iDrive
Chapter 3 Environment description and installation
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
iDrive and 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.
