(*1) Connect a stepdown transformer to limit the voltage of the sequence circuit to 220 V or below.
(*2) Be sure to connect the auxiliary power input terminals R0 and T0 of the PWM converter and the inverter to the main
power input lines via B contacts of magnetic contactors of the power supply circuit (52). When the PWM converter is to
be connected to an ungrounded power supply, an insulation transformer is required. For details, refer to the PWM
Converter Instruction Manual (INR-HF51746 .
(*3) Connect the auxiliary fan power input terminals R1 and T1 of the inverter to the main power input lines without going
through the MC's B contacts or 73.
(*4) Set fan power supply switching connectors CN R and CN W on the NC and FAN positions, respectively.
(*5) Construct a sequence in which a run command is given to the inverter after the PWM converter becomes ready to run.
(*6) Set the timer 52T at 1 sec.
(*7) Assign the external alarm
THR to any of terminals [X1] to [X7] on the inverter.
(*8) Wiring for terminals L1/R, L2/S, L3/T, R2, T2, R1, S1, and T1 should match with the phase sequence.
