Quick Start Guide
Always read the full instruction manual before using iDrive.
This quick start guide is to assist in installing and running the iDrive to verify that the iDrive
and motor are working properly. Starting, stopping and speed control will be from the
keypad. If your application requires external control or special system programming, consult
the iDrive EDX instruction manual supplied with your inverter.
Step 1 - Before applying power to your iDrive
Please refer to Chapter One (Preface) and Chapter Two (Safety Precautions) of the iDrive
EDX instruction manual. Verify drive is installed in accordance with the procedures as
described in Chapter Three (Environment and installation). If something is suspected of being
abnormal, do not apply power to the drive until qualified personnel have corrected the
situation. (Failure to do so could result in death or serious injury.)
• Check inverter and motor nameplates to determine that they have the same power and
voltage ratings. Ensure that full load motor current does not exceed that of the inverter.
• With power OFF, remove the terminal covers to expose the motor and power terminals.
a. Verify that AC power is wired to L1(L), L2, and L3(N) .
b. Verify that motor leads are connected to T1, T2, and T3 .
c. If a brake module is necessary, please connect terminal voltage of the braking unit to P
and N of the inverter. Never connect a resistor directly to iDrive terminals P and N.

E. Fuse types
Drive input fuses are necessary to disconnect the drive from the power supply in the event of component failure in
the drive’s power input circuit. The iDrive’s electronic protection circuitry is designed to clear output short circuits
and ground faults without blowing the input fuses. The table below shows the iDrive EDX input fuse ratings.
To protect the iDrive most effectively, use fuses with quick-blow characteristics (semi-conductor fuses).
It is the responsibility of the user/installer to ensure that the correct fuse protection (or other) is applied.

Notes
1. To comply with BS7671 requirements the iDrive must be earthed by a conductor(s) of
minimum 4 mm2c.s.a. with additional mechanical protection. Therefore the iDrive must be
installed in a steel enclosure and wired according to the diagram on page 3-11.
2. Use a single fuse in the live line for 1-phase input iDrive models where supply is L+N.
Where L+L supply is to be used, each line must be fused.
For 3-phase input models, each L1(L)/L2/L3(N) phase must be fused or protected by MCCB.
3. A suitable three-phase ‘squirrel cage’ induction motor must be used with iDrive.
4. If an iDrive is to operate more than one motor in parallel, the total operating current should
be less than or equal to the iDrive’s rated output current.
A suitable thermistor should be installed in each motor to protect from winding over-heat.
5. Do not install a capacitor, LC, or RC network between the iDrive and the motor.

3.3.3 Ancillary power equipment – supply side:
Power supply:
• Make sure the voltage applied is correct to avoid
damaging the iDrive.
Moulded-case circuit breaker MCCB:
• Use a MCCB that matches the rated voltage and current of
the iDrive to control the power ON/OFF and protect the
input wiring.
• Do not use the MCCB as the switch for running and
stopping the motor.
Fuse:
• A suitable rated fuse(s) should be installed between the
iDriveand the AC power source to protect the wiring if a
MCCB has not been used.
Earth Leakage circuit breaker ELCB / RCD:
• To prevent error operation caused by filter leakage current
install a RCD with a trip current range of 30mA or
greater, and action time <0.04 seconds. In case of models
EDX-150-21-E and EDX-220-21-E a RCD with trip
current range >200mA should be used.
Magnetic contactor MC:
• If required use a suitably rated magnetic contactor
between the power supply and the iDrive input terminals.
• Do not use the magnetic contactor as the run/stop switch
for the iDrive.
AC Reactor for power improvement ACR:
• When iDrives are supplied with high capacity (above
600KVA) power source, an AC reactor can be installed
between the iDrive and the AC power souce to improve
Power Factor, reduce harmonic currents and increase
short-circuit protection – see page 3-12. An ACR can also
be used on the motor side when cable is very long.
EMC filter:
• Standard iDrive’s have an integrated EMC filter to reduce
electromagnetic interference to other equipment connected
to the same AC power supply.
iDrive:
• Output terminals T1, T2, and T3 are connected to U, V,
and W terminals of the motor.
• To avoid damaging the iDrive, do not connect the motor
terminals T1, T2, and T3 to AC power.
