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.
