Chapter 10 Options
10-1.Options
If the extended function (such as RS485 card, PG card, etc.)for other functional
modules is needed, please specify the functional module card you want when ordering.
10-2.Molded case circuit breaker (MCCB) or earth leakage circuit
breaker (ELCB)
MCCB or ELCB as the power switch of the inverter also plays a protective role to
the power supply. Note: do not use MCCB or ELCB to control start/stop of the
inverter.
10-3.AC input reactor
AC input reactor can inhibit high harmonics of the inverter input current,
significantly improving power factor of the inverter. It is recommended that AC input
reactor should be used in the following cases.
The ratio of the capability of power supply used for the inverter to the inverter
own capability is more than 10:1.
The thyristor load or the device of power-factor compensation with ON/OFF is
connected with the same power supply.
The degree of unbalance for three-phase power supply voltage is larger (≥ 3%).
Dimensions for common specifications of AC input reactor are as follows:
