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.

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.
