Chapter 2 Installation
2.1 Preventive and Cautionary Tips
Before installation, put on anti-static gloves.
During the installation, power off your switch.
Use the attached power adapter or power cord to connect the switch to power supply.
The input voltage range must be consistent with the voltage range of the power adapter and
switch.
Ensure the switch is installed in a well-ventilated position.
Do not open or dismantle the shell of the switch.
Cut off power supply before cleaning the switch. Do not clean the switch with any liquid.
Keep the switch away from power line, electric light, and power grid.
2.2 Working Environment Requirements
2.2.1 Temperature and Humidity
In order to ensure normal working and operation life of the switch, room temperature and
humidity must be kept at certain level.
If room humidity is too high for a long time, insulating materials may be ineffective or even
lead to electricity leakage, mechanical performance of materials may change, and metal
components may be rust, etc.
If relative humidity is too low in the room, insulating gaskets may shrink, which leads to the
loosening of screws and static electricity, and damages circuit of your switch.
If room temperature is too high for a long time, insulating materials may be aging in a fast
speed, which substantially reduces the reliability of your switch and seriously impacts its
operation life.
2.2.2 Static Electricity Protection
Dust may lead to electrostatic adsorption. To protect the device from static electricity harm, pay
attention to the following requirements:
Keep the environment air clean. A regular dusting is necessary.
Make sure the device is grounded well.
