Definition of Standard IEC/EM 61800-3: “Adjustable Speed Electrical Power

Drives Systems”

 Environments:

First Environment: Environments that include domestic installations, as well as

establishments directly connected without intermediate transformer to a low-voltage

power supply network which supplies buildings used for domestic purposes.

Second Environment: includes all establishments other than those directly connected to

a low-voltage power supply network that supplies buildings used for domestic purposes.

 Categories:

Category C1: drives with a rated voltage below 1000 V and intended for use in the

First Environment.

Category C2: drives with a rated voltage below 1000 V intended for use in the First

Environment, not provided with a plug connector or movable installations. They must

be installed and commissioned by a professional.

NOTE!

A professional is a person or organization familiar with the installation

and/or commissioning of drives, including their EMC aspects.

Category C3: drives with a rated voltage below 1000 V and intended for use in the

Second Environment only (not designed for use in the First Environment).
