BEFORE YOU BEGIN Read this document carefully and store it with the Installation Manual for

future reference.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Read and understand this document and bulletin atv71e_installation_manual_en_v3 before installing or operating the Altivar 71 drive controller. 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 controller, 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 controller:

— 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 “Bus Voltage Measurement Procedure” on page 3 of this bulletin 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 controller.

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

DANGER

UNINTENDED EQUIPMENT OPERATION

With regard to the connection diagrams for safety applications described in the Altivar

• Refer to IEC 61508, Functional Safety of

Electrical/Electronic/Programmable Electronic Safety Related System, Parts 1–7, 2000.

• Completely understand the applications and environment defined by Safety Integrity Level 2 (SIL2) within IEC 61508.

• Do not exceed SIL2 ratings in the application of the product.

• The following terms are used in this document are used in the context of Safety Integrity Level 2 of IEC 61508: power removal safety function, safety-type signals, safely, and safe conditions.

Failure to follow these instructions can result in death, serious injury, and equipment damage.

PRELIMINARY RECOMMENDATIONS

Installing the AC choke on ATV71H•••Y

Insert the following safety message to this section.

drives

CAUTION

CONTROLLER DAMAGE

A 3–5% impedance input line reactor is required on all ATV71HC••Y drive controller installations.

Failure to follow these instructions can result in equipment damage.

POSITION OF THE CHARGING LED Replace the Bus Voltage Measurement Procedure section with the

following:

Bus Voltage Measurement Procedure Before working on the drive controller, remove all power and wait 15

minutes to allow the DC bus to discharge. Then measure the DC bus voltage between the PA/+ and PC/– terminals.

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 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.

4. If the DC bus capacitors do not discharge completely, contact your local

Schneider Electric representative. Do not repair or operate the drive controller.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Read and understand the precautions in “Before you begin” on page 2 of this Errata sheet before performing this procedure.

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