Definitions
EMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronic equipment to
operate without problems within an electromagnetic environment. Likewise, the equipment must not
disturb or interfere with any other product or system within its locality.
First environment includes establishments connected to a low-voltage network which supplies buildings
used for domestic purposes.
Second environment includes establishments connected to a network not supplying domestic premises.
Drive of category C2: drive of rated voltage less than 1000 V and intended to be installed and
commissioned only by a professional when used in the first environment. Note: A professional is a
person or organisation having necessary skills in installing and/or commissioning power drive systems,
including their EMC aspects.
Drive of category C3: drive of rated voltage less than 1000 V and intended for use in the second
environment and not intended for use in the first environment.
Drive of category C4: drive of rated voltage equal to or above 1000 V, or rated current equal to or above
400 A, or intended for use in complex systems in the second environment.
Category C2
The drive complies with the standard with the following provisions:
1. The drive is equipped with EMC filter +E202.
2. The motor and control cables are selected as specified in the Hardware Manual.
3. The drive is installed according to the instructions given in the Hardware Manual.
4. Maximum motor cable length is 100 metres (328 ft).
WARNING! The drive may cause radio interference if used in a residential or domestic environment.
The user is required to take measures to prevent interference, in addition to the requirements for CE
compliance listed above, if necessary.
Note: It is not allowed to install a drive equipped with EMC filter +E202 on IT (ungrounded) systems.
The supply network becomes connected to ground potential through the EMC filter capacitors which
may cause danger or damage the unit. See also section IT (ungrounded) systems on page 82.
Category C3
The drive complies with the standard with the following provisions:
1. The drive of frame size R6 is equipped with optional EMC filter +E200. (Frame sizes R7i and R8i
have EMC filter +E210 as standard equipment, and thus, they meet the Category 3 requirements as
default.) See also section IT (ungrounded) systems on page 82.
1. The motor and control cables are selected as specified in the Hardware Manual.
2. The drive is installed according to the instructions given in the Hardware Manual.
3. Maximum motor cable length is 100 metres (328 ft).
WARNING! A drive of category C3 is not intended to be used on a low-voltage public network which
supplies domestic premises. Radio frequency interference is expected if the drive is used on such a
network.
Note: It is not allowed to install a drive equipped with EMC filter +E200 on IT (ungrounded) systems.
The supply network becomes connected to ground potential through the EMC filter capacitors which
may cause danger or damage the unit. See also section IT (ungrounded) systems on page 82.
