NOTE!
This guide provides information for the installation of KVDC kit on the CFW-11
inverter without the suffix W (CFW-11) or W1 (CFW70X) in their description.
The KVDC-CFW11-2 is an optional component of the inverter, therefore, it cannot be sold to
end users or integrators separately.
It must always be installed by the WEG branch or WEG distributor, otherwise, the end user will
lose the warranty for opening the inner parts of the inverter.
