5. Connect an AC reactor or DC reactor to decrease harmonic distortion. Refer to DC Reactors on page 186
to select a DC reactor.
Note:
• To comply with EN 61000-3-2 on drive models 2001 to 2006, 4001 to 4004, install a DC reactor.
Ground Wiring
WARNING! Electrical Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. If you touch the
internal components of an energized drive, it can cause serious injury or death.
WARNING! Electrical Shock Hazard. Ground the neutral point on the power supply of drive models BxxxE, 2xxxE, and 4xxxE to
comply with the EMC Directive before you turn on the EMC filter or if there is high resistance grounding. If you turn ON the EMC
filter, but you do not ground the neutral point, it can cause serious injury or death.
Enable the Internal EMC Filter
On drive models BxxxE, 2xxxE, and 4xxxE, move the screw or screws to turn ON and OFF (enable and disable)
the EMC filter.
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. The EMC filter switch screw or screws are
installed in the OFF position by default.
WARNING! Electrical Shock Hazard. Disconnect all power to the drive, wait for the time specified on the warning label, and
check the drive for dangerous voltages before you remove covers or touch EMC filter screws. If you touch the screws when
there are dangerous voltages, it will cause serious injury or death.
WARNING! Electrical Shock Hazard. Do not remove covers or touch circuit boards while the drive is energized. If you touch the
internal components of an energized drive, it can cause serious injury or death.
WARNING! Electrical Shock Hazard. Ground the neutral point on the power supply of drive models BxxxE, 2xxxE, and 4xxxE to
comply with the EMC Directive before you turn on the EMC filter or if there is high resistance grounding. If you turn ON the EMC
filter, but you do not ground the neutral point, it can cause serious injury or death.
