    NOTE • Installing the fan in the opposite direction of air flow may shorten the converter unit life. • Ensure that the cables are not caught when the fan is installed. • Switch OFF the power before starting the fan replacement work. Before starting the replacement, power OFF the converter unit, wait for at least 10 minutes, and then check that the charge lamp is OFF to prevent an electric shock accident as the converter unit circuits are charged with voltage even after power OFF.

    7.1.7 Removal and reinstallation of the control circuit terminal block This product has a removable control circuit terminal block, which can be replaced with a new one.  Removal and reinstallation Loosen the two installation screws at the both sides of the control circuit terminal block. (These screws cannot be removed.) Slide down the control circuit terminal block to remove it.
  • Page 189 NOTE • Do not tilt the terminal block while tightening the screws or removing it from the product. (Otherwise, stress applied to the control circuit terminal block or the control circuit connector may damage the pins.) • After replacing the control circuit terminal block, connect the jumper connector to the correct position in accordance with the control logic of input signals.

  • Page 190: Measurement Of Main Circuit Voltages, Currents, And Powers

    Measurement of main circuit voltages, currents, and powers Since the voltages and currents on the converter unit power supply and output sides include harmonics, measurement data depends on the instruments used and circuits measured. When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments given on the next page.
