42 CE Compliance
Armature filters
If the end-user is not using a CE-approved motor, a second
filter on the armature must be deployed. This filter will have the Reliance Electric
part number CEXXMM, where XX is the motor current rating listed on the
nameplate. Reliance Electric® Filters are listed below.
Table 4. Reliance Electric® Filters
Nameplate Current of Reliance Electric® Filter
Motor Wired to the Drive Part Number
0 to 4 amps CE4MM
4.1 to 13 amps CE20MM
The filters listed above are Real-Pole Balanced-Pi 3-pole
filters. 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 listed above must be wired to the DC output of the drive, as close to the
drive as possible.
The end user must use the filters listed in this section to comply with CE. The
OEM may choose to provide alternative filtering that encompasses the Reliance
Electric drive and other electronics within the same panel.
The OEM has this liberty because CE is a machinery directive. Whether or not
every component in the OEM’s machinery meets CE, the OEM must still submit
his machine for CE approval.
Thus, no component must necessarily meet CE within the machine, as long as the
OEM takes the necessary steps to guarantee the machine does meet CE. By the
same token, even if every component in the OEM’s machine does meet CE, the
machine will not necessarily meet CE as a machine.
Using CE-approved wiring practices (such as proper shielding) and the filters listed
in this section help the drive meet EN55011 (1991 emissions standard) and
EN50082-1 (1992 immunity standard).
