1 : 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 300 V is 2500 V. 
2 : This index indicates the degree to which conductive material is generated in terms of the environment 
where the equipment is used. 
Pollution level 2 is when only non-conductive pollution occurs but temporary conductivity may be produced 
due to condensation. 
3 : Do not use or store the programmable controller under pressure higher than the atmospheric pressure of 
altitude 0m. 
Doing so can cause a malfunction. 
When using the programmable controller under pressure, please contact your sales representative.
