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 cables, 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 940 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 940 drive contains sufficient heat sinking within the specified ambient
operating temperature in their basic configuration. There is no need for additional heat
sinking. However, you must ensure that there is sufficient clearance for proper air
circulation. As a minimum, you must allow an air gap of 25 mm above and below the
drive.
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.

(1)
Installations with high fault current due to large supply mains may require a type D circuit breaker.
(2)
UL Class CC or T fast-acting current-limiting type fuses, 200,000 AIC, preferred. Bussman KTK-R, JJN, JJS or equivalent.
(3)
Thermal-magnetic type breakers preferred.
(4)
DC-rated fuses, rated for the applied voltage. Examples Bussman KTM or JJN as appropriate.
