EMI
The switch
is vulnerable to external interface caused by capacity coupling, inductance coupling, electromagnetic wave
radiation, common impedance (including grounding system) coupling and conducting wires (including power cords,
signal and output wires). Therefore, the following points should be noted:

The AC power supplying system is the TN system. The single-phase three-wire socket with protecting grounding
must be used as the socket for the power supply to enable the device’s upper filter circuit to effective filter the
power interface.
 The switch
should be far from high-power radio transmitting stations, radar stations and high-frequency and
large-current devices.

Electromagnetic shielding methods should be applied when necessary, such as using the shielded cable as the
interface cable.

Cables must be connected to interfaces inside the room to prevent damage to the device’s signal ports caused by
over-voltage and over-current generated by thunder and lightning.
System Grounding Requirements
A good grounding system is the basis for the stable and reliable operation of the RG-S5750-S series, preventing
lightning stroke and resisting 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.
The building must provide protective grounding connection to ensure that the device is connected to the
protection location.
The installation and maintenance personnel must check whether the A.C. socket is well connected to the
protection location of the building, if not, they should use a protective grounding wire to connect the
grounding end of the A.C. socket to the building's protection location.
The power supply socket must be installed in a place that is near to the device and where users can
operate the device easily.
