1: Indicates the distribution area where the device is assumed to be connected, from the public power distribution network
to the local machine device.
Category II is applied to the devices to which the power is supplied from a fixed equipment.
The surge resistance voltage of a rated 300 V device is 2500 V.
2: This is an index which indicates the occurrence rate of the conductive object in the environment where the device is
used.
Pollution rate II indicates that only non-conductive pollution may occur with a possibility of generating temporary
conductivity due to accidental condensation.
3: Do not use or store the PLC under pressure higher than the atmospheric pressure of altitude 0m.
Doing so can cause a malfunction.
When using the PLC under pressure, please contact your sales representative.
