SAFETY

SAFETY NOTES:

- Connections to or from any electrical device must never be made while the device is switched
on.

- The Oriel Model 68805 Power Supply is such a device. It has an open circuit voltage of >160
volts when the start switch is pressed, and could be dangerous if care is not exercised when the
power supply is switched on. Please follow these precautions when operating the power supply:

Make all input and output connections before turning the power supply on.

Do not use the power supply without its cover.

Ensure that the output terminals are properly connected to the lamp housing or
lamp socket before turning on the power supply.

Don't open the power supply or disconnect the output leads while the power
supply is on.

- Follow the lamp or lamp house manufacturer's recommendations and precautions when handling
and using lamps.

- Never touch the lamp's quartz envelope with uncovered fingers; definitely not when operating
the lamp or immediately after shutdown. Also, follow this precaution during lamp installation to
avoid damage to the lamp.

- Do not start the lamp with the output control set above the current rating for the lamp.

- The lamp is a source of constant current. To prevent overpowering of the lamp as it ages,
monitor its current on regular basis.
