ATEX Approved PowerFlex 700S, Phase II Drives
in Group II Category (2) Applications with ATEX
Approved Motors
General Information
This document provides information on operation of an ATEX 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 700S Phase II drive must have the
DriveGuard® Safe-Off with Second Encoder option board installed for ATEX
applications. Consult the option board User Manual for installation instructions
if necessary.
The drive is manufactured under the guidelines of the ATEX directive 94/9/EC.
The 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 this
document and to the requirements found in the User Manual and appropriate
Motor Instruction Manual(s).
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.
