Make sure the installation site is flat, vibration-free, and away from electromagnetic
interferences. ESD-prevention and anti-slip measures are in place.
Keep the chassis and installation tools away from walk areas.
Do not place the device on an unstable case or desk. The device might be severely damaged in
case of a fall.
Keep the chassis clean and dust-free.
Do not place the device near water or in a damp environment. Prevent water or moisture from
entering the device chassis.
Remove all cables from the device before moving it.
Ensure good ventilation in the equipment room and make sure the air inlet and outlet vents of
the device are not blocked.
Make sure the power voltage for the device is in the acceptable range.
Use a screwdriver to fasten screws.
After you move the device from a location below 0°C (32°F) to the equipment room, wait a
minimum of half an hour before unpacking the device and a minimum of 2 hours before
powering on the device.
Electricity safety
Carefully examine your work area for possible hazards, such as moist floors, ungrounded
power sources, or missing safety grounds.
Locate the emergency power-off switch in the room before installation. Shut off the power
immediately if an accident occurs. Remove the power cord if necessary.
Do not work alone when you operate the device with power on.
Always verify that the power has been disconnected when you perform operations that require
the device to be powered off.
Examining the installation site
The device can only be used indoors. For the device to operate correctly and have a prolonged
service time, the installation site must meet the following requirements.
Temperature and humidity
Make sure the temperature and humidity in the equipment room meet the requirements described

Lastin
g high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
2
Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting screws and circuit failure.
High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the device.
Table 1 Temperature and humidity requirements for the equipment room
Temperature Relative humidity
WX1804H-PWR/WX1820H:0°C~40°C (32°F to 104°F)
