Available filters from Parker Hannifin:10 Amp filter—part number 47-016140-0116 Amp filter—part number 47-017900-01Table 60 Mains Filter Selection• Install transient suppressors. You must install varistors or other voltagesurge limiting devices in order to meet the requirements of EN61000-4-5. Place a Littelfuse V275LA2ØC, or an equivalent varistor, from line toline and from lines to earth before the mains filter, as shown in the EMCInstallation drawings. (Intersil, General Electric, and Littelfusemanufacture equivalent varistors.)• Use shielded cabling with braided and bonded headshells.Parker Hannifin EMC cabling—requires no additional cable preparation.The design of the ACR9000 controller D-sub connectors provides areliable earth bond when used with Parker EMC cabling. It requires noadditional cable screen earth bond if the chassis of the ACR9000 isadequately bonded to the system earth.For maximum immunity, both ends of each cable must be earth-bonded.All connections must be made using a high quality braided-screen cable(with minimum of 85% coverage). Cables using a metalized plasticbandage for an earth screen are unsuitable and in fact provide very littlescreening. Care must be taken when terminating the cable screen, asthe screen itself is comparatively fragile; bending it round a tight radiuscan seriously affect the screening performance. The selected cablemust have a temperature rating which is adequate for the expectedoperating temperature of the motor case.All cables must maintain high integrity 360-degree shielding. ParkerHannifin CE cables are fully shielded and provide the necessaryscreening. For differential signals (inputs and outputs), shielded,twisted-pair wiring (with 3 turns per inch (TPI)) is recommended. Whenyou install limit switches and other inputs/outputs, you must observethese noise immunity procedures and practices.• Route cables as shown in the EMC Installation drawing, Figure 27 onpage 96.Route high power cables (motor and mains) at right angles to low powercables (communications and inputs/outputs). Never route high and lowpower cables parallel to each other.
