2.2.3 Anti-static Requirements
The router circuitry is designed with anti-static protection, but excessive static electricity may still damage router
circuit boards. The static electricity of the network connected with the routers comes largely from the following
sources:

Outdoor electric field produced by the high-voltage supply cable and lightning.

Indoor systems such as the indoor floor and the entire structure.
Therefore, the following requirements must be met:

Ensure proper grounding of the device and floor.

Prevent indoor dust.

Maintain proper temperature and humidity.

Wear ESD wrist straps and ESD lab coats when touching a circuit board.

Put the removed circuit board face up on an anti-static workbench or in an electromagnetic shielding bag.

Touch the external edge of the board and avoid touching the parts on the board directly with hands when
observing or carrying the detached circuit board.
2.2.4 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RSR20-X-28 and the key to prevent
lightning stroke and resist interference. Please carefully check the grounding conditions on the installation site
according to the grounding requirements, and perform grounding properly as needed.
2.2.5 Safety Grounding
The equipment using AC power supply must be grounded by using the yellow/green safety grounding cable.
Otherwise, when the insulating resistance decreases the power supply and the enclosure in the equipment, electric
shock may occur.
The building installation shall provide a means for connection to protective earth, and the equipment is to be
connected to that means.
2.2.6 EMC Grounding
The ground required for EMC design includes shielding ground, filter ground, noise and interference suppression,
and level reference. All the above constitute the comprehensive grounding requirements. The grounding resistance
should be less than 1Ω.
