To ensure effective noise reduction when

from the filter must go to the auxiliary

control-power input terminals.

If these terminals are connected to the input side of the filter, the noise reduction effect deteriorates.

When the RCD (Residual-current Protective Device) is installed (G11S:30HP or less), the terminal R0 and T0 should be connected to the OUTPUT side of the RCD. If they are connected to the input side of the RCD, RCD will be malfunction because the power supply of the inverter is three phase and the terminal R0 and T0 is single phase.

When the terminal R0 and T0 are connected to the INPUT side of the RCD, the insulation transformer is required to install as shown on the Fig. 2-3-5.

(4)DC reactor connecting terminals (P1 and P (+))

Before connecting a power-factor correcting DC reactor (optional) to these terminals, remove the factory-installed jumper.

If a DC reactor is not used, do not remove the jumper.

Note:For inverter of 100HP or more, the DC reactor is provided as a

 

separate standard component and should always be connected to the

Fig. 2-3-6

terminals.

(5)External braking-resistor connecting terminals (P (+) and DB) (G11S:10HP or less)

For the G11S of 10HP or less, a built-in braking resistor is connected to terminals P (+) and DB.

If this braking resistor does not provide sufficient thermal capacity (e.g., in highly repetitive operation or heavy inertia load operation), an external braking resistor (option) must be mounted to improve braking performance.

Remove the built-in braking resistor from terminals P(+)

(6) DC link circuit terminals (P (+) and N (-))

The G11S inverter of 15HP or more does not contain a drive circuit for the braking resistor. To improve braking

performance, an external braking unit (option) and an external braking resistor (option) must be installed.

Connect terminals P(+) and N(-) of the braking unit
