Keep the equipment room as clean as possible.
Maintain adequate temperature and humidity.
Wear an ESD-preventive wrist strap and clothes when handling the circuit board.
2.2.4 Anti-interference requirement
All interference sources, wherever they are from, impact the switch negatively in the conducted
emission patterns of capacitance coupling, inductance coupling, electromagnetic wave radiation, and
common impedance (including the grounding system) coupling. To resist the interference, make sure
to:
The alternating power supply system is TN system. Adopt single-phase three wire socket with
protection ground wire to filter electricity power interference by the device filter circuit.
Keep the device far from strong the power radio launchers, radar launchers, and high frequency
and high-current equipment.
Use electromagnetic shielding when necessary, such as you can use shielded cable
Require you using interface cable indoors, not use it outdoors, to prevent overvoltage and over
electricity damaging the device by thunder.
2.2.5 Lightning protection
Although the switch is designed to be lightning resistant, your device can get damaged when excessive
lightning is present. To protect your device against lightning,
Ensure the chassis is connected to the earth ground.
Ensure the ground point of the power socket is well connected to the earth ground.
Add a lightning arrester onto the front end of the power input to better protect the power supply
from lightning strikes.
2.2.6 Grounding requirement
Reliable grounding system is the foundation of stable and reliable operation and is the important
guarantee for lightning protection, anti-interference and anti-static. You must provide a good grounding
system for your switch.
To see the detailed operation of device grounding, please refer to Figure3-6.
2.2.7 Wiring cable requirement
Cables connect the device should be indoors, not wiring outdoors. When you wiring indoors, you
should pay attention to the followings:
Do not wiring cables in working area, so that it can avoid the cables to be damaged or dropped
from ceiling.
