APPENDIX A2 MANDATORY INSTALLATION INSTRUCTION ACCORDING TO THE EMC DIRECTIVE
A2.1
EN61800-3 EMC product standard for adjustable speed electrical power drive systems
EN 61800-3:2004 Adjustable speed electrical drive systems. Part 3: EMC product standard including specific test methods. The transition period for
the existing EN 61800-3:1996 expires on 1st October 2007.
The EN 61800-3 includes the electrical power drive system from the mains connection to the shaft of the motor, defines different categories C1 to C4,
different environments (residential areas/industrial areas), external ports and internal interfaces.
It defines assessment criteria for the operational performance in case of interference at the external ports and the internal interfaces according to the
environment at the installation site.
A2.1.1 INSTALLATION
ENVIRONMENT
(Definitions)
First environment (residential and commercial areas):
Environment that includes domestic premises. It also includes establishments directly connected without intermediate transformers to a low-voltage
power supply network which supplies buildings used for domestic purposes.
Second environment (industrial area):
Environment that includes all establishments other than those directly connected to a low-voltage power supply network, which supplies buildings
used for domestic purposes.
NOTE
“For PDS’s in the second environment, the user shall ensure that excessive disturbances are not induced into low-voltage network, even if
propagation is through a medium voltage network.”
Private network
The private network is characterised by being supplied by a dedicated medium voltage network and not supplying residential areas. Typically, the
private main supplies commercial premises, offices in a residential building, shopping centres, etc. The operator can decide whether he realises the
network according to the first or second environment as defined by the standard.
A private low-voltage network can be regarded as a plant in compliance with the EMC law. The EMC is assessed according to the physical limits of
the plant, emission and immunity to radiated RF-fields are assessed according to the space limits and conducted phenomena are assessed according
to the input to the supplying network
A2.1.2
EN 61 800-3 Categories
Classification of categories according to environments
Category C1: Drive systems for rated voltages less than 1000 V for unlimited use in the first environment.
Category C2: Stationary drive systems for rated voltages less than 1000 V for use in the second environment. It is possible the use in the first
environment which fulfil all the following criteria:
Rated voltage < 1000 V
No plug-in device
No movable device
Installation and commissioning only by a professional (a person/organisation having necessary skills in installing and/or
commissioning power drive systems, including their EMC aspects)
Warning required.
Warning in the instructions for use:
“This is a product of category C2 according to IEC 61800-3. In a domestic environment this product may cause radio interference in
which case supplementary mitigation measures may be required.”
Category C3: Drive systems with rated voltage < 1000 V, intended for use in the second environment and not intended for use in the first
environment.
Warning in the instructions for use:
“This type of PDS is not intended to be used on a low-voltage public network which supplies domestic premises. Radio frequency
interference is expected if used on such a network”.
Category C4: for use in the second environment, which fulfil at least one of the following criteria:
Rated voltage
≥
1000 V
Rated current
≥
400 A
Connected to IT networks
Required dynamic performances will be limited as a result of filtering
An EMC plan is to be established!
