This equipment contains several circuits that are energized with high voltage. Only test
equipment designed for troubleshooting should be used. This is particularly true for
oscilloscopes. Always check with an AC and DC voltmeter to ensure safety before making
contact or using tools. Even when the power is turned Off, dangerously high potential electric
charges may exist at the capacitor banks and at the batteries.
All power and control wiring must be installed by a properly trained and qualified electrician.
All power and control wiring must comply with the NEC and applicable local codes.
When performing maintenance with any part of the equipment under power, service
personnel and test equipment must be standing on rubber mats. The service personnel must
wear insulating shoes for isolation from direct contact with the floor (earth ground).
One person should never work alone, even if all power is disconnected from the equipment. A
second person should be standing by to assist and to summon help in case of an accident.
