System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S8614/S8610/S8606/S8606 B. It is
the key to prevent lightning strike and resist interference. Please carefully check the grounding conditions on the
installation site according to the grounding requirements, and perform grounding properly as needed.
Safety Grounding
The equipment using AC power supply must be grounded by using the orange/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.
Lightning Grounding
The lightning protection system of the facility is a separate system that consists of the lightning rod, conductor and the
connector to the grounding system, which usually shares the power reference ground and orange/green safety cable
ground. The lightning discharge ground is for the facility only, irrelevant to the equipment. For the switch lighting protection,
refer to Appendix C.
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 1 ohm.
The RG-S8614/S8610/S8606/S8606 B chassis is installed with one grounding pole for shell protection which is required to
connect the grounding pole of the cabinet, as shown in Figure 2-10.

EMI Consideration
Various interference sources, from either outside or inside the equipment or application system, affect the system in the
conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation. There are two types of
electromagnetic interferences: radiated interference and conducted interference, depending on the type of the
propagation path. When the energy, often RF energy, from a component arrives at a sensitive component via the space,
the energy is known as radiated interference. The interference source can be both a part of the interfered system and a
completely electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable
connection between the source and the sensitive component, along the cable the interference conducts from one unit to
another. Conducted interference often affects the power supply of the equipment, but can be controlled by a filter.
Radiated interference may affect any signal path in the equipment, and is difficult to shield.
To ensure that the equipment works properly, you must connect cables properly. Before you connect the cables, please
carefully read the following precautions.
Effective measures should be taken for the power system to prevent the interference from the electric grid.
