1.1 Qualified Personnel
The LYNXEYE XE™ may only be set up and operated in conjunction with this manual. Only personnel
authorized by Bruker AXS is allowed to work on this equipment. All repairs, adjustments and align-
ments performed on any components of the LYNXEYE XE must be carried out strictly in accordance
with the established safety practices and standards of the country where the equipment is installed.
1.2 Correct Usage
This device and its components may only be used for the applications described in this manual and
only in connection with devices or components from other manufacturers which have been approved
or recommended by Bruker AXS.
This product can only function correctly and safely if it is transported, stored, set up and installed cor-
rectly and operated and maintained as recommended by Bruker AXS. Protection provided by this
equipment may be impaired if it is used in a manner not specified by Bruker AXS.
1.3 X-ray Equipment
Warning
X-ray equipment produces potentially harmful radiation and can be dangerous to anyone in
the immediate vicinity unless safety precautions are completely understood and imple-
mented. All persons designated to operate or perform maintenance need to be fully trained
on the nature of radiation, X-ray generating equipment and radiation safety. All users of the
X-ray equipment are required to accurately monitor X-ray exposure by proper use of X-ray
dosimeters.
For safety issues related to the operation and maintenance of your particular X-ray generator, diffrac-
tometer and shield enclosure, please refer to the manufacturer operation manuals or your Radiation
Protection Supervisor. The user is responsible for compliance with local safety regulations.
The LYNXEYE XE detector itself is no source generating X-rays, it just senses X-rays.

Warning
Voltage Danger - Before installing the detector, switch off the system to avoid high voltag-
es.
Bias voltages up to 500 V DC are accessible from the outside! They are present on the
metal sensor window on the front side of the detector! Never operate the detector with Bias
voltage switched on without having the detector optics mounted!
Inside the LYNXEYE XE, Bias voltages up to 500 V DC can occur which are not accessible
from the outside. After turning off the system, Bias voltages are still present. They dischar-
ge over time.
Warning
Sometimes complex D8 systems will be supplied by several power supply lines. The sys-
tem and its components will be live until all power lines connected to the system are dis-
connected from the mains power supply.
Caution
Switching ON/OFF the detector Bias will initiate a ramping process for the Bias voltage.
This process is indicated by a flashing BIAS READY LED. In all cases wait until the ramp-
ing process has finished.
When switching ON the detector Bias this will be indicated by a steadily lit BIAS READY
LED.
When switching OFF the detector Bias this will be indicated by the BIAS READY LED turn-
ing off.
Any violation of this precaution rule might result in a reduced lifetime or damage of the de-
tector.
Caution
Never touch the metal sensor window of the detector entrance window with fingers or tools.
Any partial damage on this thin layer might lead to non-repairable malfunctions of the de-
tector; the warranty is not valid any more.

Caution
Use care when moving the detector head to avoid mechanical shock to the assembly.
1.4 Proper Lifting
Installation of the detector requires lifting of components with heavy weight (e.g. enclosure front pan-
el). Whenever possible, two or more people should lift objects together. Use proper lifting techniques
at all times. Use the following steps as an overview of proper lifting techniques.
1. Plan: practice the lift. While lifting, bend at the knees, keep your back straight, tighten your stomach
and lift with your legs.
2. Position: keep your body close to the object you wish to lift - your stability increases the closer you
are to the object. Keep your feet shoulder width apart.
3. Movement: avoid making awkward movements while holding a heavy object. Get help if the object
is too heavy or cumbersome.
