Installation and Wiring
You must follow the installation steps described in this installation and wiring
section. The installation and wiring steps must be performed by qualified drive
installation personnel. The PowerFlex 750-Series ATEX option module with an
11-Series I/O module are part of an ATEX safety control system.
Perform a Risk Assessment of
the Operational Environment Before you begin the installation, perform a risk assessment to compare the
ATEX option specifications with the potentially explosive atmosphere where you
want to install the system. See
Safety Concepts on page 9 .
Perform a Safety Analysis of
the Motor The ATEX safety system includes the thermal sensor in the motor and the wiring
to the ATEX daughter card.
Verify Operation on page 29 gives methods to
functionally test the system from the input to the ATEX daughter card, but these
tests do not verify the thermal sensor response or the wiring from the motor.
Follow the motor manufacturer's recommendations for safe use of the motor in
ATEX installations and possible functional test procedures.
