Apart from dust, the salt, acid and sulfide in the air in the equipment room must also meet strict requirements,
as such poisonous substances may accelerate the corrosion of the metal and the aging of some parts. The
equipment room should be protected from the intrusion of harmful gases such as sulfur dioxide, sulfured
hydrogen, nitrogen dioxide, and chlorine.

2.2.5 Grounding
A good grounding system is the basis for the stable and reliable operation of the RG-EG V2 series router. It is
the chief condition 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 operations
properly as required.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, download
conductor and the connector to the grounding system, which usually shares the power reference ground and
yellow/green safety cable ground. The lightning discharge ground is for the facility only, irrelevant to the
equipment.
2.2.6 EMI
Electro-Magnetic Interference (EMI), from either outside or inside the equipment or application system, affects
the system in the conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation.
There are two types of electromagnetic interference: radiated interference and conducted interference,
depending on the type of the transmission path.
