● Class B (uncontrollable environment): indoor environments where the
ambient temperature and humidity are not controlled or general outdoor
environments with simple shielding measures where the humidity reaches
100% occasionally
● Class C (adverse environment): sea environments or outdoor land
environments (with simple shielding measures) near pollution sources.
● Class D (marine environment): environments within 500 m away from the
coast
NO TE
If an outdoor unit needs to be used at a site 3.7–10 km away from the coast in a class B
environment, it is recommended that the unit be installed in a shielded area, such as a
podium building, ground, or building rear, to prevent mechanical parts from being corroded
by sea wind (the functionality and reliability of the system must not be
aected).
Alternatively, use an outdoor unit that supports class C environments to avoid corrosion. If
the site is more than 10 km away from the coast, the unit can be properly installed.
Pollution sources in Class C environments refer to the following areas:
● Areas within 3.7 km away from saline water areas such as the ocean and saline lakes
● Areas within 3 km away from serious pollution sources, such as metallurgic plants, coal
mines, and heat and power plants
● Areas within 2 km away from medium pollution sources, such as chemical factories,
rubber plants, and electroplating factories
● Areas within 1 km away from light pollution sources, such as food factories, tanneries,
and heating boilers
The NetCol500-A060MS outdoor unit must not be installed in class D environments, and
other outdoor units must not be installed in class C or class D environments.
