Connecting a Surge Suppressor
A surge suppressor suppresses transient voltages generated from switching an inductive load near the drive. Inductive loads
include magnetic contactors, relays, valves, solenoids and brakes. Always use a surge suppressor or diode when operating
with an inductive load.
Note: Never connect a surge suppressor to the drive output.

Connecting a Noise Filter
n
Input-Side Noise Filter
Drive
outputs generate noise as a result of high-speed switching. This noise flows from inside the drive back toward the power
supply, possibly affecting other equipment. Installing a noise filter to the input side of the drive can reduce the amount of noise
flowing back into the power supply. This also prevents noise from entering the drive from the power supply.
• Use a noise filter specifically designed for AC drives.
• Install the noise filter as close as possible to the drive.

Refer to EMC Filter Installation on page 236 for details about EMC filter selection and installation in order to make the
drive compliant with European standards EN61800-3 and the EMC guidelines.

Output-Side Noise Filter
A noise filter on the output side of the drive reduces inductive noise and radiated noise. Figure 8.7 illustrates an example of
output-side noise filter wiring.
NOTICE: Do
not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improper application of noise filters could
result in damage to the drive.
