Appendix A – ACS/ACC/ACP 601 Technical Data
ACS/ACC/ACP 601 Frequency Converters A-27
Public Low-Voltage
Network
1. 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 this
manual.
3. Maximum cable length is 100 metres.
Without considering the EMC requirements, do not use the ACx 600 on a low voltage
public network supplying domestic premises. This kind of use might cause radio
frequency 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 and
cables is sufficient. If in doubt, the supply transformer with static screening
between the primary and secondary windings can be used.
2. The ACx 601 is installed with motor and control cables as specified in this
manual.
Note:
The ACx 600 must not be equipped with EMC filtering (refer to Table A-1) when
installed to floating networks. The mains becomes connected to earth potential through
the EMC filter capacitors. In floating networks this may cause danger or damage the
unit.
Machinery Directive
ACx 601/604/607 frequency converters comply with the European Union Machinery
Directive (89/392/EEC) requirements for an equipment intended to be incorporated into
machinery.
UL/CSA Markings

C
/CSA markings of the ACS 600 frequency converters are listed below (x).
1)
the approval is valid up to 600 V
UL
ACS 600 is suitable for use in a circuit capable of delivering not more than 65 kA rms
symmetrical amperes at 480 V maximum (500 V units), and at 600 V maximum (690 V
units).
ACS 600 provides overload protection in accordance with the National Electrical Code
(US). See
ACS 600 Firmware Manual
for setting. Default setting is off, must be
activated at start-up.
ACS 600 drives are to be used in a heated indoor controlled environment. See
subsection
Ambient Conditions
for specific limits.
ACS 600 brake chopper - ABB has brake chopper modules that, when applied with
appropriately sized braking resistors, will allow the drive to dissipate regenerative
energy (normally associated with quickly decelerating a motor). Proper application of
the brake chopper is defined in the Brake Chopper Installation Manual (NBRA-6xx;
Braking Choppers Installation and Start Up Guide), Appendix A. These guide lines will
allow you to size brake choppers to your specific application needs for standard or
extended duty cycles. This can be applied to a single drive or multiple drives with DC
Bus connected to allow a sharing of regenerative energy.
