I spoke with the company electrician the other day, a very skilled man. He was on our ship doing some maintenance on our converters, where he also changed the batteries for the PLC. He said if I removed the power supply and changed the battery, the PLC would not work when we were to start it up again. But som PLC's could handle the power loss.
