Capacitor Voltage Monitoring Board IS200CVMBG1AAA was designed with the ability to monitor voltages across DC link capacitors on drives in the Innovation Series in mind. This model has the capability to provide a subsidiary indication of voltage presence for anyone who will open the bridge cabinet doors. The CVMB model does not have any fuses, adjustable hardware, connectors, or test points. When the board is being mounted it will mount directly to the DC power capacitor terminals. It is vital to the operation of the IS200CVMBG1AAA board to note that it does not require any input power, but the model does have the ability to dissipate approximately three to five watts of power.
The mounting of the IS200CVMBG1AAA board will be done through the plated mounting holes which are identified with the numbers E1 through E4. There are specific connections required when connecting the model which are as follows, E4 is the DC link negative connection, the E3 connection is NEU2 which is 2000 VDC which is relative to the negative indicated by DS2, with the E2 connection being the NEU2 which is also 2000 VDC relative to the negative indicated by DS1, with the E1 mounting point labeled as the POS nomenclature at 4000 VDC relative to the negative indicated by DS3.
The easiest way to identify this model is by the alphanumeric catalog number which is the IS200CVMBG1AAA number. In the GEI-100415 Manual, there is a figure which indicates the board part number conventions. For example, it details that CVMB is the functional acronym with the G being the group variation of the model.
