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
.

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.
