Install A Drive To Conform To The Emc Directive; Enable The Internal Emc Filter - Omron Q2A-A Series Installation & Operation Instructions

1 English
WARNING Electrical Shock Hazard. Do not immediately energize the drive or operate peripheral devices after the drive
blows a fuse or trips an RCM/RCD. Wait for the time specified on the warning label at a minimum and make sure that all
indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of the problem. Contact the
manufacturer before energizing the drive or peripheral devices if the cause is not known. Failure to obey can cause death or
serious injury and damage to the drive.

EMC Directive
All drives were tested in accordance with European standard IEC/EN 61800-3:2004/A1:2012, and comply with
the EMC Directive.
Use drives with built-in EMC filters or install external EMC filters to the drive input side to comply with the
EMC Directive.

Install a Drive to Conform to the EMC Directive

Install drives with this procedure to comply with the EMC Directive when the drive is a single unit or installed in
a larger device.
1.
Install the drive on a grounded metal plate.
2.
Wire the drive and motor.
3.

Enable the internal EMC filter.

4.
Ground the wire shielding on the drive side and motor side.
A - Drive
B - 10 m (32.8 ft.) maximum
C - Motor
5.
Use a cable clamp to ground the motor cable to the metal plate.
Note:
Make sure that the protective ground wire complies with technical specifications and local safety standards.
6.
Connect an AC or DC reactor to decrease harmonic distortion.
Note:
• To maintain compliance with IEC/EN 61000-3-2 on drive models 2004, 2006, 4002, and 4004, install a DC reactor.
• The main circuit terminal block for the drive and the terminal blocks for the DC reactor come in different shapes. Correctly
prepare the ends of the wiring.
■
Enable the Internal EMC Filter
Move the screw or screws to turn ON and OFF (enable and disable) the EMC filter. The EMC filter switch screw
or screws are installed in the OFF position by default.
WARNING
Electrical Shock Hazard. Make sure that the power to the drive is OFF and the CHARGE LED light is OFF
before you move the EMC filter screw or screws. Failure to obey could cause death or serious injury.
WARNING Electrical Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. Failure to
obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. Ground the neutral point on the power supply to comply with the EMC Directive
before turning on the EMC filter or if there is high resistance grounding. If the EMC filter is switched ON without the neutral point
being grounded or if there is high resistance grounding, it can cause death or serious injury.
WARNING Electrical Shock Hazard. Connect the ground cable correctly. Failure to obey can cause death or serious
injury.
NOTICE
When disabling the internal EMC filter, move the screws from ON to OFF and then tighten to the specified
torque. Completely removing the screws or tightening the screws to an incorrect torque may cause drive failure.
