Wiring
Wiring Recommendations
Good wiring practice requires the separation of control circuit wiring from all
power (line) wiring. In addition, power wiring to the motor must have the
maximum possible separation from all other power wiring, whether from the
same drive controller or other drive controllers. Do not run power and
control wiring, or multiple power wiring, in the same conduit. This separation
reduces the possibility of coupling electrical transients from power circuits
into control circuits or from motor power wiring into other power circuits.
WARNING
IMPROPER WIRING PRACTICES
• Follow the wiring practices described in this document in addition to
those already required by the National Electrical Code and local
electrical codes.
• Do not apply input line voltage to the output terminals (U/T1, V/T2,
W/T3).
• Check the power connections before energizing the drive controller.
• If replacing another drive controller, verify that all wiring connections to
the ATV31C drive controller comply with all wiring instructions in this
manual.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.

Altivar® 31 Adjustable Speed Drives
Branch Circuit Protection
30072-451-94
6/2007
Follow the practices below when wiring ATV31C drive controllers:
Branch Circuit Protection
•
Verify that the voltage and frequency of the input supply line and the
voltage, frequency, and current of the motor match the rating on the
drive controller nameplate.
•
Use metallic conduit for all drive controller wiring. Do not run control and
power wiring in the same conduit.
•
Separate the metallic conduits carrying power wiring from those carrying
control wiring by at least 76 mm (3 in.).
•
Separate the non-metallic conduits or cable trays carrying power wiring
from the metallic conduit carrying control wiring by at least 305 mm
(12 in.).
•
Whenever power and control wiring cross, the metallic conduits and
non-metallic conduits or trays must cross at right angles.
•
Equip all inductive circuits near the drive controller (such as relays,
contactors, and solenoid valves) with noise suppressors.
Refer to NEC Article 430 for sizing of branch circuit conductors. Ensure that
all branch circuit components and equipment (such as transformers, feeder
cables, disconnect devices, and protective devices) are rated for the input
current of the ATV31C drive controller, or for the rated output current,
whichever value is larger. The input current of the controller depends on the
impedance of the power distribution system and the available short-circuit
current at the drive input terminals.
The tables in the Drive Reference section of the Altivar® 31C Installation
Manual provide input current information to optimally size branch circuit
conductors. Do not exceed the short-circuit current rating shown in the
tables. The short-circuit current rating is the available short-circuit current
capability on the line side of the fuses or circuit breakers.
A line reactor can be used to add impedance and reduce the available
short-circuit current capability to the level allowed by the drive controller.
NOTE: Ensure that the branch circuit feeder protection rating is not less
than the rated output current of the drive controller.
When more than two drive controllers are installed in parallel on a common
power line voltage, regardless of voltage rating, an individual line reactor per
drive controller is recommended. This provides filtering between controllers
and reduces harmonic distortion when the system is partially loaded.
WARNING
INADEQUATE OVERCURRENT PROTECTION
• Overcurrent protective devices must be properly coordinated.
• The National Electrical Code and the Canadian Electricity Code require
branch circuit protection. Use the fuses listed on the drive controller’s
nameplate to achieve published short-circuit current ratings.
• Do not connect the drive controller to a power feeder whose short-circuit
capacity exceeds the drive controller short-circuit current rating listed on
the drive controller nameplate.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.

Output Wiring
30072-451-94
6/2007
If starting the drive controller from line power, limit operations of the line
contactor to less than once per minute to avoid premature failure of the filter
capacitors and precharge resistor. Use the logic inputs to command the
drive controller.
Output Wiring
The drive controller is sensitive to the amount of capacitance (either phaseto-phase or phase-to-ground) present on the output power conductors.
Excessive capacitance can cause an overcurrent trip. Follow these
guidelines when selecting output cable:
•
Cable type: The cable selected must have a low capacitance
phase-to-phase and phase-to-ground. Do not use mineral-impregnated
cable because it has a very high capacitance. Immersion of cables in
water increases capacitance.
•
Cable length: The longer the cable, the greater the capacitance. Cable
lengths greater than 30.5 m (100 ft.) can affect the drive controller and
motor performance.
•
When the output cable is in close proximity to other output cables, the
drive controller may fault under some conditions because of high
frequency switching and increased capacitance.
•
Do not use lightning arrestors and/or power factor correction
capacitors on the output of the drive controller.
For proper drive controller short circuit protection, certain values of
inductance may be required in the output power wiring. Inductance can be
supplied by the power wiring or auxiliary inductors.
CAUTION
INSUFFICIENT OUTPUT INDUCTANCE
Provide at least 500 mm (20 in.) of cable at the drive controller output
(U/T1, V/T2,W/T3) to help protect the drive controller output when short
circuits occur.
Failure to follow this instruction can result in injury or equipment
damage.

Instruction Bulletin
Logic Input Switch
30072-451-94
6/2007
NOTE: All terminals are located at the bottom of the drive controller. Install
interference suppressors on all inductive circuits—such as relays,
contactors, solenoid valves, and fluorescent lighting—that are near the drive
controller or connected on the same circuit.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Prevent accidental grounding of logic inputs configured for Sink Logic.
Accidental grounding can result in unintended activation of drive
controller functions.
• Protect the signal conductors against damage that could result in
unintentional conductor grounding.
• Follow NFPA 79 and EN 60204 guidelines for proper control circuit
grounding practices.
Failure to follow these instructions will result in death or serious
injury.
