45 CE Compliance
Table 3. Corcom® Filters
Nameplate Current of
Motor Wired to the Drive Corcom ® Filter Part Number
0 to 4 amps 6VV1
4.1 to 13 amps 20VV1
The filters in Table 3 should be wired to the AC line 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!
Armature Filters
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.
If the end-user is not using a CE-approved motor, a Reliance Electric
CEXXRG filter must be deployed on the output. XX is the rated current
on the filter
The CE20RG is a Real-Pole Balanced-Pi 3-pole filter. If the exact filter is
not available, the specifications are as follows:
L & L1 = 2 * (0.8) milliHenries.
C & C1 = 2 * (0.1) microFarads @ 400W VDC.
Rin = 0.1 ohm; Rout = 1.2 ohm.

The filters in Table 2 must be wired to the DC output of the drive, as close
to the drive as possible. 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!
The end user must use the filtration listed in Exhibit A to comply with CE.
The OEM may choose to provide alternative filtering that encompasses the
Reliance drive and other electronics within the same panel.
