A---3 Appendix

Frequency of Sources

DIP switch actuator 7 selects either 50 or 60 Hz source frequency. See Table C.

Data Input Lock

The Group 5 controller has an external input for a dry contact that, if closed, prevents setting changes from the keypad. DIP switch actuator 10 selects either yes or no for the external input (such as a key switch). Placing DIP switch actuator 10 in the Yes position enables the controller to respond to the external input. See Table F.

Phases of Normal & Emergency Sources

DIP switch actuators 8 and 9 select either 1 phase or 3 phase for the Normal and Emergency sources. See Tables D and E.

Lost or Forgotten Password

Moving DIP switch actuator 10 to the Yes position will allow a new password to be input (as long as the external input is open). Once the new password has been entered, return DIP switch actuator 10 to the No position. See Table F.
