Installation (Overvoltage) Class This product is powered by a main power supply
conforming to Installation (overvoltage) Class II.
Warning:
Ensure that no overvoltage (such as voltage caused by lightning) reaches the
product. Otherwise, the operator may suffer electric shocks.
Installation (overvoltage) class definition
Class I refers to the signal level, which is applicable to the measuring terminal of the
instrument connected to the source circuit. Measures have been taken to limit the
instantaneous voltage to the corresponding low level.
Class II refers to the local distribution level, which is applicable to instruments connected
to the mains (AC) supply.
Pollution level
Level 2
Pollution level definition
⚫ Level 1: No pollution, or only dry non-conductive pollution. This pollution level has
no impact. For example: clean room or air-conditioned office environment.
⚫ Level 2: Generally, only dry non-conductive pollution. Temporary conduction due to
condensation may sometimes occur. For example: general indoor environment.
⚫ Level 3: Conductive pollution, or dry non-conductive pollution becoming conductive
due to condensation. For example, an outdoor environment with a canopy.
⚫ Level 4: Permanent conductive pollution through conductive dust, rain, or snow.
For example: outdoor places.
