Overview of installation work
NOTICE
All cables and wiring must, at a minimum, follow
the current NEC (National Electrical Code)
Handbook requirements or equivalent,
and must comply with all local codes.
Any ABB recommendations will not
replace these requirements.
Codes address cable selection from a safety and
fire protection point of view; however, cables have
a significant impact on the drive performance
and reliability. Therefore, additional consideration
is necessary for cable selection and installation
to ensure safe and reliable operation.
The electrical installation includes the following
wire and cable connections:
• Line supply and motor cables, ground cable and
bonding conductors. See section Line supply
and motor cables
• Auxiliary power and control cables. See section
Auxiliary power, control and fieldbus
communication cables
Cables and wires
Medium voltage power cables
Cable insulation
The cables to the main power input busses of the
drive can be exposed to common mode voltages
resulting from normal drive operation. For this
reason, shielded cables rated 5 kV (phase to
earth/phase to phase) or higher must be utilized.
All power cables must be terminated with
stress cones.

Three-core cables
A cable with three individually shielded conductors
is recommended to ensure compliance with EMC
(Electro Magnetic Compatibility) requirements,
and to provide a low impedance high frequency
path through which the common mode currents
can flow. Shields should be terminated and
grounded to a low impedance conductor at
both ends. The drive includes a ground bus
within the cable termination compartment
in order to facilitate this.
A non-shielded three-core cable with a continuous
corrugated aluminum armor may be used as an
alternative. Steel armored or interlocked
aluminum armored cable should not be used.
The maximum installed three-core cable length
should not exceed 300 meters [1000 feet].
See Appendix H - Power Cable
Specifications, located on the CD, for
detailed cable information.
