The size class of the RD51.1-4N-018-D-NN-FW is B. A radio interference suppression filter is incorporated on the drive. This filter reduces the harmonics in the power that is fed back into the line supply. The protection category of the drive housing is IP20. This indicates that the housing provides limited solid protection but does not provide any liquid protection. Therefore the drive should not be used outdoors. Even when installed indoors, the drive should be mounted inside a control cabinet that can provide the desired level of environmental protection. Configuration and programing of the RD51.1-4N-018-D-NN-FW can be done through an optional control panel or a PC-based software. Reliable drive operation is dependent upon proper installation.
