2.3 Electrical Hazards
Gas detection systems contain electrical supplies that are potentially dangerous and hence suitable precautions
must be taken to prevent the risk of electrocution. This is especially important when untrained/unqualified persons
are allowed to open the enclosure (e.g. to access/remove/refit the SD Card).
2.3.1 General Safety Precautions
•Read the relevant manual before beginning any operating or service procedures.
•Only personnel trained andcertified by Honeywell are authorisedto service, fit or remove internal parts.
•Only the minimum number of trained personnel, consistent with safety, should have access to the area while work
is being carried out. If necessary, erect warning signs and barriers.
•Follow accepted working procedures andcodes of practice as well as the electrical safety code for the site where
the equipment is installed.
•Never operate the equipment under normal conditions with doors open, access panels removed or shorting links
fitted.
•
•Always keep the area around the equipment dry and free of obstructions.
•Switch off and Isolate the equipment if water ingress is suspected or confirmed.
•Never operate the equipment if any Mains power cable is frayed or damaged.
•Never wear wristwatches, rings, bracelets, or other jewellery when working around electrical circuits or moving
parts.
•Take anti-static precautions when working on electronic circuits.
•Never work on electrical equipment alone.
2.3.2 Component Testing and Replacement
Before carrying out any electrical testing or component replacement:
•Read this Manual to become familiar with the location of highvoltage components.
•Off
maintenance work is in progress.
•Always wait for 5 minutes after isolating the equipment to ensure that stored energy has dissipated.
•Never assume the polarity of cabling or replacement components. Refer to electrical schematics or contact
Honeywell for confirmation.
•Use only Honeywell approved replacement parts.
WARNING UNAUTHORISED PERSONNEL
Only Honeywell trained and certified maintenance technicians are authorised to carry out component testing
and replacement. Unauthorised work may result in a potentially dangerous situation and will invalidate the
ANTI STATIC PRECAUTIONS
Antistatic Precautions are required to prevent severe damage to electronic components.

MAN0984_Iss 4_01/19 Touchpoint Plus
Pt. No. 3011M5001 18 Technical Handbook
Antistatic Precautions
As with all modern electronic circuits, the Printed Circuit Boards (PCBs) in Touchpoint Plus systems utilise some
static-sensitive components that can be severely damaged if subjected to static discharge. Static can be generated
on the human body by friction or movement and is discharged through the first contacted route to earth. It can also
jump gaps between items of differingelectrical potential.
Static damage is not always immediately apparent andcan cause component failure at any time after the static
discharge has occurred. It is, therefore, very important that everyone takes the following precautions when handling
PCBs:
•An industry approved antistatic wrist strap, containing a resistive component greater than 1Megohm, must be
worn and connected to an effective earth (ground) point. The continuity between the strap and earth (ground)
must be checked regularly.
•PCBs must only be handled by their non-conductive edges. Do not allow any components, conductive tracks or
contacts to come into proximity with the body, clothing, machinery, power source or any material other than a
static-dissipative mat.
•With the exception of assemblies containing batteries, anti-static packaging must be used for transporting PCBs
and Integrated Circuits (ICs). All Touchpoint Plus electronic components are shippedin appropriate packaging
that can be re-used when returning items for test or repair.
•Avoid wearing clothing manufactured from, or containing a high proportion of, man-made fibres. These can build
up a high static potential that may not be discharged through the body or wrist strap.
An effective earth (ground) point is the protective earth (ground) bus bar inside the enclosure. This can be used to
connect a suitable anti-static wrist strap provided that the Gas detection system is connected to protective earth
(ground) via the mains power supply cable.
2.3.3 Good Practice
After switching off the system, it is good practice to wait at least 15 seconds before switching it on again. This allows
the circuits and RAM to discharge adequately before being powered-up again. Failing to do so may cause data
corruption.
2.3.4 Lithium Battery Hazard
Lithium batteries are fitted to Touchpoint Plus as backup power sources.
Replace the factory installed battery pack TPPLOIBB with Honeywell Analytics Asia Pacific replacement battery pack
part no. TPPLSIBB and the PCB CMOS battery with type CR2032 only.
Use of other batteries may present a risk of fire or explosion.
IMPORTANT
If installed correctly, the equipment earth (ground) point is connected directly to mains earth (ground) via
protective earth and the mains power supply cable, and the earth (ground) circuit cannot be broken by
operating the Isolator switch or circuit breaker.
LITHIUM BATTERY TOXIC AND FIRE HAZARDS
Lithium batteries may cause severe injury or death if swallowed, and may catch fire or explode if mishandled,
recharged, burned or disposed of incorrectly.
Always handle lithium batteries with care, keep them out of the reach of children, and dispose of them
carefully in accordance with local regulations.
Batteries shall only be fitted, removed or replaced in non-hazardous (safe) areas.
