VMIVME-9064工控备件模块
负载共享模块
一般布线要求圈出的接地符号表示保护接地端子。该端子必须使用至少与端子1至9上使用的接地导线一样大的接地导体直接连接到保护接地。接地导体的绝缘必须为绿色和黄色。此符号表示功能接地或EMC接地。该端子仅用于电缆屏蔽连接。不得用作保护接地端子。典型安装的外部接线连接和屏蔽要求如图1-3所示。本章将对这些接线连接和防护要求进行更详细的说明。为了保持符合CE标志要求，《低压指令》要求负载共享模块只能连接到III类设备。负载分配模块的接线必须至少适用于90°C（194°F），并且也适用于最大安装工作温度。负载共享模块必须永久连接，并在每个PT线路中使用保险丝或断路器，以限制 输入的电流不超过
所有接线板螺钉必须拧紧至0.56至0.79 N·m（5.0至7.0 lb in）。为了保持符合CE标志要求，EMC指令要求所有屏蔽都连接到根据工厂接线图（图1-3）提供的端子。电源要求负载共享模块由电压互感器连接供电。跳线用于为发电机产生的电压设置模块。当发电机产生95至130 Vac时，跨接端子15至16和17至18。当发电机产生190至260 Vac时，跨接端子16至17。电压互感器负荷为每相1.6W（230Vac输入）和每相0.4W（115Vac输入）。警告-仅限UMPERS仅对端子15至18进行跨接连接。不要对这些端子进行任何电气连接。该装置带有端子15–16和17–18，用于95至130伏的发电。要更改为190–260伏电压，请拆下两个跳线，并将其中一个跳线安装在端子16–17之间。然后不使用另一个跳线。
Load sharing module
The grounding symbol circled in general wiring requirements represents the protective grounding terminal. The terminal must be directly connected to the protective ground using a grounding conductor at least as large as the grounding conductor used on terminals 1 to 9. The insulation of the grounding conductor must be green and yellow. This symbol indicates functional ground or EMC ground. This terminal is only used for cable shield connection. It shall not be used as a protective grounding terminal. The external wiring connection and shielding requirements for a typical installation are shown in Figure 1-3. This chapter will describe these wiring connection and protection requirements in more detail. In order to maintain compliance with the CE marking requirements, the Low Voltage Directive requires that load sharing modules can only be connected to Class III equipment. The wiring of the load sharing module must be suitable for at least 90 ° C (194 ° F) and also for the maximum installation operating temperature. The load sharing module must be permanently connected and use fuses or circuit breakers in each PT line to limit the input current to no more than
All terminal block screws must be tightened to 0.56 to 0.79 N · m (5.0 to 7.0 lb in). In order to maintain compliance with the CE marking requirements, the EMC directive requires that all shields be connected to the terminals provided according to the factory wiring diagram (Figure 1-3). The power supply requires that the load sharing module is powered by the voltage transformer connection. Jumpers are used to set the module for the voltage generated by the generator. When the generator produces 95 to 130 Vac, jumper terminals 15 to 16 and 17 to 18. When the generator produces 190 to 260 Vac, jumper terminals 16 to 17. The voltage transformer load is 1.6W per phase (230Vac input) and 0.4W per phase (115Vac input). Warning - UMPERS only jumper terminals 15 to 18. Do not make any electrical connections to these terminals. The unit has terminals 15 – 16 and 17 – 18 for generating 95 to 130 volts. To change to 190 – 260 volts, remove the two jumpers and install one jumper between terminals 16 – 17. Then do not use another jumper.
