The high voltage that is produced by an operating generator set can cause severe injury or death. Before performing any maintenance or repairs, ensure that the generator will not start. Place the engine control switch in the "OFF" position. Attach "DO NOT OPERATE" tags to all starting controls. Disconnect the batteries or disable the starting system. Lock out all switchgear and automatic transfer switches that are associated with the generator. |
Personal injury or death can result from electrocution. The megohmmeter is applying a high voltage to the circuit. To avoid electrocution, do not touch the instrument leads without first discharging them. When finished testing also discharge the generator windings. |
Refer to the correct OEM manual for information concerning testing the insulation.
