Ancillary Power Equipment - Supply Side - IMO iDrive Instruction Manual

3.3.3 Ancillary power equipment – supply side:
Chapter 3 Environment description and installation
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:
A
suitable 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.
