Exhibit “A”

In addition to EMI/RFI safeguards inherent in the DC3N

series’ design, external filtering is required.

Reliance Electric requires the Corcom® filters listed in

Table 4. If the exact 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.

Table 5. Corcom® Filters

to the Drrive Part Number

0 to 4 amps 6VV1

4.1 to 13 amps 20VV1

The filters in Table 5 must be wired to the AC 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!
