    Operation Overview • Reverse Voltage The Load conducts a reverse current when the polarity of UUT connection is not correct. The maximum safe reverse current is the same as the rated current of the load. If the reverse current of the UUT is over the rated current of load, the load may be damaged. If a reverse voltage condition is detected, you must turn off power to the UUT immediately, and make a correct connection.
