Be sure to ground the chassis and workbench properly.
To guarantee long-term steady operation of the switches, the installation site also must meet
the following requirements:
Temperature and humidity
To guarantee normal operation and the service life of switches, the machine room must
maintain a certain temperature and humidity. Long-term high humidity in machine room is
liable to cause defective insulation and even electric leakage of insulating materials, and
changes in mechanical performance of materials and corrosion of metal parts at some time; in
the case of excessively low relative humidity, the fastening screws might become loose due to
air shrinkage of the insulating spacer, and static electricity is likely to be generated in dry
environment to harm the electric circuits of switches; excessively high temperature is more
harmful because long-term high temperature will accelerate the ageing of insulating materials
to lower the reliability of switches and largely reduce the service life.

Cleanliness
Dust is one of the threats to safe operation of switches. Dust falling onto the machine body
might cause electrostatic adhesion, to result in bad contact of metal connectors or metal
contacts. Particularly, low room relative humidity is more liable to cause electrostatic
adhesion, which will not only reduce the life of equipment, but also cause communication
failure.

Note: Dust particle diameter ≥5um
Besides dust, switches room is also subject to strict requirements for the content of salt, acid
and sulfide in the air. These harmful gases will accelerate corrosion of metals and the ageing
of some parts. Measures must be taken to prevent harmful gases such as SO2, H2S, NH3 and
Cl2 from intruding into the machine room.
