Connect the noise filter ground wire directly to the ground plate.
Do not connect the noise filter ground wire to other ground wires.
If a noise filter is located inside a control panel, first connect the noise filter ground wire and the
ground wires from other devices inside the control panel to the ground plate for the control panel,
then ground the plates.
3.7.3 Connecting a Reactor for Harmonic Suppression
The SERVOPACK has reactor connection terminals for power supply harmonic suppression that can be used
as required. Refer to Σ -V Series Product Catalog (No.: KAEP S800000 42) for precautions on selecting an AC
or DC reactor and its specifications.
Connect a reactor as shown in the following diagram.
Note 1. Connection terminals for DC reactor 1 and 2 are short-circuited at shipment. Remove the lead wire for
short-circuit, and connect a DC reactor.
2. Reactors are not included. (Sold separately.)
3. DC reactors cannot be connected to SERVOPACKs with a single-phase 100-V power input.
