Preparing for installation
Safety recommendations
General safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before
installation. Note that the recommendations do not cover every possible hazardous condition.
•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
in Table 1.
•Lasting 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)
•WX1810H-PWR:0°C~45°C (32°F to 113°F) 5% to 95% (noncondensing)
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.
Table 2 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m3)
Dust particles
≤3 x 104
(No visible dust on desk in three days)
NOTE:
Dust particle diameter ≥5 µm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.
Table 3 Harmful gas limits in the equipment room
Gas Max. (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
Cooling
•Leave a minimum of 10 cm (3.94 in) of clearance around the chassis for heat dissipation.
•Make sure a good ventilation system is available at the installation site.
ESD prevention
To prevent electrostatic discharge (ESD), follow these guidelines:
•Make sure the device is reliably grounded.
•Take dust-proof measures for the equipment room.
•Maintain the humidity and temperature in the equipment room in the acceptable range.

3
•Always wear ESD gloves and ESD garment and remove conductive objects such as jewelry or
watch before working with the device.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the device and application
system, adversely affect the device in the following ways:
•A conduction pattern of capacitance coupling.
•Inductance coupling.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•Take effective measures to filter interference from the power grid.
•Keep the device far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning
strikes, route interface cables only indoors.
Lightning protection
To enhance lightning protection for the device, follow these guidelines:
•Make sure the device is reliably grounded.
•Make sure the AC power outlet is reliably grounded.
•Install a surge protected power strip at the power input end.
