Clearness Requirements
It is required that there are no explosive, conductive, magnetic, and corrosive dusts in the install-
ation site. The dust concentration requirement in the equipment room is shown as below:
Mechanically
Active Sub-
stance
Unit Concentration
Dust Particle Particles/m
3
≤3×10
4
(No visible dust on tables within 3
days)
Note: Diameter of dust particle ≥5μm
ESD Prevention
To prevent electrostatic discharge (ESD) damage, ensure that:
l
The device is well grounded. The grounding screw is properly grounded.
l
Take dustproof measures for the equipment room.
l
Maintain proper humidity and temperature levels.
l
Do not disassemble the device without permission from the vendor, or you may cause danger
and void your warranty.
EMI Prevention
All possible Electromagnetic Interference (EMI) sources, external or internal, affect the device in
the way of capacitance coupling, inductance coupling, electromagnetic radiation, and common
impedance (including the grounding system) coupling. To prevent or reduce EMI:
l
Take measures to protect the power system from the interference of the power grid.
l
Separate the protection ground of the device from the grounding device or lighting protection
grounding device of the power supply equipment as far as possible.
