HJP1 Jumper Operation If you don’t install a jumper, or if you install the
jumper between pins 1 and 2 (SW), the
hazardous interface operates in switched
mode. If you install the jumper between pins 2
and 3 (UNSW), the hazardous interface
operates in unswitched mode. Figure 2-1
shows the jumper in switched mode.
