VMIVME-9064工控備件模塊
負載共享模塊
一般布線要求圈出的接地符號表示保護接地端子。該端子必須使用至少與端子1至9上使用的接地導線一樣大的接地導體直接連接到保護接地。接地導體的絕緣必須為綠色和黃色。此符號表示功能接地或EMC接地。該端子僅用于電纜屏蔽連接。不得用作保護接地端子。典型安裝的外部接線連接和屏蔽要求如圖1-3所示。本章將對這些接線連接和防護要求進行更詳細的說明。為了保持符合CE標志要求,《低壓指令》要求負載共享模塊只能連接到III類設備。負載分配模塊的接線必須至少適用于90°C(194°F),并且也適用于最大安裝工作溫度。負載共享模塊必須永久連接,并在每個PT線路中使用保險絲或斷路器,以限制 輸入的電流不超過
所有接線板螺釘必須擰緊至0.56至0.79 N·m(5.0至7.0 lb in)。為了保持符合CE標志要求,EMC指令要求所有屏蔽都連接到根據工廠接線圖(圖1-3)提供的端子。電源要求負載共享模塊由電壓互感器連接供電。跳線用于為發電機產生的電壓設置模塊。當發電機產生95至130 Vac時,跨接端子15至16和17至18。當發電機產生190至260 Vac時,跨接端子16至17。電壓互感器負荷為每相1.6W(230Vac輸入)和每相0.4W(115Vac輸入)。警告-僅限UMPERS僅對端子15至18進行跨接連接。不要對這些端子進行任何電氣連接。該裝置帶有端子15–16和17–18,用于95至130伏的發電。要更改為190–260伏電壓,請拆下兩個跳線,并將其中一個跳線安裝在端子16–17之間。然后不使用另一個跳線。
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.
