Wiring Instructions
General Instructions
Cable Characteristics
If you are using cables longer than 150 m (164 ft) between the drive and the motor, add output filters (for
more details refer to the catalog).
Use a shielded cable to meet the requirements of Category C2 or C3 according to the standard IEC 61800-
3, except when using a sinus filter. In this case, the use a non-shielded motor cable is possible.
To limit the currents in common mode, use common mode output filters (ferrite) in order to reduce the
circulating currents in the motor windings.
Standard linear capacity cables can be used with Altivar Process. Use of cables with lower linear capacity
could increase cable length performances.
The overvoltage limitation function [Motor surge limit.] SUL enables you to increase the cable length
while decreasing the torque performances (refer to Programming manual EAV64318).
Power and Circuit Protection
Where local and national codes require upstream protection with a residual current device, use a type A
device for three-phase drives used on single-phase mains and a type B device for three-phase drives as
defined in the IEC standard 60755.
Choose a suitable model integrating:
z High frequency current filtering,
z A time delay that helps to prevent a triggering of the upstream device caused by the load from stray
capacitance on power-on. The time delay is not available for 30 mA devices; in this case, choose
devices with immunity against nuisance triggering.
If the installation includes several drives, provide one "residual current device" per drive.
Control
z Keep the control circuits away from the power cables. For digital and analog inputs/outputs, use
shielded twisted cables with a pitch of 25...50 mm (1 in. and 2 in.), connecting the shielding to Ground
at each end.
z It is recommended to use cable ends, available on www.schneider-electric.com.
Equipment Grounding
DANGER
HAZARD OF FIRE OR ELECTRIC SHOCK
z Wire cross sections and tightening torques must comply with the specifications provided in this
document
z Do not use multi-conductor cables without cable lugs for any connection with a voltage higher than 25
Vac.
Failure to follow these instructions will result in death or serious injury.
DANGER
ELECTRIC SHOCK CAUSED BY INSUFFICIENT GROUNDING
Insufficient grounding causes the hazard of electric shocks
z Ground the drive system before applying voltage.
z Do not use conduits as protective ground conductors; use a protective ground conductor inside the
conduit.
z The cross section of the protective ground conductor must comply with the applicable standards.
z Do not consider cable shields to be protective ground conductors.
Failure to follow these instructions will result in death or serious injury.
