Safety Information

Important Information

NOTICE

Read these instructions carefully, and look at the equipment to become familiar with the device before trying to install, operate, or maintain it. The following special messages may appear throughout this documentation or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure.

The addition of this symbol to a Danger or Warning safety label indicates that an electrical hazard exists, which will result in personal injury if the instructions are not followed.

This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.

DANGER

DANGER indicates an imminently hazardous situation, which, if not avoided, will result in death or serious

injury.

WARNING

WARNING indicates a potentially hazardous situation, which, if not avoided, can result in death, serious

injury or equipment damage.

CAUTION

CAUTION indicates a potentially hazardous situation, which, if not avoided, can result in injury or

equipment damage.

NOTICE

NOTICE, used without the safety alert symbol, indicates a potentially hazardous situation which, if not

avoided, can result in equipment damage.

PLEASE NOTE

The word "drive" as used in this manual refers to the controller portion of the adjustable speed drive as defined by NEC.

Electrical equipment should be installed, operated, serviced, and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this product.

Safety instructions

The information provided in this manual supplements the product manuals.

Carefully read the product manuals before using the product.

Read and understand these instructions before performing any procedure with this drive.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

z Read and understand this manual before installing or operating the drive. Installation, adjustment, repair,

z The user is responsible for compliance with all international and national electrical code requirements with

z Many parts of this drive, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH.

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

z DO NOT short across terminals PA and PB or across the DC bus capacitors.

z Before servicing the drive:

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

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

DANGER

and maintenance must be performed by qualified personnel.

respect to grounding of all equipment.

Use only electrically insulated tools.

- 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.

- Measure the voltage of the DC bus between the PA and PB terminals to ensure that the voltage is less than 42 Vdc.

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

DANGER

UNINTENDED EQUIPMENT OPERATION

z Read and understand this manual before installing or operating the drive.

z Any changes made to the parameter settings must be performed by qualified personnel.

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

WARNING

DAMAGED DRIVE EQUIPMENT

Do not operate or install any drive or drive accessory that appears damaged.

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

Before you begin

WARNING

LOSS OF CONTROL

z The designer of any wiring scheme must consider the potential failure modes of control channels and, for

certain critical control functions, provide a means to achieve a safe state during and after a channel failure. Examples of critical control functions are emergency stop and overtravel stop.

z Separate or redundant control channels must be provided for critical control functions.

z Each implementation of a control system must be individually and thoroughly tested for proper operation

before being placed into service.

z System control channels may include links carried out by the communication. Consideration must be

given to the implications of unanticipated transmission delays or failures of the link

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

1. For additional information, refer to NEMA ICS 1.1 (latest edition), “Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control” and to NEMA ICS 7.1 (latest edition), “Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems.”

CAUTION

INCOMPATIBLE LINE VOLTAGE

Before turning on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range shown on the drive nameplate. The drive may be damaged if the line voltage is not compatible.

Failure to follow these instructions can result in injury or equipment damage.

NOTICE

RISK OF DERATED PERFORMANCE DUE TO CAPACITOR AGING

The product capacitor performances after a long time storage above 2 years can be degraded. In that case, before using the product , apply the following procedure:

z Use a variable AC supply connected between L1 and L2 (even for ATV61/71pppN4 references). z Increase AC supply voltage to have:

- 25% of rated voltage during 30 min

- 50% of rated voltage during 30 min

- 75% of rated voltage during 30 min

- 100% of rated voltage during 30 min

Failure to follow these instructions can result in equipment damage.
