If there is no appropriate grounding point on the cabinet, we also can connect the
grounding cable of the router to other grounding bar of the installation place.
Fire hose and lightning rod grounding of the building are not the proper grounding
location; the grounding cable of the device should be connected to the engineering
grounding of the equipment room.
3.3 (Optional) Install SPD
3.3.1 Install AC Power SPD
The AC power SPD (surge protection device) suppresses the transient overvoltage caused by
lightning inductance shock or other reasons on the power transmission line. When a SPD is
used, the AC power first enters the SPD and then enters the device.
