Installation Precautions
Note: To avoid damage to the equipment and personal injury caused by improper use,
please observe the following precautions.
safety precautions
❖ power supply remains off during the installation process. Wear an ESD-preventive wrist strap
and ensure that the ESD-preventive wrist strap is in good contact with the skin to avoid
potential safety hazards.
❖ Switch only can work normally under the correct power supply. Please confirm that the
power supply voltage matches the voltage indicated by the switch.
❖ Before powering on the switch, please make sure that the power circuit is not overloaded, so
as not to affect the normal operation of the switch and cause unnecessary damage.
❖ To avoid the risk of electric shock, do not open the case while the switch is working, even if
it is not charged, do not open it yourself;
❖ Before cleaning the switch, first pull out the power plug of the switch. Do not wipe with a
moist fabric. Do not use liquid to clean.
humidity
In order to ensure long-term stable operation of the switch and prolong its service life, please
maintain a certain temperature and humidity in the environment. Too high or too low ambient
humidity is likely to cause leakage, deformation and even corrosion of metal parts. If the temperature
is too high, the aging process of the insulation material will be accelerated, which will seriously
affect the service life of the equipment. The normal operation and storage temperature / humidity
of this series of switches are as follows:
