RG-S2600G-I Series Switch Hardware Installation and Reference Guide
The
Average
refers to the average limit of harmful gas in one week. The
Maximum
value is the upper limit of
the harmful gas measured in one week for up to 30 minutes every day.
EMI
During applications, the switch may be subject to external interferences that affect the device through conduction manners
such as capacitance coupling, inductive coupling, electromagnetic wave emission, common impedance (including
grounding systems), and wires (power cables, signal cables and outgoing transmission cables). For that purpose, note
that:
For the AC power supply system TN, single-phase three-core power socket with protective earthing conductors (PE)
should be adopted to effectively filter out interference from the power grid through the filtering circuit.
The switch should be located at places free from large power radio launch pad, radar launch pad, and
high-frequency large-current devices.
If necessary, electromagnetic shielding should be adopted. For example, use interface cables to shield cables.
Interface cables should be laid inside the equipment room. Outdoor cabling is prohibited, avoiding damages to
device signal interfaces caused by over-voltage or over-current of lightning.
System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S2600G-I series. 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.
The correct connection of grounding lines guarantees the lighting and interference resistance of switches
and must be performed with precision.
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.
Lightning Grounding
The lightning protection system of a facility is an independent system that consists of the lightning rod, downlead
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.
