(2) Dustproof and waterproof features
The control panel also has the dustproof and waterproof functions. Insufficient
dustproof and waterproof features lower the insulation withstand voltage, resulting in
insulation destruction.
The insulation in our programmable controller is designed to cope with the pollution
level 2, so use in an environment with pollustion level 2 or below.
Pollution level 1 : An environment where the air is dry and conductive dust
does not exist.
Pollution level 2 : An environment where conductive dust
does not usually exist, but occasional temporary
conductivity occurs due to the accumulated dust.
Generally, this is the level for inside the control box
equivalent to IP54 in a control room or on the floor of a
typical factory.
Pollution level 3 : An environment where conductive dust exits and
conductivity may be generated due to the accumulated
dust.
An environment for a typical factory floor.
Pollution level 4 : Continuous conductivity may occur due to rain, snow, etc.
An outdoor environment.
As shown above, the programmable controller can realize the pollution level 2 when
stored in a control panel equivalent to IP54.
