Operating the PS2/3/5
5.1 Setting the DIP Switches (Non-Listed supplies only)
Before powering a system containing a PS2/3/5, the DIP Switches should be set for proper operation.
The PS2/3/5 board may have either 4 switches or 8 switches, depending on the age of the supply.
Note - Due to inconsistencies by the manufacturers of DIP switches in the labeling of switch numbers
and ON and OFF positions, AlarmSaf indicates switch settings visually and descriptively.
Note - All switch settings shown below are indicated with the board positioned so that the terminal
strips are to the right and the large heatsink is to the left as seen in Figure 5.1.
