ATTENTION:
This procedure requires contact with medium voltage
components. To avoid shock hazards, lock out incoming power
before working on the equipment (See
). 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 (See
Starter Identification on page 9
for details regarding the nameplate).
IMPORTANT
Attach the bus links to the cabinet on the left side first - as
