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.

1) The power and ground bus splice kit can be found in a package

mounted to the front of the shipping skid.
