Preface
About the PowerFlex
750-Series ATEX Option
Module
The ATEX option module with the 11-Series I/O option module enables a
PowerFlex 750-Series drive and PowerFlex 755T drive products to be used in
ATEX installations. The ATEX option module helps to reduce the risk of
explosion due to an over-temperature condition in an ATEX approved motor.
In an ATEX installation, the motor is installed in a potentially explosive
atmosphere, while the drive is installed outside of the potentially explosive
atmosphere. See Figure 1 on page 11.
Catalog Numbers for ATEX
and 11-Series I/O Option
Modules
This table lists the catalog numbers for the ATEX option module and the
compatible 11-Series I/O option modules.
Catalog Numbers for Spare
Terminal Plugs
This table contains the catalog numbers for the 11-Series I/O option module
spare terminal plug kits.
WARNING: Risk of Explosion.
Do not install the PowerFlex 750-Series drive or PowerFlex 755T drive products
in a potentially explosive atmosphere.
A drive that is installed in a potentially explosive atmosphere can cause an
explosion.

Safety Concepts
The PowerFlex® ATEX option module that is installed in a PowerFlex
750-Series drive or PowerFlex 755T drive products and equipped with an
11-Series I/O option module provides an ATEX-compliant safety function.
This ATEX-compliant function provides a safe turn-off for equipment that is
installed in a potentially explosive atmosphere according to 2014/34/EU.
ATEX Directive 2014/34/EU The PowerFlex 750-Series drives and PowerFlex 755T drive products, together
with the ATEX and 11-Series I/O option modules, are compliant safety
devices under the ATEX directive 2014/34/EU, and satisfy requirements for
use in Group II, Category 2, (GD) applications with ATEX approved motors
as described here:
• Group II – The motor is installed in a potentially explosive atmosphere
that is not in a mine.
• Category 2 – The motor is likely to be exposed to an explosive
atmosphere. A high level of protection is required.
• GD – The explosive atmosphere consists of a mixture of (G) gas vapors
and (D) dust that can cause an explosion.
Certification of the drive for the ATEX group and category on its nameplate is
based on installation, operation, and maintenance according to these items:
•This user manual
• The requirements in the drive user manual and installation instructions
• The instruction manual for the motor

Chapter 1 Safety Concepts
Motor Requirements • The motor must be manufactured under the guidelines of the ATEX
directive 2014/34/EU. The motor must be installed, operated, and
maintained according to the instructions of the motor manufacturer.
• Only motors with nameplates that are marked for use on an inverter
power source, and labeled for specific hazardous areas, can be used in
hazardous areas on inverter (variable frequency) power.
• When the motor is rated ATEX Group II, Category 2 for use in gas
environments (category 2G), the motor must be of flameproof
construction, EEx d (according to EN 50018) or Ex d (according to
EN 60079-1 or IEC 60079-1). Group II motors are marked with a
temperature or a temperature code.
• When the motor is rated ATEX Group II, Category 2 for use in dust
environments (category 2D), the motor must be protected by an
enclosure (according to EN 50281-1-1, or according to
IEC 61241-1: Ex tD). Group II motors are marked with a temperature.
• The motor over-temperature signal is supplied to the drive by one of two
methods:
– A normally closed contact (open during over temperature condition)
compatible with the digital (logic) input circuitry of the drive. If
multiple sensors are required in the motor, the connection at the
drive must be the result of all required contacts that are wired in
series.
– A positive temperature coefficient (PTC) type of thermal sensor. See
Appendix A for specifications.
•See all product markings for additional cautions.
• Typical motor markings are contained on a motor certification
nameplate similar to the sample here.
ATTENTION: Follow all procedures in the standard installation and user
manuals for the ATEX-certified drive with an ATEX-certified motor. You must
also follow all additional instructions in this PowerFlex 750-Series ATEX
Option Module User Manual. Equipment damage and/or personal injury can
result if all additional instructions in this user manual are not followed.
