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 Figure 3.19 on page 3-18 . It is necessary to provide a +
24 Vdc +/- 10 % external power supply to feed this board. This external power supply must have 300 mAdc
minimum capacity.
