When the fast rolling shutter door is connected to the power supply, the operator needs to carry out a series of inspections to confirm that the fast rolling shutter door can work normally. Now, industry is here to talk about the precautions for using fast rolling shutter doors.

1、不要在电源和快门开关之间安装接触器。一旦接触器安装好，就会影响快速滚动的快门变频器的使用寿命。

1. Do not install a contactor between the power supply and the shutter switch. Once the contactor is installed, it will affect the service life of the fast rolling shutter frequency converter.

2、电压，快速快门与逆变器的输入电压是一致的，如果单相220 v输入电压，电源电压220 v,如果逆变器三相电压380 v,供电电压是380 v。

2. Voltage, the fast shutter is consistent with the input voltage of the inverter. If the single-phase 220 V input voltage, the power supply voltage is 220 v. if the three-phase voltage of the inverter is 380 V, the power supply voltage is 380 v.

3、快速卷帘门的电气控制箱应安装在避免高温、潮湿、阳光直射和水汽的地方，避免电气控制箱中电器元件的损坏。

3. The electrical control box of the fast rolling shutter door shall be installed in a place that avoids high temperature, humidity, direct sunlight and water vapor, so as to avoid the damage of electrical components in the electrical control box.

4、高速门的输出端不应安装在空气中，也不应安装接触器等开关装置以避免变流器的故障和设备的损坏。如果您需要为流程和其他方面安装开关设备，您需要确保在切换时，逆变器不会输出。

4. The output end of high-speed door shall not be installed in the air, nor shall contactor and other switching devices be installed to avoid converter failure and equipment damage. If you need to install switchgear for processes and other aspects, you need to ensure that the inverter will not output during switching.

5、在快速卷绕门逆变器输入接触器之前，控制变频器启动或停止会影响变频器的使用寿命，因此，应注意转炉或转炉端子的控制。如果快速卷帘门安装在更高的频率上，应该特别注意这个问题。

5. Before the fast winding door inverter inputs the contactor, controlling the start or stop of the frequency converter will affect the service life of the frequency converter. Therefore, pay attention to the control of the converter or converter terminal. If the fast rolling shutter door is installed at a higher frequency, special attention should be paid to this problem.
