Installation (Overvoltage) Category
This product is powered by mains conforming to installation (overvoltage) category II.
Warning:
Ensure that no overvoltage (e.g. from lightning) reaches the product. Otherwise,
the operator may be in danger of receiving electric shock.
Installation (Overvoltage) Category Definitions
Installation (overvoltage) category I refers to signal level which is applicable to
equipment measurement terminals connected to the source circuit. Among these
terminals, precautions are done to limit the transient voltage to a low level.
Installation (overvoltage) category II refers to the local power distribution level
which is applicable to equipment connected to the AC line (AC power).
Pollution Degree
Pollution Degree 2
Pollution Degree Definition
⚫ Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The
pollution has no effect. For example, a clean room or air-conditioned office
environment.
⚫ Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary
conductivity caused by condensation is to be expected. For example, indoor
environment.
⚫ Pollution Degree 3: Conductive pollution or dry nonconductive pollution that
becomes conductive due to condensation occurs. To be found in industrial
environment or construction sites (harsh environments). For example, sheltered
outdoor environment.
⚫ Pollution Degree 4: The pollution generates persistent conductivity caused by
