Chapter 5 Commissioning the Drive
Trace the power cabling from termination point to termination point while
examining the cable and its routing for mechanical damage, sharp bend radiuses
and sources of induced noise and heat. Ensure that the power cabling is
sufficiently braced so as to contain the cabling in the event of a ground fault
situation.
Verify that all cables are terminated on each end and are sufficiently torqued (see
Torque Requirements for Threaded Fasteners on page 119 ).
Verify that the cable installed meets the recommended power rating outlined in
the electrical drawings and installation section of the manual. Ensure that the
cable terminations are stress-coned, if required.
Verify that the customer power cables have been Hi-Potted or meggered and read
a sufficient insulation value.
Control Wiring Identify all customer-required control wiring detailed on the electrical diagram,
and locate it within the terminal blocks in the drive. Examine it to verify that the
cable insulation has not been tightened into the terminal. Verify that all
connections have proper continuity.
Ensure factory jumpers installed and marked with notes “to remove if remote
equipment installed” have been removed.
Inspect the control cable routing to ensure that DC control wiring and AC
control wiring are separated from each other. Routing them together in the same
bundle, wire-way or conduit may induce unwanted noise in the drive control. In
the overhead cable tray provided at the front of the drive, ensure that the AC
control, DC control and fiber optic cables remain isolated from each other by the
available dividers.
Inspect for additional control not shown on the electrical diagram. Determine its
purpose, mark the changes on the electrical diagram, and send the prints to the
factory for future reference.
Perform a tug test on all control cables to ensure that they are securely fastened,
and check each plug and connector to ensure it is properly seated in its socket.
ATTENTION: Ensure that there is sufficient clearance between the installed
control wiring to the control cabinet and components carrying medium voltage.
Verify that closing the low voltage door does not swing the low voltage cables
into the medium voltage cabling section.
