A variable-speed drive system (or Power Drive System PDS) consists of the converter as well
as the associated electric motors and encoders including the connecting cables.
The driven machine is not part of the drive system.
Note
PDS as component of machines or systems
When you install PDS into machines or systems, additional measures may be required so that the
product standards of these machines or systems is complied with. The machine or system
builder is responsible for taking these measures.
Overview of environments and categories
Environments
IEC/EN 61800-3 makes a distinction between the "rst environment" and "second
environment" - and denes dierent requirements for these environments.
• First environment
Residential buildings or locations at which the PDS is directly connected to a public low-
voltage supply without intermediate transformer.
• Second environment
An environment that includes all other establishments which are not connected directly to a
public low-voltage line supply.
Categories
• Category C1
Power Drive System (PDS) of rated voltage less than 1000 V intended for use in the rst
(residential) environment.
• Category C2
Power Drive System (PDS) of rated voltage less than 1000 V, which is neither a plug-in device
nor a movable device, and when used in the rst environment, is only intended to be installed
and commissioned by a professional.
• Category C3
Power Drive System (PDS) of rated voltage less than 1000 V intended for use in the second
(industrial) environment and not intended for use within the rst (residential) environment.
Second environment - category C2
Conducted and radiated interference emissions
The converters meet the limit values of IEC 61800-3 Category C2 with regard to conducted
and radiated interference emissions under the following conditions:
• EMC compliant installation and conguration by qualied technician
• Operation on TN or TT line supply with grounded neutral point
• Permissible motor cable length
Maximum permissible cable length (Page65)
