The average and maximum values are measured for a week. The switch cannot be placed in the environment with
the maximum density for over 30 minutes every day.
2.2.4 Interference Resistance
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, note the following points:
 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.
2.2.5 Grounding
A good grounding system is the basis for stable and reliable operation of the device, preventing lightning strokes and
resisting interference. Carefully check the grounding conditions at the installation site according to the grounding
requirements, and perform grounding operations properly as required.
Effective grounding of the switch guarantees surge protection and interference resistance. Therefore, connect the
grounding line of the switch properly.
Safety Grounding
The device 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 the 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, 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.
Before device installation, ensure that the ground is connected at first and disconnected finally.
