AC Line Filters

In addition to EMI/RFI safeguards inherent in the DC3RD

design, external filtering is required. Reliance Electric

requires the Corcom® AC line filters listed in Table 3. Use

model 5VR1 with drives rated for 3 ADC or below, and

model 20VV1 with drives rated for 10 ADC or below.

Table 3. AC Line Filters

Corcom

Model Number 5VR1 20VV1

Rated Current 5 A 20 A

Inductance 1.032 mH 0.88 mH

Capacitance

Line to Line 0.303 µF 0.303 µF

Line to Ground 0.011 µF 0.011 µF

Discharge Resistor 680 KΩ 680 KΩ

Wire the AC line filter within 0.25 meters of the drive. The

ground connection from the filter must be wired to solid

earth ground (resistance less than 500 ohms); not machine

ground. This is very important!

If the end-user is using a CE-approved motor, the correct

filter from Table 3 is all that is necessary to meet the

EMC directives listed herein.
