Instruction manual

When connecting a PWM converter with an inverter, do not connect the power supply line directly to terminals
R0 and T0. If a PWM is to be connected, insert an isolation transformer or auxiliary B contacts of a magnetic
contactor at the power supply side.
For connection examples at the PWM converter side, refer to the PWM Converter Instruction Manual.
Figure 2.9 Connection Example of PWM Converter
Auxiliary fan power input terminals R1 and T1
Inverters of 60 HP or above for 230 V and those of 125 HP or above for 460 V are equipped with terminals R1 and T1.
Only if the inverter works with the DC-linked power input whose source is a PWM converter, these terminals are used
to feed AC power to the fans, while they are not used in any power system of ordinary configuration.
In this case, set up the fan power supply switching connectors (CN R and CN W).
Terminal rating:
200 to 220 VAC/50 Hz, 200 to 230 VAC/60 Hz, Maximum current 1.0 A (230 V series with 60 HP or above)
380 to 440 VAC/50 Hz, 380 to 480 VAC/60 Hz, Maximum current 1.0 A (460 V series with 125 to 800 HP)
380 to 440 VAC/50 Hz, 380 to 480 VAC/60 Hz, Maximum current 2.0 A (460 V series with 900 and 1000 HP)
