Immunity
*1 The Overvoltage Category (Installation Category) is a value used to define the transient overvoltage condition and includes
the impulse withstand voltage regulation. II applies to electrical equipment that is powered by a fixed installation such as a
distribution board.
*2 Pollution Degree: Applies to the degree of adhesion of a solid, liquid, or gas which deteriorates withstand voltage or surface
resistivity. Pollution Degree 2 applies to normal indoor atmospheres (with only non-conductive pollution).
*3 Measurement category II (CAT II) applies to measurement of electrical equipment which is supplied from fixed installations
such as a wall outlet wired from a distribution board, or of the wires themselves.
*4 Use cables of length 2 m or less.
*5 Use cables of length 30 m or less.
