Instructions for ATEX Approved PowerFlex
700H Drives in Group II Category (2)
Applications with ATEX Approved Motors
General Information
This document provides information on operation of an ATEX
(1)
Approved
drive and ATEX approved motor. The motor is located in a defined
hazardous environment, while the drive is not. A protective system is
required to stop current flow to the motor when an over temperature
condition has been sensed in the motor. When sensed, the drive will go into
a stop condition. To restart the drive, the over temperature condition must be
resolved, followed by a valid start command to the drive. The PowerFlex
700H drive must have the 20C-DG1 option board installed in slot B of the
control assembly for ATEX applications. Refer to 700H Control Circuit
Board Designations on page 2-2 for more information.
The drive is manufactured under the guidelines of the ATEX directive 94/9/
EC. These drives are in Group II Category (2) Applications with ATEX
Approved Motors. Certification of the drive for the ATEX group and
category on its nameplate requires installation, operation, and maintenance
according to the requirements found in this document and the appropriate
Motor Instruction Manual(s).
Motor Requirements
• The motor must be manufactured under the guidelines of the ATEX
directive 94/9/EC. It must be installed, operated, and maintained per the
motor manufacturer supplied instructions.
• Only motors with nameplates marked for use on an inverter power
source, and labeled for specific hazardous areas, may be used in
hazardous areas on inverter (variable frequency) power.
• When the motor is indicated for ATEX Group II Category 2 for use in
gas environments (Category 2G) the motor must be of flameproof
construction, EEx d (according to EN50018) or Ex d (according to
EN60079-1 or IEC60079-1). Group II motors are marked with a
temperature or a temperature code.
(1)
ATEX is the French acronym for “Atmosphères Explosibles” which translates to Explosive Atmospheres in
English.

ATTENTION: Operation of this ATEX certified drive with an
ATEX certified motor that is located in a hazardous environment
requires additional installation, operation, and maintenance
procedures beyond those stated in the standard user manual.
Equipment damage and/or personal injury may result if all
additional instructions in this document are not observed.
