USB端口
•在加拿大，所有接线必须符合《加拿大电气规范》第18-1J2节的规定，并符合具有管辖权的当局的规定对于欧洲2区和IECEx应用：–在应用中提供瞬态限制，将瞬态过电压限制为不超过施加电压的40%。–非显示计算机必须安装在污染等级为2的环境中，并完全安装在防护等级至少为IP54的外壳内除非已知该区域无危险，否则不要使用USB端口。•对于欧洲2区（气体）和IECEx应用，带有显示器的计算机必须安装在污染等级为2的环境中，并通过防护等级至少为IP54的外壳的墙壁或门安装对于欧洲22区（粉尘）和IECEx应用，带有显示器的计算机必须安装在污染等级为2的环境中，并通过防护等级至少为IP6x的外壳的墙壁或门安装。显示器支持外壳防护等级高达IP66的计算机。
设备正确接地
在最终应用中，使用计算机机箱上的接地端子螺钉将这些设备正确接地。注意：当温度高于50°C（122°F）时，显示计算机和整个非显示计算机的背面必须安装在受限的访问位置。6危险场所的工业计算机自动化出版物6181X-IN001D-EN-P-2015年7月I类2区和2区所需电路参数的USB外围设备控制图根据国家电气规范第500条（I类2区域IIB组和I类2分区A、B、C和D组）提供以下控制图。每个主机USB端口的参数值参数定义Voc（USB）5.25V DC开路电压。每个外围设备的最大施加额定电压Vmax（外围设备）应大于或等于Voc（USB）。
USB port
• In Canada, all wiring must comply with the Canadian Electrical Code, Section 18-1J2, and with the regulations of the authorities having jurisdiction. For European Zone 2 and IECEx applications: – Provide transient limits in applications that limit transient overvoltages to no more than 40% of the applied voltage. – The non display computer must be installed in an environment with a pollution level of 2 and completely installed in an enclosure with a protection level of at least IP54. Unless it is known that there is no danger in this area, do not use the USB port. • For European Zone 2 (gas) and IECEx applications, the computer with the display must be installed in an environment with a pollution level of 2 and installed through the wall or door of an enclosure with a protection level of at least IP54. For European Zone 22 (dust) and IECEx applications, the computer with the display must be installed in an environment with a pollution level of 2 and installed through the wall or door of an enclosure with a protection level of at least IP6x. The monitor supports computers with enclosure protection up to IP66.
Equipment is properly grounded
In the final application, use the grounding terminal screw on the computer chassis to properly ground these devices. Note: When the temperature is higher than 50 ° C (122 ° F), the back of the display computer and the entire non display computer must be installed in a restricted access location. 6 Industrial computer automation publication 6181X-IN001D-EN-P-2015 July, Class I, Zone 2 and USB peripheral equipment control diagram for circuit parameters required in Zone 2 and Zone 2 provide the following control diagram according to Article 500 of the National Electrical Code (Group IIB of Class I, Zone 2 and Groups A, B, C and D of Class I, Zone 2). The parameter value of each host USB port defines the Voc (USB) 5.25V DC open circuit voltage. The maximum applied rated voltage Vmax (peripheral device) of each peripheral device shall be greater than or equal to Voc (USB).
