removed:
 Turn off the external AC breaker and/or system disconnect switch using lock-out/tag-out procedures.
 Turn off the external DC breaker and/or disconnect switch, if present, and use lock-out/tag-out
procedures. (Skip this step if there is no DC circuit breaker.)

 Switch the inverter's DC disconnect switch to "OFF" position.
 Wait for 5 minutes to ensure the internal capacitors have been completely discharged.
