PLEASENOTETHEFOLLOWING:
• Installation (Overvoltage) Category II
refers to local distribution level,
applicable to equipment connected to the
mains supply (AC power source).
• Installation (Overvoltage) Category I
refers to signal level, applicable to
equipment measuring terminals
connected to source circuits where
measures are taken to limit transient
voltages to an appropriately lower level.
• Pollution Degree 2 refers to an operating
environment where normally only dry
non-conductive pollution occurs.
Occasionally, a temporary conductivity
caused by condensation must be
expected.
• Protection Class 1 refers to grounded
equipment, where protection against
electric shock is handled by Basic
Insulation and by means of a connection
to the protective ground conductor in the
building wiring.
