Precautions while using Power Supply
Output and Ground Connections
The Power Supply output is a floating output i.e., the primary side and secondary side are separated , so the output line i.e., +V or V can be connected externally directly to a ground. Through the ground, however, the insulation between the primary side and secondary side will be lost. Confirm that no loops are created in which the Power Supply output is short circuited through the internal circuits of the load.
