There are 2 ways to shield the cable for the acceleration sensors:
有两种方法可以对加速度传感器的电缆做屏蔽:
•Shielding possibilities on the terminal block. (Contact "Acc. sensor 1 - 4 shield")
•使用接线端子上的屏蔽(连接 1~4 通道的加速度传感器的屏蔽)
•X20 shielding on the bus module. (See the "Shielding" section in the X20 system user's manual)
•总线模块上的X20屏蔽(请参阅 X20 系统用户手册中的“屏蔽”部分)
Shielding via the terminal block is perfectly sufficient for environments with no special EMC requirements.
However, if the module is used in an environment with special EMC requirements and high frequency disturbances, both options should be used together.
对于没有特殊EMC要求的环境来说,通过接线端子进行屏蔽已经足够了。
但是,如果模块在具有特殊EMC要求和高频干扰的环境中使用,则应同时使用这两个选项。
