
Check Supply Voltage does not exceed drive Voltage rating.

Check the number of supply phases is compatible with the drive.

If the power supply has a low supply impedance /high short circuit current
a Line reactor/Isolation transformer maybe required.

For generator Bourne power supplies please contact your IDL Authorised
Distributor for further guidance.

Ensure there is at least 30 seconds between each power-on.

Install suitably rated fuses/Circuit breakers .

If an earth leakage detection device is used (e.g.ELCB/RCD), a type B trip
characteristic which is suitable for protecting equipment with a DC
component should be used, 1 device for multiple drives should be avoided.
Install Line reactor as close to the drive as possible and under the following
conditions:

If phase-phase imbalance is >3% (3Ø drives).

To reduce Inrush current.

If power supply has a low supply impedance/high short circuit current.

If power supply is prone to dips or brown-outs.

If power supply is via a bus-bar and sliding contacts system.

Reduction in mains Harmonic emission.

Install External EMC filter if the motor cable length exceeds the
Electromagnetic interference reduction capability of the internal filter

Do Not Use EMC filters on IT (Ungrounded) or a corner grounded TN power
supply systems.
Default Configuration shown.
Install Output Choke under the following conditions:

If cable between the drive and motor exceeds 100m (screened cable), or
150m (un-screened cable).

If motor is not "inverter rated".

Whenever possible use a motor that is designed for operation from an
inverter.

Ensure the voltage rating of the drive and motor match, special care should
be taken with dual voltage motors and that the correct configuration has
been set.
