Safety Compliance
Pollution Degree Description
A measure of the contaminants that could occur in the environment
around and within a product. Typically the internal environment inside
a product is considered to be the same as the external. Products should
be used only in the environment for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive
pollution occurs. Products in this category are generally
encapsulated, hermetically sealed, or located in clean rooms.
Pollution Degree 2. Normally only dry, nonconductive pollution
occurs. Occasionally a temporary conductivity that is caused
by condensation must be expected. This location is a typical
office/home environment. Temporary condensation occurs only
when the product is out of service.
Pollution Degree 3. Conductive pollution, or dry, nonconductive
pollution that becomes conductive due to condensation. These
are sheltered locations where neither temperature nor humidity
is controlled. The area is protected from direct sunshine, rain, or
direct wind.
vi 1103 Power Supply Instruction Manual

Compliance Information
Pollution Degree 4. Pollution that generates persistent conductivity
through conductive dust, rain, or snow. Typical outdoor locations.
Pollution Degree
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor
use only.
Installation (Overvoltage) Category Descriptions
Terminals on this product may have different installation (overvoltage)
category designations. The installation categories are:
Measurement Category IV. For measurements performed at the
source of low-voltage installation.
Measurement Category III. For measurements performed in the
building installation.
Measurement Category II. For measurements performed on circuits
directly connected to the low-voltage installation.
Measurement Category I. For measurements performed on circuits
not directly connected to MAINS.
