CE Compliance
Reliance Electric Corporation hereby certifies that its DC3N series drives have
been approved to bear the “CE” mark provided the conditions of approval have
been met by the end user.
The DC3N series has been tested to the following test specifications:
EN55011:1991 (emissions), and
EN50082-1:1992 (immunity)
Compliance allows Reliance Electric’s DC3N series to bear the
CE mark.
The end user, as described herein, falls into one of two categories:
1. The Consumer will deploy a stand-alone unit as an integral, yet external,
portion of the machine being operated.
2. The Original Equipment Manufacturer (OEM) will implement the product
as a component of the machine being manufactured.
External filtering
In addition to EMI/RFI safeguards inherent in the DC3N series’ design, external
filtering is required. If the end-user is using a CE-approved motor, the correct line
filter listed below is all that is necessary to meet the EMC directives listed herein.
Line filters
Reliance Electric requires the Corcom® line filters listed below.
Table 3. Corcom® Filters
Nameplate Current of Corcom® Filter
Motor Wired to the Drive Part Number
0 to 4 amps 6VV1
4.1 to 13 amps 20VV1
If the exact line filter is not available, the specifications are as follows:
L = (1.73 + 0.03) milliHenries.
C = (0.27 + 0.54) microFarads (X); 0.0055 microFarads (Y).
R = 330Kohms.
Rated current: 1.4 times maximum DC motor current.
Filter type: Balanced 2-section.
The line filters should be wired to the AC line within 0.25 meters of the drive. The
ground connection from the line filter must be wired to solid earth ground
(resistance less than 500 ohms); not machine ground. This is very important!
