Installation and Connection
The UR11 rectifier series was developed to be used in application with the CFW-11M (Modular Drive) inverter
series, which can be used in IT networks without modifications. In these cases consider the following:
The phase to ground or isolation fault indication must be processed by the user to indicate the failure
occurrence and/or block the inverter operation.
In order to use the UR11 for feeding other inverters, refer to the inverter respective manual.

The CIR11 (Rectifier Interface Board) is presented at
24 Vdc +/- 10 % external power supply to feed this board. This external power supply must have 300 mAdc
minimum capacity.
