z
Environments that may be damaged by lightning.
z
Environments in which forces or gravity may deform the body of the
product.
z
Environments containing harmful gases such as silicone.
z
Locating the cables of the product near the power lines of other
machines.
z
Conditions in which insufficient grounding for the power supply is
provided.
z
Conditions that cause dew condensation (this may occur on the surface
of the piping when the Facility Water temperature is low).
z
Places not allowing a space of 50mm or more at the air inlet of the
Surroundings of product and thus causing the sucking of exhausted heat
from the air inlet.
z
Places preventing the horizontal set-up of the product.
3.2.2 Installation in Clean Room
This product uses a fan and generates dust. When it is set up and operated
in a clean room, take appropriate preliminary measures for dust.
3.2.3 Pollution Degree
The pollution degree is a classification from 1 to 4 degrees depending on
the pollution present in the air. This product is suitable for environments with
a pollution degree of 1 or 2.
Table 3-1 Pollution degree classification
Degree 1
There is no pollution or only dry and nonconductive pollution occurs.
An example of an environment of this degree is a clean room or a place using an
air cleaner.
Degree 2
Normally, only nonconductive pollution occurs. The pollution may become
conductive temporarily because of dew condensation.
An example of an environment of this degree is a place where electric equipment
can operate normally, such as a working office or a control panel.
Degree 3
Conductive pollution or dry and nonconductive pollution which can become
conductive when dew condensation occurs. An example of an environment of this
degree is a factory.
Degree 4
Conductive pollution that holds its conductivity due to conductive dust, rain or
snow. An example of an environment of this degree is the outdoors.
z This product can be used in environments with pollution degree 1
or 2.
