Salut, de unde pot cumpara sau cine ma poate ajuta cu un cablu serial pentru accesarea unui UPS APC Smart-UPS 620VA? Am vreo 2 cabluri seriale prin casa dar nu functioneaza, probabil ca sunt niste pini inversati...
Eu l-am calibrat pe al meu ultima dată cu un fierbător și o oală cu apă . Totuși nu-s sigur că merge la schimbarea acumulatorilor.Manual Calibration:
- This is the preferred method for "SU" series Smart-UPS, or any time that a User Commanded Calibration is not possible
- Stop the Power Chute software from running and disconnect the serial, USB, or Ethernet cable(s).
- There must be at least a 30% load attached to the UPS during this procedure, and this load cannot fluctuate more than +/- 5%. THIS IS IMPORTANT
- Attach a non-critical load to the UPS and then force the UPS on battery by disconnecting it from utility power
- Allow the unit to run on battery until it turns off completely. The load attached to the UPS will drop.
- If the Load is not at least 30% or if the calibration is ended before the UPS drops the load, the calibration will not work.
- Plug the UPS back into the wall outlet and allow it to recharge (preferably turned off)
