●
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 affected).
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.
