GENERAL INFORMATION

Safety

WARNING

CAUTION

This unit emits ultraviolet (UV) radiation that is

harmful to humans. Avoid exposure to the

direct or reflected output beam. Make certain

that the appropriate output beam shields and

optics are in place prior to energizing the unit.

All interlocks must be satisfied prior to

operation; failure to do so may lead to

hazardous conditions.

The EQ-400 emits dangerous levels of UV

radiation. Even short exposures to skin or eyes

may cause burns. Ensure that only authorized

personnel are in the vicinity of source during

operation. Personnel in vicinity of operating

source should wear protective eyewear, clothing,

and gloves. Lighted UV warning lights and signs

posted on doors to lab areas may help prevent

accidental exposure.

WARNING

General Precautions

The output beam from the EQ-400 should be blocked when not in use with an electronic

shutter or other appropriate beam blocking device. Due to the possibility of generating ozone

with some models of EQ-400 when ambient oxygen is exposed to short wavelength light, the

beam should always be enclosed in an appropriate beam pipe, tube, or enclosed space. We

suggest purging any beam transport space with dry nitrogen gas.

The EQ-400 source must also be cabled correctly and connected to a power source with a

protective earth ground prior to operation.

Refer to the Installation section of this manual in Chapter 3 for details of the facilities

connections.

There are no user-serviceable parts inside the EQ-400. For any problems encountered during

operation, please contact Energetiq Technology for assistance. If there is a component

failure, do not attempt to open the Power/Control Unit or Lamp House enclosure of

the EQ-400.

No regular maintenance is required for the EQ-400. Any service to the system must be

performed only by factory authorized and trained technicians. To avoid injury, under no

circumstances should the user open or modify the Lamp House or Power/Control Unit

enclosure.

The unit must not be operated if the covers are removed or it is defective in any way. Contact

Energetiq if any problems with the equipment are suspected.

The EQ-400 utilizes a quartz lamp containing a high-pressure gas fill. Explosion of

the lamp and possible injury from flying fragments can occur if the lamp is

mishandled.

Do not open the enclosure of either the Lamp House or the Power/Control Unit.

Dangerous invisible infrared laser beams and hazardous voltages exist inside the

Lamp House. Opening the chassis both voids the warranty and exposes the user to

dangerous radiation and hazardous voltages.

The EQ-400 utilizes an internal Class 4 IR laser

capable of causing severe injury to eyes or skin.

Do not open or attempt to service this unit.

Contact Energetiq regarding any problems with

the unit.

CAUTION

The EQ-400 is a Class 4 Laser Product. All appropriate laser safety measures should be in

place before operating the system. Consult your facility's laser safety officer. Laser protective

eyewear should be worn at all times while operating the system.

The EQ-400 also produces high-intensity UV radiation. Eyewear should protect not only from

laser radiation at 1070 nm, but also from UV radiation in the band from 190 to 400 nm.

For further safety information, refer to ANSI Z136.1 Standard for Safe Use of Lasers,

available from Laser Institute of America (www.laserinstitute.org).

Laser Information

The EQ-400 uses a patented* laser drive system to excite a plasma that radiates in the UV as

well as the visible bands. A Class 4 laser is located in the Power/Control Unit enclosure. The

optical configuration of the Lamp House ensures that the direct laser beam cannot exit the

unit. The EQ-400 laser product is designated as Class 4 during all normal operation.

The parameters of the non-accessible internal laser are given below in Table 1.

Nominal Ocular Hazard Distance (NOHD) based on 400W 1070nm pump laser under a

failure mode condition where aperture is itself accessible: 4 meters

Required Optical Density (OD) for safety eyewear: 6 or higher at 1070 nm

These values are based on a theoretical failure condition.
