Forced air cooling
The VFD models of 045P and lower contain built-in
braking units. The braking units are optional parts
for the 055P–055/075P VFD models, and the braking
units can be built in or externally connected.
The transmission of the VFD meets the IEC/EN
61800-3 C3 requirements.
When optional filters are connected externally, the
transmission of the VFD can meet the IEC/EN 61800-3
C2 requirements.
Note: Comply with the EMC requirements and the
technical requirements for the motors and motor
cables in the appendix in the manual.
