为了使本章中的描述简洁易懂尽可能可读，表格1、2…中的交叉引用习惯于一般转换器和设备的主要部分，构成直流驱动器不能独立满足EMC要求另外必须由熟练人员安装和连接
根据本手册中规定的指南。这一限制与EN 61800-3的简短描述中的“受限分布”相关，该描述是EMC产品标准动力驱动系统。接地线中的滤波器（TN或TT网络）过滤器仅适用于接地线，例如在公共场所欧洲400V线路。根据EN 61800-3，过滤器不在绝缘工业线路中与自己的电源变压器兼容
由于它们在这种浮动线路（IT网络）中的安全风险。接地故障检测
滤波器（带内部放电电阻器）、电缆、转换器并且电动机一起具有相当大的对地电容，这会导致电容性接地电流增加。绊倒测量该电流的接地故障检测器的阈值必须：以适应该较高值。高压试验由于线路滤波器的电容器，高压测试具有：用直流电压来保护组件。
警告线路滤波器包含电容器，可保持危险电压在电源电压断开后的端子处。内部电阻器的放电需要几秒钟。因此，之前必须至少等待10秒并进行电压检查你从设备开始工作。如果转换器应：在公共低压线路上运行，例如在欧洲，400 V
在相位之间。此类线路具有接地中性导线。ABB提供适用于400V和25伏的三相滤波器
A、 ..600 A和500 V滤波器，用于欧洲以外的440 V线路（见附录A）。
500V至1000V的线路不公开。它们是工厂内部的本地线路，不提供敏感电子产品。因此，如果转换器在500 V下运行，则不需要EMC滤波器以及更多（另见6）。
3个现场单相滤波器供给许多现场电源装置为单相转换器，高可达50 A励磁电流。它们可以由三个输入中的两个提供
电枢电源转换器的相位。然后是现场供电装置
不需要自己的过滤器，如连接示例所示(24).
如果中性导线的相电压应为（230 V在400V线路中），则需要一个单独的滤波器，如下所示。ABB为250V和6…55A提供此类滤波器（见附录A）。In order to make the description in this chapter as short and easily
readable as possible, cross references in the form 1 , 2 … are
used.
General Converters and the major part of the devices, which constitute a DC
Drive, cannot fulfil the EMC requirements independently from each
other. They must be installed and connected by skilled personnel
according to the guidelines laid down in this manual. This restriction
is related to the expression “restricted distribution” in the short description of EN 61800-3, which is the EMC product standard for a
Power Drive System.Filter in an earthed line (TN or TT Network)
The filters are suitable for earthed lines only, for example in public
European 400 V lines. According to EN 61800-3, filters are not
compatible in insulated industrial lines with own supply transformers
due to their safety risks in such floating lines (IT networks).
Earth fault detection
Filters (with internal discharging resistors), cables, the converter
and the motor have together a considerable capacitance to ground,
which can cause an increased capacitive earth current. The tripping
threshold of an earth fault detector that measures this current must
be adapted to this higher value.
High voltage test
Because of the capacitors of the line filter the high voltage test has
to be done with dc voltage to protect the components.
Warning
Line filters contain capacitors, which can keep dangerous voltages
at the terminals after the switch off of the mains voltage. The discharge by internal resistors takes some seconds. Therefore a waiting time of at least 10 s and a voltage check are obligatory before
you begin your work at the equipment.EMC filters are necessary to fulfil EN 50081 if a converter shall be
run at a public low voltage line, in Europe for example with 400 V
between the phases. Such lines have an earthed neutral conductor. ABB offers suitable three - phase filters for 400 V and 25
A...600 A and 500 V filters for 440 V lines outside Europe (see Appendix A).
Lines with 500 V to 1000 V are not public. They are local lines inside factories, and they do not supply sensitive electronics. Therefore converters do not need EMC filters if they shall run with 500 V
and more (see also 6).
3 Single-phase filters for field
supply
Many field supply units are single - phase converters for up to 50 A
excitation current. They can be supplied by two of the three input
phases of the armature supply converter. Then a field supply unit
does not need an own filter as shown at the connection example
(24).
If the phase voltage to the neutral conductor shall be taken (230 V
in a 400 V line) then a separate filter is necessary as shown below.
ABB offers such filters for 250 V and 6...55 A (see Appendix A).
