Jumper provided in the standard common position and should be moved or removed as required.
If ganged units are used in a system that ordinarily has a common neutral or ground between source and load, the neutral or ground must be connected to the com-
mon terminals of the variable transformer assembly. If the system has no neutral, the load must be balanced or the transformers will be damaged.
