31C005-503-4-00 SEW 电磁兼容限值

【产品详情】

●只使用原装Co连接元件!

观察MOVITRACE 31C电源端子的拧紧力矩:

尺寸0→15 Nm(13.3 ibin)/尺寸1 - + 0.6 Nm(5.3 ibin)/

尺寸2→15纳米(13.3磅英寸)/尺寸3和4 - + 3.5纳米(31磅英寸)

●设备有最小的通风空间(足够的冷却)!我留下一个最小值

设备上下间隙为100mm(4英寸)。不需要横向清除。

●机组必须垂直安装。其他安装位置是不允许的!

●MOVITRAC tec31c是专为在高压电力系统上运行而设计的

中性点接地(TN和TT电力系统)。

但是，在中性点不接地的高压电力系统上运行(例如:高压电源)

电力系统)也是允许的。SEW建议使用具有脉冲信号的大地测量仪

中性点不接地的电压系统(IT系统)的电压测量。这前

防止逆变器的接地电流无意中触发漏电

tor。干扰发射的电磁兼容限值没有对电压系统进行规定

非接地中性点(IT电源系统)。线滤波器的有效性是非常有限的。

●在一个主电源上有四个以上的单元，对所有单元的总电流进行预估

单元:串联一个三相e线扼流圈以限制浪涌电流。

电力电缆和电子电缆在不同的电缆管道中运行。

Ma - ins功率互感器:基于额定负载下的输入额定电流(数据→秒)。5)。

●PE市电连接(- EN 50178):如果PE导体的横截面< 10mm2 (AWG8)，则a

第二:与主电缆横截面相连接的离子电缆必须与PE平行运行

导体通过单独的端子或铜PE导体，横截面为10mm2

(AWG8)必须使用。市电接线≥10mm2 (AWG8)时，采用铜PE导线

必须使用与主接头横截面一致的连接电缆。在0操作过程中，我们会遇到一些麻烦

电流可以大于3.5 mA。

●电机电缆:根据输出额定电流IN(数据-→秒)5)。

输入熔断器必须安装在电源线的开头，直接在母线之后

结。(- +第2.8.1节:F11/F12/F1 3).使用D、DO、NH型保险丝或电源断路器。

●接地漏电断路器不允许作为唯一的漏电保护装置

在逆变器正常工作时，电流大于3.5 mA。

●从一个变频器交替操作两个电机:必须提供转换接触器

对于两个电机中的每一个都有电缆。变换接触器只能在

逆变器被禁用!

【英文介绍】

●Use only original Co nnection components!

Observe the tighteni ng torques of the MOVITRACE 31C power terminals:

Size0→15 Nm(13.3 Ib.in)/ Size1 - + 0.6 Nm (5.3 Ib.in)/

Size2→15 Nm (13.3 lb.in)/ Sizes3and4 - + 3.5 Nm (31 lb.in)

●Obs erve mini mum re qui re d venti| ation space of units (sufficient cooling)!  L eave a minimum

clearance of 100 mm (4 in) above an d below the unit.  No lat eral clearance required.

●Units must be mounted vertically.  0ther mounting positions are not p ermissible!

●The MOVITRAC园31C is designed for operation on voltage power systems with a directly

earthed neutral point (TN and TT powe r systems).

However, operation on vo ta ge power systems with a non-earthed neutral point (for examplelT

power syste ms) is also permitted.  SEW recomm ends using earth-lea ka ge monitors with pulse-

co de m ea surement in volta ge systems with non-earthed neutral points (IT systems).  This pre-

vents the earth ca pa citance of the inverter from inadvertently triggering the ea rthleakage mo ni-

tor.  The EMC limit va lues for interference emission are not specified for volta ge systems with a

non-ea rthed neutral point (IT power systems).  Line filter effectiven ess is extrem ely limited.

●With more than four units on a single mains Co nta ctor dim ensioned for the total current of all

units: connect a 3-phas e line choke in series to limit the inrush current.

Run power cabl es and ele ctronic lea ds in separate cable ducts.

Ma ins power cCa ble: based on input rated current lin at rated load (Data →Sec.  5).

●PE mains connection(-》EN 50178): If cross-section of PE conductor is < 10 mm2 (AWG8), a

second | ea d with the cross-section of the ma ins co nnect ion cable must be run parallel to the PE

conductor via separate terminals or a copper PE conductor with a cross-section of 10 mm2

(AWG8) must be used.  If the mains connection cable is≥10 mm2 (AWG8), a copper PE conduc-

tor with the cro ss-section of the ma ins conn ection cable must be used.  During 0 peration |ea ka ge

currents> 3.5 mA can occur.

●Motor cable: ba sed on the output rated current IN(Data- →Sec.  5).

The input fuses must be installed at the beginning of the power cable, directly after the busbar

junction.  (- + Sec. 2.8.1:F11/F12/F1 3). Use fuse types D, DO, NH or power circuit br eakers.

●An earth leakage circui-breaker is not permissible as the sole protection device, as leakage

currents > 3.5 mA can occur during normal invert er operation.

●Altern ate operation of two motors from one inve rter: a changeover contactor must be provided

for each of the two motors ca bles.  Changeove I contactors may only be actuated when the

inverter is disabled!
