PROBLEM TO BE SOLVED: To eliminate the wiring work for installing a display unit by converting a data signal to a wireless signal and then transmitting the converted signal and then receiving the wireless signal and displaying the operational condition of an inverter section based on the received signal. SOLUTION: The data signals corresponding to the output current value and output voltage value of a DC/AC converter 9 which show the operational condition are output to an antenna ANT1 via a transmission circuit 10b and then the data signals received by the antenna ANT1 are transmitted as electric wave signals from the antenna ANT1. The electric wave signals transmitted by the ANT1 are received by an ANT2 and the electric wave signals are converted to the output data of a CPU circuit of a system-linked controlling circuit 12 by means of a receiving circuit 10e and the output data is input into a display controlling circuit 10f and finally, the content of the operational condition of the AC/DC converter 9 is displayed on a display device 10h. By this method, the wiring work for installing a display unit can be eliminated. |
