Please keep a proper temperature and humidity in the equipment room. Too high/
low humidity may lead to bad insulation, electricity leakage, mechanical property
changes and corrosions. Too high temperature may accelerate aging of the
insulation materials and can thus significantly shorten the service life of the device.
For normal temperature and humidity of the device, please check the following table.

Clearness
The dust accumulated on the switch can be absorbed by static electricity and
result in poor contact of metal contact points. Some measures have been taken for
the device to prevent static electricity, but too strong static electricity can cause
deadly damage to the electronic elements on the internal circuit board. To avoid
the effect of static electricity on the operation of the Switch, please attach much
importance to the following items:
■
Dust the device regularly, and keep the indoor air clean.
■
Keep the device well grounded and ensure static electricity has been transferred.
Electromagnetic Interference
Electronic elements including capacitance and inductance on the device can be
affected by external interferences, such as conducted emission by capacitance
coupling, inductance coupling, and impedance coupling. To decrease the
interferences, please make sure to take the following measures:
■
Use the power supply that can effectively filter interference from the power grid.
■
Keep the device far from high-frequency, strong-current devices, such as radio
transmitting station.
■
Use electromagnetic shielding when necessary.
