TOMPYEUOQ2A03C AC Drive Q2A Installation and Operation Instructions
4.
Ground the wire shielding on the drive side and motor side.
A - Drive
B - 10 m (32.8 ft.) maximum
C - Motor
D - Metal conduit
E - Grounding wire
Figure 1.5 Wiring the Drive and 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.
NOTICE
Move the EMC switch screw or screws to the OFF position for networks that are not symmetrically grounded.
Failure to obey can cause damage to the drive.
Make sure that the symmetric grounding network is applied, and install the screw or screws in the ON position to
enable the built-in EMC filter in compliance with the EMC Directive.
Figure 1.6 Symmetric Grounding
NOTICE
When operating the drive with a non-grounding network, high resistance grounding, asymmetric grounding
network, install the screw or screws in the OFF position to disable the built-in EMC filter. Failure to obey the instructions can
damage the drive.
If you lose an EMC filter switch screw, install the correct size screw with the correct tightening torque.
NOTICE
Only use the screws specified in this manual. Failure to obey could damage the drive.
