在这种类型的系统中，一半的多用途电源必须连接到一个电源，另一半必须连接到单独的电源。这种布置提供了如上所述的基本冗余系统的所有优点以及电源冗余。只要最小数量的单元保持通电，前面板开关可用于移除单个电源。PACSystems*RX3i系统手册第5节GFK-2314T 2019年9月电源97多用途电源多用途电源开关设备图82：电源冗余连接4.3浮动中性点（IT）系统的交流电源连接如果交流输入电源安装在中性线未参考保护接地的系统中，必须遵循特殊安装说明，以防止电源损坏。浮动中性点系统是一种配电布线系统，其中中性点和保护接地不通过可忽略的阻抗连接在一起。在欧洲，这被称为IT系统（参考IEC950）。在浮动中性点系统中，从输入端子到保护接地测量的电压可能超过264Vac最大输入电压电源规格。L1 N PE图83：浮动中性线4.3.1浮动中性线系统的特殊说明输入电源端子应根据第2.6.6.1节“电源现场接线”中的说明进行接线，以下情况除外。1） 对于IC695电源，端子5或6与端子7之间不得安装跳线。2） 对于IC694和IC693电源，电源模块的端子3和4之间不得安装跳线。3） 必须安装电压浪涌保护装置，如MOV：▪ 从L1到接地▪ 从L2（中性点）到接地电压浪涌装置的额定值必须确保系统免受超过线路电压+100V+（N-PE）MAX的电力线瞬变的影响。N-PE表示中性点和保护接地（PE）之间的电压电势。例如在中性点浮置在地上50 Vac的240伏AC系统中，瞬态保护的额定值应为：PACSystems*RX3i系统手册第5节GFK-2314T 2019年9月电源98 240 Vac+100 Vac+50 Vac=390 Vac 4.3.2非浮动中性点系统系统，其中配电线路的一条腿连接到保护接地，或配电线路的两条腿之间的抽头连接到保护性接地系统。非浮动中性系统不需要特殊的安装程序。图84：非浮动中性线L1 N PE L N/PE L1 PE L2 PACSystems*RX3i系统手册第5节GFK-2314T 2019年9月电源99 4.4电源，120/240 Vac或125Vdc，40 W：IC695PSA040电源IC695PS040是一个40瓦电源，从85至264Vac或100 Vdc至300 Vdc的输入电压源工作。该电源提供三个输出：▪ +5.1Vdc输出，▪ +24Vdc继电器输出，可用于为输出继电器模块上的电路供电。▪ +3.3Vdc。此输出由具有IC695目录号的RX3i模块内部使用。警告：PACSystems RX3i（IC695产品目录号）通用背板中只能使用一个IC695PSA040。此电源不能与冗余或增加容量模式下的其他RX3i电源一起使用。如果不小心将IC695PSA040C或更早版本的电源安装在与另一个RX3i电源相同的背板中，可能会导致设备损坏。如果所需的模块数量超过电源的容量，
In this type of system, half of the Multi-purpose power supplies must be connected to one power source and the other half must be connected to a separate source. This arrangement provides all the advantage of a Basic Redundancy system, as described above, plus power source redundancy. The front panel switch may be used to remove an individual power supply as long as the minimum number of units remains powered up.

A Floating Neutral System is a system of power distribution wiring where Neutral and Protective Earth Ground are not tied together by negligible impedance. In Europe, this is referred to as an IT system (refer to IEC950). In a Floating Neutral System, voltages measured from input terminals to protective earth ground may exceed the 264Vac maximum input voltage power supply specification. L1 N PE Figure 83: Floating Neutral 4.3.1 Special Instructions for Floating Neutral Systems The input power terminals should be wired according to the instructions in Power Supply Field Wiring, Section 2.6.6.1 with the following exceptions. 1) For IC695 power supplies, no jumper may be installed between terminal 5 or 6 and terminal 7. 2) For IC694 and IC693 power supplies, no jumper may be installed between terminals 3 and 4 of the power supply module. 3) Voltage surge protection devices such as MOVs must be installed: ▪ From L1 to earth ground ▪ From L2 (Neutral) to earth ground The voltage surge devices must be rated such that the system is protected from power line transients that exceed Line voltage + 100V + (N-PE)MAX. The expression N-PE refers to the voltage potential between neutral and Protective Earth (PE) ground. For example, in a 240 Volt AC system with neutral floating 50 Vac above earth ground, the transient protection should be rated at: PACSystems* RX3i System Manual Section 5 GFK-2314T Sept. 2019 Power Supplies 98 240 Vac + 100 Vac + 50 Vac = 390 Vac 4.3.2 Non-Floating Neutral System Systems where one leg of the power distribution wiring is tied to Protective Earth or a tap between two legs of the power distribution wiring is tied to Protective Earth are not Floating Neutral Systems. Non-floating neutral systems do not require special installation procedures.

This power supply provides three outputs: ▪ +5.1Vdc output, ▪ +24Vdc relay output that can be used to power circuits on Output Relay modules. ▪ +3.3Vdc. This output is used internally by RX3i modules with IC695 catalog numbers. CAUTION Only one IC695PSA040 can be used in a PACSystems RX3i (IC695 catalog number) Universal Backplane. This power supply cannot be used with other RX3i power supplies in redundant or increased capacity modes. Power supply version IC695PSA040C or earlier may cause equipment damage if inadvertently installed in the same backplane as another RX3i power supply. If the number of modules required exceeds the capacity of the power supply,
