Chapter 2 Preparation and Inspection
Interconnection Review The interconnection checklist summarizes the required items to review to
validate the reconnection of power, ground, and control cables between cabinets
within the drive system, that were disconnected for shipment. Power and control
cables that pass from one cabinet to another are bundled in the appropriate
cabinet. These cables are connected for system test at the factory but
disconnected and coiled up for shipment. If this interconnection work was done
by the contractor, use this checklist to review and ensure the work was done
correctly. If the interconnection work was not done by the contractor, the scope
of work required to be performed is described in
6000-IN006_-EN-P .
.
IMPORTANT Check torque on all power and ground cable connections per specifications
listed in
Torque Requirements on page 81 .
