Drive of category C1: drive of rated voltage less than 1000 V and intended for use in the
first environment.
Drive of category C2: drive of rated voltage less than 1000 V and intended to be installed
and started up only by a professional when used in the first environment. Note: A professional
is a person or organization having necessary skills in installing and/or starting up 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 C1
The drive complies with the conducted emission limits of the standard with the following
provisions:
1.
The optional EMC filter is selected according to section External EMC filters (page 111),
and the filter is installed as specified in the EMC filter manual.
2. The motor and control cables are selected as specified in this manual. The EMC
recommendations are obeyed.
3. The maximum motor cable length does not exceed the specified maximum value. See
EMC compatibility and motor cable length (page 113).
4. The drive is installed according to the instructions (IEC) given in this manual.
This product can cause radio-frequency inference. In a residential or domestic environment,
supplementary mitigation measures may be required in addition to the requirements listed
above for the CE compliance.
■ Category C2
This is applicable to drive with an internal EMC C2 filter. The filter is included to all drive
types as standard. However, for the UL(NEC) drive types it is not connected at the factory.
The user must re-connect it for the category C2 compliance.
The drive complies with the standard with the following provisions:
1. The motor and control cables are selected as specified in this manual. The EMC
recommendations are obeyed.
2.
The maximum motor cable length does not exceed the specified maximum. See EMC
compatibility and motor cable length (page 113).
3. The drive is installed according to the instructions (IEC) given in this manual.
This product can cause radio-frequency inference. In a residential or domestic environment,
supplementary mitigation measures may be required in addition to the requirements listed
above for the CE compliance.
WARNING!
Do not install a drive with the internal EMC filter connected to an earthing system
that it is not suitable for (for example, an IT system). The supply network becomes
connected to ground potential through the internal EMC filter capacitors, which
can cause danger or damage to the drive.
