F-3 Technical SpecificationsAC30 series Variable Speed DriveSafetyOvervoltage Category Overvoltage Category III (numeral defining an impulse withstand level)Pollution Degree Pollution Degree II (non-conductive pollution, except for temporary condensation) for control electronicsPollution Degree III (dirty air rating) for through-panel mounted partsNorth America/Canada Complies with the requirements of UL508C as an open-type drive.EARTHING/SAFETY DETAILSEarthing Permanent earthing is mandatory on all units. Use a copper protective earth conductor 10mm² minimum cross-section, or install a second conductor in parallel with theprotective conductor to a separate protective earth terminal The conductor itself must meet local requirements for a protective earth conductorInput Supply Details(TN) and (IT)Drives without filters are suitable for earth referenced (TN) or non-earth referenced (IT) supplies.The drive is only suitable for earth referenced supplies (TN) when fitted with an internal filter. External filters are available for useon TN and IT (non-earth referenced) supplies.Prospective Short CircuitCurrent (PSCC)Refer to the appropriate Electrical Ratings table.Earth Leakage Current >10mA (all models)COOLING FANSThe forced-vent cooling of the drive is achieved by 1, 2 or in some cases 3 fans. The Fan Rating gives the volume of air venting from the drive per fan.Product Main Cooling Fan Ratings Internal Cooling Fan RatingsFRAME D Above 2.2kW only 1 off 27 cfm (45m³/hr)FRAME E All models 1 off 33 cfm (56m³/hr)FRAME F All models 2 off 27 cfm (45m³/hr)FRAME G All models 2 off 53 cfm (89 m³/hr) 1 off 27 cfm (45 m³/hr)FRAME H 45kW 2 off 27 cfm (45 m³/hr) 1 off 27 cfm (45 m³/hr)55 – 75kW 2 off 53 cfm (89 m³/hr)FRAME J All Models 3 off 80 cfm (133 m³/hr) 2 off 27 cfm (45 m³/hr)FRAME K All models 1 off 518 cfm (880 m³/hr)
