                        1. The secondary winding must never be left open while the primary circuit is energized. An open secondary circuit may generate a hazardous overvoltage of several thousand volts, creating a serious risk to equipment and personnel. During maintenance, the secondary winding must be securely short-circuited and grounded.<\/li>\n\n\n\n
