maintenance to your system.
lTo prevent injury to you and damage to the equipment, obey the precautions in this
manual.
lAll specifications and illustrations are for reference only and were complete and
accurate as of the release of this manual. To find the newest information about this
product, refer to www.aerotech.com.
If you do not understand the information in this manual, contact Aerotech Global
Technical Support.
IMPORTANT: This product has been designed for light industrial manufacturing or
laboratory environments. If the product is used in a manner not specified by the
manufacturer:

lInstall the necessary precautions to supply safety and protection to the operator.
lIt is the responsibilty of the system integrator or qualified installer to determine and
meet all safety and compliance requirements when they integrate the AGV-HP(O)
into a completed system.
IMPORTANT: The protective ground connection of the AGV-HP(O) provides motor
frame ground protection only. Additional ground and safety precautions are required
for applications that require access to the AGV-HP(O) while it is energized.
DANGER: Use of this product increases the risk of exposure to visible and/or invisible
laser radiation.
lDo not stare into the laser beam, put your body parts in the laser area, or expose
yourself to reflections from powerful beams.
lWear certified laser safety eye protection.
lAvoid eye or skin exposure to direct or scattered radiation.
DANGER: High pressure air can cause severe injury.
lLock out the source and bleed off the pressure before you do service to the equip-
ment.
lWear eye protection.
lWear ear protection.
WARNING: To prevent damage to the equipment and decrease the risk of electrical
shock and injury, obey the precautions that follow.
lOnly trained operators should operate this equipment.

IMPORTANT: Carefully lift, move, and transport this product.
IMPORTANT: Fingerprints contain aggressive substances that can damage optical
surfaces. Wear clean, powder-free gloves when you handle optical components.
Laser Safety
It is the responsibility of the user to provide the necessary conditions for safe operation of a laser
system and to safeguard the work area against the dangers that can be caused by laser radiation.
The user must ensure compliance with all local and national regulations.
Although the scan head by itself does not emit laser radiation, the user must undertake a thorough
analysis of system safety before they operate the AGV-HP(O) in conjunction with a laser source.
Important information for performing this analysis is presented in this manual. Look for additional
information in the corresponding documentation supplied by the manufacturer(s) of the laser
source and other system components.
Classes of Lasers
The AGV-HP(O) series scan head can be used with a variety of lasers. Each laser is assigned a
particular hazard level, which is indicated by the Laser Class label that is affixed to the device near
the location where laser radiation is emitted. Brief descriptions of each of the various radiation
classes are presented in the table below.
Note that in addition to the dangers of radiation, lasers can pose further dangers, such as the risk of
electrical shock or the generation of poisonous fumes.
Classifications of Laser Devices
Class Danger
Class I Inherently safe; no possibility of eye damage during normal operation.
Class IIa Requires in excess of 1000 seconds of continuous viewing to cause eye
damage.
Class II The blink reflex will prevent eye damage, unless the person deliberately
stares into the beam for an extended period of time.
Class IIIa
Mostly dangerous in combination with optical instruments which
change the beam diameter or power density. However, even without
optical enhancement, direct contact for over two minutes could cause
eye damage.
Class IIIb Direct exposures of 0.01 second or less could cause eye and skin
damage.
Class IV Direct or scattered radiation without optical enhancement could cause
eye and skin damage.

Laser Area
The area in which the maximum permitted radiation value can be exceeded is defined as the laser
area. In general, a laser area is applicable to Class IIIa, IIIb and IV laser systems. A laser area can also
be produced if you focus the beam of a Class I, IIa, or II laser device.
The AGV-HP(O) can aim the laser beam over an approximately pyramidal volume. When the scan
head is used in conjunction with a laser device that can generate a sufficiently intense beam, a laser
area will be produced that includes the aiming volume as well as the reflections from all objects that
can be exposed to the radiation. It is important to note that even apparently diffuse surfaces can
reflect laser radiation and a laser beam that has been reflected several times can still be dangerous.
The laser area must be designated by suitable warning signs or lamps and protected by appropriate
shading and interlock switches.
