The Compact I/O system is suitable for use in an industrial
environment when installed in accordance with these instructions.
Specifically, this equipment is intended for use in clean, dry
environments (Pollution degree 2
Over Voltage Category II
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level, transient
voltages are controlled and do not exceed the impulse voltage capability of the product's insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC)
designations.
