Ecowatt ® Drive K120 series Technical data
A.1.2.2 Derating due to altitude
When the altitude of the site where the VFD is installed is lower than 1000 m, the VFD
can run at the rated power. When the altitude exceeds 1000m, derate by 1% for every
increase of 100m. When the altitude exceeds 3000m, consult the local Kruger dealer or
local Kruger office for details.
A.1.2.3 Derating due to carrier frequency
The power of the VFD varies according to carrier frequencies. The rated power of the
VFD is defined based on the carrier frequency set in factory. If the carrier frequency
exceeds the factory setting, the power of the VFD is derated by 10% for each increased 1
kHz.
A.2 CE
A.2.1 CE marking
The CE marking on the name plate of the VFD indicates that the VFD is CE-compliant,
meeting the regulations of the European low-voltage directive (2014/35/EU) and EMC
directive (2014/30/EU).
A.2.2 EMC compliance declaration
European union (EU) stipulates that the electric and electrical devices sold in Europe
cannot generate electromagnetic disturbance that exceeds the limits stipulated in
related standards, and can work properly in environments with certain
electromagnetic interference. The EMC product standard (EN 61800-3) describes the
EMC standards and specific test methods for adjustable speed electrical power drive
systems. Kruger products have strictly followed these EMC regulations.
A.3 EMC regulations
The EMC product standard (EN 61800-3) describes the EMC requirements on VFDs.
Application environment categories
Category I: Civilian environments, including application scenarios where VFDs are
directly connected to the civil power supply low-voltage grids without intermediate
transformers
Category II: All environments except those in Category I.
VFD categories
C1: Rated voltage lower than 1000 V, applied to environments of Category I.
C2: Rated voltage lower than 1000 V, non-plug, socket, or mobile devices; power drive
systems that must be installed and operated by specialized personnel when applied to
environments of Category I
