This guide is to assist in installing and running the inverter to verify that the drive 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 starting the inverter
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 start 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 .

3.3.3 Ancillary power equipment – supply side:
Power supply:
Make sure the voltage applied is correct to avoid damaging the
inverter.
If possible install a suitable moulded-case circuit breaker
between the AC power source and the inverter.
Moulded-case circuit breaker MCCB:
If possible use a moulded-case circuit breaker that conforms to
the rated voltage and current of the inverter to control the power
ON/OFF and protect the inverter.
Do not use the inverter as the switch for run/stop switching.
Fuse:
Asuitable rated fuse(s) should be installed between the inverter and
the AC power source to protect inverter if a MCCB has not been used.
Earth Leakage circuit breaker ELCB / RCD:
If required, install an RCD to prevent error operation caused by
leakage current and to protect operators. If possible use trip
current range >200mA and action time >0.1 seconds.
Magnetic contactor MC:
If required use a suitably rated magnetic contactor. But a
contactor has to be installed when performing functions such as
external control and auto restart after power failure, or when
using brake controller.
Do not use the magnetic contactor as the run/stop switch for the
inverter.
AC Reactor for power improvement ACR:
When inverters are supplied with high capacity (above
600KVA) power source, an AC reactor can be installed between
the inverter and theAC power souce to improve Power Factor and
reduce harmonic currents. Can also be used on the motor side
when cable is very long. See next page.
EMC filter:
Standard iDrive EDX inverters have an integrated EMC filter to
reduce electromagnetic interference to other equipment connected
to the same ACA power supply.
Inverter:
Output terminals T1, T2, and T3 are connected to U, V, and W
terminals of the motor.
To avoid damaging the inverter, do not connect the input
terminals T1, T2, and T3 to AC power.
