           6  Control  the  terminal  voltage  to  approx.  250  V  by  decreasing  the  field  current  by  manually  adjusting  field
              rheostat.
           Safety precautions:

           1  Ensure proper foundation and perfect coupling of MG set, else it may cause severe injury.
           2  Ensure proper direction of rotation of DC generator to avoid demagnetizing of field poles and fails to build up
              voltage.

           3  Do not make loose and wrong connections; check the connections before switching ON.
           4  Ensure proper earthing to the MG set.
