(Special -10 125mA versions available)
During normal powered operation the contacts will be closed. When the unit goes on battery the contacts open and when the batteries run down and disconnect the contacts remain open (NO (Normally Open) means that under no power the contacts are open). Make sure you understand that during "normal" operation the NO contacts will be closed! There is not an -NC version as that is the stock version.

Lead acid batteries used with the BVUPS are on float most of the time and should last about 4 years before losing appreciable capacity. Thus, we recommend the following steps for best practice.
For very large banks of batteries (over 50Ah) There is the STEP-RATE-MODULE to provide higher charge rates for system with more than 50AH It provides two rates: An increased initial charge rate - it then Transitions to float rate at 13.1 or 26.9V with an increased float current.
Orange wire connects to pin 3 and the Blue wire to Pin 6 of the octal socket.
