安装设备
断电将模块安装在标准导轨上（接线盒和/或配电盘中符合IEC 60715的TH35）。安装电气安装和设备终端只能由合格人员进行，并遵守所有适用规范和法规。插入用于总线连接的端子板3 4 5 mm 5 6模块可以无间隙对齐。当模块串联安装时，使用跳线插头连接总线和电源电压。串联连接的最大模块数量限制为15个，或每次连接到电源的最大功耗为2安培（交流或直流）。对于任何类似的附加模块块，必须单独连接电源。连接总线电源的电缆，安装在系列7中。比特率和奇偶校验设置。当将转发器插入模块前盖后时，可以在编程模式下设置比特率和校验。此跳线在正常模式下拆下。比特率设置期间不需要连接到总线。模块的比特率可以通过以下方式设置：1.卸下模块的前盖；2.将跳线插入红色和绿色LED（a）之间的4极接头的两个中间引脚；3.根据下表，使用地址开关（-）设置所需的奇偶校验和比特率。4.打开模块的电源电压；它现在将比特率永久保存在EEPROM中；5.关闭模块的电源电压；6.从收割台上拆下跳线并放置前盖。如果设置与图表中指定的设置不同，则应用出厂设置。工厂设置：19200 Bd Eve

Installation equipment
Power off to mount the module on standard rails (TH35 according to IEC 60715 in junction boxes and/or distribution boards). The installation of electrical installations and equipment terminations must only be carried out by qualified personnel and in accordance with all applicable codes and regulations. The terminal block 3 4 5 mm 5 6 modules inserted for bus connection can be aligned without gaps. When the modules are installed in series, use jumper plugs to connect the bus and power supply voltage. The maximum number of modules connected in series is limited to 15, or the maximum power consumption per connection to the power supply is 2 amperes (AC or DC). For any similar add-on block, the power supply must be connected separately. The cable connecting the bus power supply is installed in series 7. Bit rate and parity settings. When the repeater is inserted behind the front cover of the module, the bit rate and parity can be set in the programming mode. This jumper is removed in normal mode. It is not necessary to connect to the bus during bit rate setting. The bit rate of the module can be set in the following ways: 1. Remove the front cover of the module; 2. Insert the jumper into the two middle pins of the 4-pole connector between the red and green LED (a); 3. Use the address switch (-) to set the required parity sum bit rate according to the following table. 4. Turn on the power supply voltage of the module; It now permanently stores the bit rate in EEPROM; 5. Turn off the power supply voltage of the module; 6. Remove the jumper from the header and place the front cover. If the settings are different from those specified in the chart, the factory settings are applied. Factory setting: 19200 Bd Eve
