power supply in case of an accident.
⚫ Be sure to make a careful check before you shut down the power supply.
⚫ Do not place the device in a damp/wet location. Do not let any liquid enter the device.
⚫ Keep the device far away from the grounding or lightning protection devices of power device.
⚫ Keep the device away from high-power radio stations, radar stations, and high-frequency high-current
devices.
2.2 Installation Environment Requirements
To ensure normal operation and a prolonged useful life of the device, the installation site must meet the
following requirements.
2.2.1 Environment Requirements
⚫ Install the device in a well-ventilated environment. If it is installed in a closed room, make sure there is a
good cooling system.
⚫ Make sure the site is sturdy enough to support the device and its accessories.
⚫ Make sure the site has enough space for installing the device and leave sufficient space around the device
for ventilation.
2.2.2 Ventilation Requirements
For proper ventilation, leave sufficient space around the device.
2.2.3 Temperature/Humidity Requirements
To ensure the normal operation and prolonged service life of the device, maintain an appropriate temperature
and humidity in the equipment room. The equipment room with too high or too low temperature and humidity for
a long period may damage the device.
⚫ In an environment with high relative humidity, the insulating material may have bad insulation or even leak
electricity and sometimes the materials may suffer from mechanical performance change and metallic parts
may get rusted.
⚫ In an environment with low relative humidity, the insulating strip may dry and shrink, and static electricity is
prone to occur and damage the internal circuits of the device. In an environment with high temperature, the
device is subjected to even greater harm, as its performance may degrade significantly and its useful life
may be shortened in the case of long-term exposure that expedites the aging process.
