before performing this procedure.

Failure to follow these instructions will result in death or serious injury.

The DC bus voltage can exceed 1,000 Vdc. Use a properly rated voltagesensing device when performing this procedure. To measure the DC bus voltage:

1. Disconnect the drive power supply.

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.

4. If the DC bus capacitors do not discharge completely, contact your local Schneider Electric representative. Do not repair or operate the drive.

Minimum enclosure volume allows the specified SCCR. Application specific thermal requirements may require a larger enclosure.

There is no supplementary rating for an ATV61HD11N4 or ATV71HD11N4 drive installed with a Type 1 conduit box or in a Type 1 enclosure. For the ATV61HD11N4 or ATV71HD11N4 drive installed in a metallic enclosure, a 100 kA short circuit current rating is possible only in a Type 12 enclosure.
