ANTI-STATIC HANDLING
HANDLING OF ELECTROSTATIC-SENSITIVE SEMICONDUCTOR DEVICES
Certain semiconductor devices used in the equipment are liable to damage due to static voltage. Observe the following
precautions when handling these devices in their un-terminated state, or sub-units containing these devices:
Persons removing sub-units from equipment containing these devices must be earthed by a wrist strap and a resistor at the
labelled point provided on/within the equipment.
 Soldering irons used during authorised repair operations must be low voltage types with earthed tips and isolated from the
mains voltage by a double insulated transformer.
 Outer clothing worn must be unable to generate static charges.
 Printed circuit boards fitted with these devices must be stored and transported in anti-static containers.
 Fit new devices in a special antistatic safe handling area.
Fully isolate and mechanically disconnect all sources of AC before attaching ESD protective wrist straps to the various points in
the system.
RoHS STATEMENT
For details on RoHS statements please contact Kelvin Hughes; contact details can be found in at the end of this handbook.
END OF LIFE DISPOSAL
When the equipment detailed in this handbook has reached the end of its serviceable life, the various parts that make up the
system must be disposed of in accordance with local industrial waste disposal regulations.
Please contact your local regulatory body for disposal instructions or contact Kelvin Hughes for a list of any potentially hazardous
material contained within the system.
SharpEye™ specific disposal notice: The SharpEye™ transceiver(s) located within the turning unit/gearbox are factory sealed
units that contains no field serviceable parts or lifed components. Components within the SharpEye™ processor (all variants)
contain traces of beryllium and trivalent chromium. Please contact Kelvin Hughes regarding the repair of a SharpEye™ or its
end of life disposal instructions. Contact details for Kelvin Hughes can be found at the end of this handbook.
GROUNDING/EARTH POINTS
All parts of the system must be fully and correctly connected to a proven earth point prior to connecting any source of AC power.
WARNING
DO NOT OPERATE WITH EARTH DISCONNECTED
The system must NOT be operated or have AC power switched ON with any earth/grounding points disconnected
Connection point: All Kelvin Hughes equipment is fitted with a single protective earth connection point which is indicated on
the mechanical installation drawings.
Conductivity tests: During installation and maintenance, the earth connections must be tested for conductivity using a high
current impedance meter such as a Megger or similar.
Wrist Straps: Fully isolate and mechanically disconnect all sources of AC before attaching ESD protective wrist straps to
the various points in the system.
SERVICING AND REPAIR
CAUTION: LIFTING SPARES
Where spare parts are required for equipment located on a platform or access is via a ladder, heavy items must be lifted to the
platform using a suitably rated lifting bag or lifting strop.
Heavy items must not be manually carried up ladders as they can present a drop hazard.
Service and equipment repair must only be undertaken by Kelvin Hughes or a Kelvin Hughes authorised service agent/engineer.
Un-authorised repair or servicing of equipment during the warranty period may invalidate the warranty status of the equipment.
