ATTENTION: This procedure requires contact with medium voltage
components. To avoid shock hazards, lock out incoming power before working
on the equipment (refer to
Power Lock-out Procedure on page 41 of Chapter 5 ).
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.
IMPORTANT Verify that the structure series numbers on the splice kit package
match the structure series number found on the cabinet nameplate
(refer to
Starter Identification on page 1 of Chapter 1 for details
regarding the nameplate).
IMPORTANT Attach the bus links to the cabinet on the left side first - as viewed from
the front of the unit.
IMPORTANT Always place the bus clamps on the rear side of each main horizontal
bus or splice bar, as viewed from the front of the unit (see
Figure 34 or
Figure 35 ).
