*1 Indicates to which power distribution section, from the public power distribution network to the in-plant
machine device, the device is assumed to be connected.
Category II applies to a device fed power from a fixed facility.
The withstand surge voltage level for a device with a rating up to 300V is 2500V.
*2 Exponential indicating the degree of conductive matter generated in the environment where device is
used.
In the degree of contamination level 2, only non-conductive contaminants are generated. However,
temporary conductivity could occur due to rare condensation.
*3 Do not use or store the programmable controller in the environment where the pressure is higher than the
atmospheric pressure at sea level. Otherwise, malfunction may result. To use the programmable controller
in high-pressure environment, contact your nearest Mitsubishi representative.
