  • Page 3: Safety Precautions

    SAFETY PRECAUTIONS Carefully read this manual and all of the warning labels attached to the inverter before installing, operating, maintaining, or inspecting it. Safety precautions are classified into “Warning” and “Caution” in this manual. : Indicates a potentially hazardous situation which, if not avoided, can result in serious injury or WARNING death.
  • Page 4 Otherwise, there is a danger of electric shock and/or fire. Maintenance, Inspection and Part Replacement: Wait at least 10 minutes after turning off the input power supply before performing maintenance and inspection. (Confirm the charge lamp on the inverter is off, checks direct current voltage between P-N terminals and confirm it is less than 45V.)

Make sure to input classification code in order, higher code and then lower code. 5.3 DATA INPUT TIMING 5.3.1 TIMING AT ONE TIME INPUT Take in data in on level that strobe signal. Let on/off time of strobe signal be more than 20ms. Be in state of on. And if data indefinite area is more than 5ms, turn strobe signal off in order to satisfy Figure 5.3.1 timing chart of one time data input.
  • Page 19 5.4 NOTICE AT DATA INPUT While inputting the data by terminal of SJ-DG, notice the following items. (1) Each input is possible to set within data range of the inverter in every setting item. If inputting without data range, sequence error is outputted and data input is invalid (previous data is kept).
