(8) Noise filter set
LEC-NFA
Noise filter set
Assembly procedure:
1) Mount a noise filter around the single wires of the actuator cable close to the driver connectors.
Next, fasten a cable tie to the shrink sleeve as shown (refer to A1).
2) Mount a noise filter to the motor cable, and fasten with a cable tie at both ends.

Single wires Cable tie
Driver Noise filter
Shrink sleeve
Motor cable
Caution
When installing a noise filter on the actuator cable, bundle all of the single wires together and then
house them inside the noise filter case. When locking the noise filter, make sure not to damage the
wires.
Attach the noise filter at the root of the cable immediately next to the connector.
When unplugging the actuator cable connectors CN2 and CN3 from the driver, remove the cable tie
and move the noise filter towards the shrink sleeve. After re-mounting, return the noise filter to its
original position and re-fasten the cable tie.
