Appendix E ATEX Approved PowerFlex 700S, Phase II Drives in Group II Category (2) Applications with ATEX Approved Motors
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.
• When the motor is indicated for ATEX Group II Category 2 for use in
dust environments (Category 2D) the motor must be protected by an
enclosure (according to EN50281-1-1 or according to
IEC61241-1: Ex tD). Group II motors are marked with a temperature.
• The motor over temperature signal supplied to the drive must be a
normally clod 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
resultant of all required contacts wired in series.
• Refer to all product markings for additional cautions that may apply.
• Typical motor markings are contained on a motor certification nameplate
similar to the sample below.
Drive Wiring
The first input must energize “Digital Input6/Hardware Enable” on the drive
control board (TB2, terminal 16). The second input must energize the relay coil
on the DriveGuard
®
Safe-Off with Second Encoder option board (terminals 1
& 2 on the board). This option board must be installed in the drive for ATEX
applications. It is offered with a 24V DC coil only. Both input signals are wired
with respect to the drive's digital input common when using a control board with
24V I/O. Motor supplied contacts must have ratings compatible with the input
circuit ratings and applied voltage level of the drive.

IMPORTANT ATEX certification of this drive requires that two separate inputs be configured
to monitor a normally closed over temperature contact (or multiple contacts
wired in series) presented to the drive from the motor.
