Installation
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 motor and
encoder feedback cables (maximum cable length of 10m), is all that is necessary to meet the EMC directives
listed herein. The end user must use the compatible filter to comply with CE specifications. The OEM may
choose to provide alternative filtering that encompasses the PositionServo drive and other electronics within
the same panel. The OEM has this liberty because CE requirements are for the total system.
3.4 Heat Sinking
The PositionServo drive contains sufficient heat sinking within the specified ambient operating temperature
in its basic configuration. There is no need for additional heat sinking. However, the user must ensure that
there is sufficient clearance for proper air circulation. As a minimum, an air gap of 25 mm above and below
the drive is necessary.
3.5 Line (Mains) Fusing
External line fuses must be installed on all PositionServo drives. Connect the external line fuse in series with
the AC line voltage input. Use fast-acting fuses rated for 250 VAC or 600 VAC (depending on model), and
approximately 200% of the maximum RMS phase current. Refer to section 2.3 for fuse recommendations.
