*1 Installation category (overvoltage category) II:
Describes a number which defines a transient
overvoltage condition.
Implies the regulation for impulse withstand
voltage.
“II” applies to electrical equipment which
is supplied from the fixed installation like a
distribution board.
*2 Pollution degree 2:
Describes the degree to which a solid, liquid,
or gas which deteriorates dielectric strength or
surface resistivity is adhering.
“2” applies to normal indoor atmosphere.
Normally, only non-conductive pollution occurs.
