Altitude (m)
When the altitude exceeds 2000 m, configure an isolation transformer at the VFD input end.
When the altitude is higher than 3000 m but lower than 5000 m, consult INVT for technical
issues. It is not recommended that the VFD be used at the altitude higher than 5000 m.
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 VFD nameplate indicates that the VFD is CE-compliant, meeting the
regulations of the European low-voltage directive (2006/95/EC) and EMC directive
(2004/108/EC).
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 61800-3:2004) describes the EMC standards and specific test methods
for adjustable speed electrical power drive systems. Products must strictly follow these EMC
regulations.
A.3 EMC regulations
The EMC product standard (EN 61800-3:2004) 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
