Appendix A – ACS/ACC/ACP 601 Technical DataACS/ACC/ACP 601 Frequency ConvertersA-27Public Low-VoltageNetwork1. The ACx 600 is equipped with EMC filtering (refer to Table A-1).2. The ACx 601 is installed with motor and control cables as specified in thismanual.3. Maximum cable length is 100 metres.Without considering the EMC requirements, do not use the ACx 600 on a low voltagepublic network supplying domestic premises. This kind of use might cause radiofrequency interference.Unearthed Mains(IT Network)1. It is ensured that no excessive emission is propagated to neighbouring low-voltage networks. In some cases, the natural suppression in transformers andcables is sufficient. If in doubt, the supply transformer with static screeningbetween the primary and secondary windings can be used.2. The ACx 601 is installed with motor and control cables as specified in thismanual.Note: The ACx 600 must not be equipped with EMC filtering (refer to Table A-1) wheninstalled to floating networks. The mains becomes connected to earth potential throughthe EMC filter capacitors. In floating networks this may cause danger or damage theunit.Machinery Directive ACx 601/604/607 frequency converters comply with the European Union MachineryDirective (89/392/EEC) requirements for an equipment intended to be incorporated intomachinery.UL/CSA Markings The UL/UL C /CSA markings of the ACS 600 frequency converters are listed below (x).1) the approval is valid up to 600 VUL ACS 600 is suitable for use in a circuit capable of delivering not more than 65 kA rmssymmetrical amperes at 480 V maximum (500 V units), and at 600 V maximum (690 Vunits).ACS 600 provides overload protection in accordance with the National Electrical Code(US). SeeACS 600 Firmware Manual for setting. Default setting is off, must beactivated at start-up.ACS 600 drives are to be used in a heated indoor controlled environment. SeesubsectionAmbient Conditions for specific limits.ACS 600 brake chopper - ABB has brake chopper modules that, when applied withappropriately sized braking resistors, will allow the drive to dissipate regenerativeenergy (normally associated with quickly decelerating a motor). Proper application ofthe brake chopper is defined in the Brake Chopper Installation Manual (NBRA-6xx;Braking Choppers Installation and Start Up Guide), Appendix A. These guide lines willallow you to size brake choppers to your specific application needs for standard orextended duty cycles. This can be applied to a single drive or multiple drives with DCBus connected to allow a sharing of regenerative energy.ACx 600 Type UL UL C CSAACS 601 (IP 22)480 V, 500 V and 600 1) V rangesx x xACS 601 (IP 54) x x xACS 604 frame sizes R7 to R9480 V, 500 V and 600 1) V rangesx x xACS 604600 V parallel connected unitspending pending pending
