Connecting to an uninterruptible power supply

An uninterruptible power supply (UPS) allows the projector head electronics to remain operable during
a power failure.
Warning! If not avoided, the following could result in death or serious injury.
• SHOCK HAZARD! The optional UPS power cord must be inserted into an outlet with grounding.
The UPS is connected through the 12V power supply on the projector. The following illustration shows
the power supply and connections.
