connecting cable insulation must accommodate the voltage peaks
described under
Motor Insulation Requirements
on page vi of the
Safety Instructions.
For drives that are rated up to 500 V, cables that have a 600 VAC
insulation rating are suitable for both input power and motor wiring.
For drives that are rated over 500 V up to 600 V, cables that have a 600
VAC insulation rating are suitable for input power wiring. The motor
wiring requires a higher voltage rating to accommodate the voltage
peaks described under
Motor Insulation Requirements
on page vi of
the Safety Instructions. As a general rule, the motor cable insulation
should be rated for a minimum of 1000 V.
For drives that are rated over 600 V up to 690 V, cables that have a
1000 VAC insulation rating are suitable for both input power and motor
wiring.
Wiring Practices
NOTE! When installing the ACx 600 wiring, it is important to carefully
follow the wiring practice recommendations presented in the following
paragraphs. Following these recommendations will ensure reliable long
term operation of the ACx 600 drive. If these recommendations are not
followed, the drive may experience various problems such as:
•
Improper drive performance
•
Nuisance shutdown trips
•
Damage to drive electronic circuits
Incorrect installation practices can also cause malfunctions or damage
to other equipment through electromagnetic interference (EMI) and
noise injected into the grounding system.
The drive warranty does not cover problems caused by improper
installation.
When installing AC drive power wiring, wiring methods that provide
shielding for the power cables reduce the possibility of electromagnetic
interference (EMI). It is also important to ground the motor frame using
a ground conductor connected to the grounding terminal in the drive.
EMI reduction measures are most important for the motor wiring but
are also applicable to the input power wiring.
Any wiring method that is in conformance with applicable safety
regulations is acceptable for input power wiring. Metallic conduit or
armored cable must be used for motor wiring. Detailed conduit and
armored cable wiring practice guidelines are provided below.
