Sequentially apply the rated voltage to input CC1 and CC2 (A8-A10 and A9-A10).
Check that when voltage is applied to one contact input, only this input gets active, and the other one remains inactive. Use
the INFORMATION menu on the faceplate or a PC and the ACTUAL VALUES menu in the ENERVISTA MII SETUP
program (Actual> Actual Values) to easily check which input gets active for each test.
Repeat this test at minimum and maximum permissible voltages.
