Safety Switch Assembly - InFocus LP340B Service Manual

Safety Switch Assembly

The safety switch assembly (526-0049-xx) contains two switches. The thermal switch shuts the projector
down if the lamp becomes too hot. The interlock switch prevents the projector from operating when the
lamp door is removed. The switches fasten to the top and side of the lamp housing. The assembly
includes a cable that attaches to the high voltage power supply.
The safety switch assembly comes with a new lamp housing, as well as with a new optical engine.
WARNING! Make sure the power cord is not plugged into the unit when you begin working on the inside of the
projector.
1 Remove the chassis and attached parts from the top case (see page 28).
2 Place the chassis upside down on a soft, ESD-protected surface.
3 Disconnect the safety switch assembly cable from its connector on the low voltage power supply.
4 Remove the two Phillips screws that fasten the interlock switch to side of the lamp housing.
