Notes:
[1] “Restricted Installation” means that the installation and commissioning must be
carried out by specialist personnel.
[2] C4 Category applies only for complex systems or when ratings are equal or above
to 1000 V or 400 A wich are unable to comply with the limits of C3 Category. In these
cases, C4 Category can be achieved by adjusting the equipment in situ and applying
the EMC recommendations.
SD300 compliance
SD300 variable speed drives with Extended EMC have been designed for
the industrial use (Second Environment). In the case of the Standard EMC
equipment, an external filter must be installed to meet C3. The correct
installation following the recommendations within this manual, permit to
achieve compliance with C3 category defined in IEC/EN 61800-3.
Optionally, the SD300 drive with non-floating earth can be installed in
residential areas (First Environment) by employing optional RFI filters that
permit to achieve the C2 category.
The SD300 is not a retail unit. It is neither a plug in device nor a movable
device and it is intended to be installed and commissioned by qualified
personnel. However, C1 category will not be required.
The SD300 with floating earth configuration can be installed in industrial
(Second Environment) IT grids. Equipment with Extended EMC comply
with C3 (Second Environment). In the case of the Standard EMC
equipment, an external filter must be installed to meet C3.
