This indicates the section of the power supply to which the equipment is
assumed to be connected between the public electrical power distribution
network and the machinery within premises.
Category II applies to equipment for which electrical power is supplied from
fixed facilities. The surge voltage withstand level for up to the rated voltage of
300V is 2500V.
This index indicates the degree to which conductive material is generated in
terms of the environment in which the equipment is used.
Pollution level 2 is when only non-conductive pollution occurs. A temporary
conductivity caused by condensing must be expected occasionally.
Do not use or store the programmable controller under pressure higher than
the atmospheric pressure of altitude 0m. Doing so may cause malfunction.
When using the programmable controller under pressure, please consult
your local Mitsubishi Electric representative.
