8 Air conditioner If the temperature in the room exceeds 35°C, you are
recommended to install air conditioners (which can be
restarted after power-off). Do not let the air conditioner blow
directly toward the devices.
9 Moisture-proof
measures
If the relative humidity is greater than 70%, install the
dehumidifying device, such as the air conditioner with the
dehumidification function or special dehumidifier. Ensure that
the equipment room is protected from water seepage and dew.
10 Heating For an environment where the average daily temperature is
lower than 5°C for at least 90 days each year, heating devices
are required. For an environment where the average
temperature is lower than 5°C for 60 to 90 days each year,
heating devices are recommended.
11 Ventilation and
heat dissipation
To ensure smooth ventilation, the cabinet should be at least
100 cm (39.4 inches) away from the walls and you should
leave a clearance of at least 120 cm (47.28 inches) between
the cabinets. To keep a convective air transfer between the
cabinet and the equipment room, no enclosed space is allowed
in the cabinet. 1 U space should be left above and below each
device.
12 Dust-proof
measures
For the equipment room near dust sources (such as coal
mines, country roads, or farmland), use double-layer
aluminum alloy windows for proper sealing and an anti-theft
and fireproof door. Separate the devices from the door with a
partition board to avoid dust.
13 Ground resistance Less than 10 Ω. The distance between the top of the ground
terminal and the ground should be at least 0.7 m (27.58
inches). In the cold regions, the ground terminal should be
buried under the layer of frozen earth. Periodically monitor
ground resistance to ensure ground effectiveness.
