IMPORTANT
Each medium voltage door has its own isolation switch handle and
interlocking safeguards. Upper and lower power cells are separated
by an isolation barrier.
IMPORTANT
Ensure that the swing-out low voltage panel is in its original
position before attempting to close the MV door. When closing the
medium voltage door, ensure all door locking bolts on the right side
of the MV door are in place and tightened until the door is flush with
the flange.
Do not overtighten the bolts
. If the door is not securely
fastened, it will not be possible to move the isolation switch handle
to the ON position.
ATTENTION:
Complete the Power Lock-out procedure (see
) before beginning any service procedures to
the unit. Failure to do so may result in severe burns, injury or death.
