SimpleServo 500/600/i1000 User Manual Rev 3.4
In order to comply with EN50081-1 and EN50082-2, the following filters must be installed within 20cm of
the drive power inputs:

1 For 3-phase (-3P) models
Line filters should be placed inside the shielded panel. Connect the filter to the incoming power lines
immediately after the safety mains and before any critical control components (Figure 6). Wire the AC line
filter as close as possible to the SimpleServo. If you add separate fuses, add them after the AC line filter.
Note
The ground connection from the filter must be wired to solid earth ground, not machine
ground.
If the end-user is using a CE-approved motor, the AC filter combined with the recommended SimpleServo
motor and encoder cables, is all that is necessary to meet the EMC directives listed herein. The end user
must use the comparable filter (see table above), to comply with CE specifications. The OEM may choose
to provide alternative filtering that encompasses the SimpleServo and other electronics within the same
panel. The OEM has this liberty because CE is a machinery directive.
4.6 Heat sinking
SimpleServos contain sufficient heat sinking in their basic configuration. There is no need for additional
heat sinking. However, drives that output more than 8 amps incorporate a heat sink cooling fan; you must
ensure that there is sufficient clearance for the cooling fan to circulate air (Figure 3). As a minimum, you
must allow an air gap of 1 inch above and below the drive.
4.7 Line fusing
External line fuses must be installed on all SimpleServos. Connect the external line fuse in series with the
AC line voltage input. Table 3 lists the recommended line fuse sizes. Use fast acting fuses rated for 250
VAC or higher, and approximately 200% of the maximum phase current.
