RG-IS2700G Series Switch Hardware Installation and Reference Guide
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.
2.3 System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-IS2700G 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.
2.3.1 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.
2.3.2 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.
2.3.3 EMC Grounding
The grounding 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 1 ohm. The side panel of 0RG-IS2700G is reserved with one grounding pole, as shown in 2-1.
