This procedure requires contact with medium
voltage components. To avoid shock hazards, lock
out incoming power before working on the
equipment. (See Power Lockout Procedure, page
5-3). Verify with a hot stick or appropriate
voltage measuring device that all circuits are
voltage free. Failure to do so may result in severe
burns, injury or death.
