The APU Engine On/Off Swi ch is loca ed inside he TriPac 3 APU housing on
he lower righ side of he frame. The Engine On/Off Swi ch func ions as a
service swi ch o allow main enance personnel o preven he APU engine
from s ar ing when working on he uni . The swi ch is normally in he ON
posi ion o allow he TriPac sys em o opera e. When he Engine On/Off
Swi ch is placed in he Off posi ion , i will no only preven he engine from
s ar ing, bu disable ALL ou pu s in he sys em (fans, AC clu ch, e c.) from
