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.
See 700H Control Circuit Board Designations on page

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.
