Information on Splice Kits
If the drive line-up was shipped in sections, verify that the bus splice kits provided
in this circumstance are properly installed and torqued at shipping split locations.
Power Cabling
Ensure that all customer power and control wiring required for drive line-up
installation are identified on the electrical drawings by a dashed line (see your
electrical drawing’s General Notes for additional information).
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 123 ).
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.
ATTENTION: Power cabling should be installed in accordance with local codes
and guidelines. The information in this section is to be used as reference only
and is not intended to replace practices outlined in the electrical code.
