Insulated transformer
Symbol Name of the component (Note 1) Connect a step-down transformer so that the voltage of the
sequence circuit is as shown in Figure 3.3.6.
(Note 2) Be sure to connect the auxiliary power supply input terminals (R0
and T0) of the PWM converter and inverter to the main power supply
through the “b” contact of the electromagnetic contactor (52) for the
power supply. Additionally, when connecting to a non-grounding
power supply, install an insulation transformer. Refer to chapter
3.3.5(5) for more information.
(Note 3) Since the power for the AC fan of the inverter is supplied from the
R1, T1 terminals, connect the power line to the main power supply
directly, not via the contact point (b) of contactor 52.
(Note 4) Ensure the sequence in which the operating signal is input to the
inverter with the PWM converter set up for operation.

(Note 5) Set the 52T timer to 1 second.
(Note 6) The PWM converter of the digital input terminal (X1) is set to an external alarm (THR), be sure to connect
overheating signal output (1, 2) of the filter stack. In order to set up normal close, set up the function code E14. In
addition, the microswitches for AC fuse blown detection is all of the overheating signal output (1,2) and
microswitches in series, be connected to the digital input terminal (X1).
(Note 7) Match the order of phases when wiring the L1/R, F2/S, L3/T, R1, S1, and T1 terminals.
(Note 8) To input 200 VAC as the fan power, first disconnect the wires between the R11-R12 terminals and between the
T11-T12 terminals, and then connect the wires to the R12 and T12 terminals instead. Please note that these are
dedicated terminals for the internal fan power supply. Do not use for applications other than this.
(Note 9) Be sure to set the 73T timer to 5 seconds.
(Note 10) To use a separate source to power fan, change the tap inside converter, then connect terminal R3, T3 to power
source for fan.
•
The PWM converter of the digital input terminal (X1) is set to an external alarm (THR), be sure to connect
overheating signal output (1, 2) of the filter stack.
•
At the time of the operation of the overheating signal, be sure to stop the PWM converter and the inverter. In
addition, shut off the electromagnetic contactor 52 and 73.
Otherwise, a fire or an accident might result.
