F-2 Instructions for ATEX Approved PowerFlex 700H Drives in Group II Category (2) Applications with ATEX Approved Motors
• 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 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
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
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.
The first input must energize the SD1 input (terminals X5-1 & X5-2) on the
drive option board (20C-DG1). The second input must energize the SD2
input (terminals X5-3 & X5-4) on the option board. This option board must
be installed in the drive for ATEX applications. It is offered with 24V DC
input only. Both input signals are wired with respect to the drive's digital
input common when using a control board with 24V I/O. Refer to Figure
2.2 on page 2-3 for wiring examples. Motor supplied contacts must have
ratings compatible with the input circuit ratings and applied voltage level of
the drive.
