All of the hardware required for assembling the equipment

across the shipping splits is furnished with the equipment. If

a transformer is included in the line-up of equipment, the

transformer flange should be aligned with the opening in the

side of the transition compartment and fastened together

using the 3/8-16 bolts, nuts and washers supplied with

switchgear. The fastener assembly should be tightened with

a torque of 25-30 ft-lbs.

COMPLETE THE ELECTRICAL

INTERCONNECTIONS - After completing the

mechanical connections between the several sections of

equipment, the electrical interconnections should be

completed. This includes the installation of splice

plates for the main bus bars, the neutral bus, and the

ground bus in addition to the Entellisys control and

communication circuitry.

WARNING: All switchgear equipment must be

adequately grounded for safety. Failure to ground

equipment properly may result in serious injury.

ADVERTISSEMENT: Tout l’équipement du dispositif de

commutation doit être mis à la terre adéquatement de

manière sécutaire. Des blessures sérieuses peuvent

survenir si l’on omet de mettre l’équipement à la terre

correctement.
