Technical Handbook
Safety Hazards, Warnings And Cautions
2.3.3 Antistatic Precautions
As with all modern electronic circuits, the Printed Circuit Boards (PCBs) in Touchpoint Plus systems utilize
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 differing electrical potential.
Static damage is not always immediately apparent and can 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 shipped in 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 fibers. 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.
If installed correctly, the equipment earth (ground) point is connected directly to mains earth (ground) via
protective earth and the mains power supply cable. It is not dependent on the position of the Isolator switch or
Important
circuit breaker.
2.3.4 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.
2.3.5 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.

The system can be directly wall-mounted or on an optional mounting fixture. Whichever method is chosen, the
mounting must be sound, secure, and capable of supporting the weight of the enclosure plus the weight of
any cables and glands.
When choosing a location, it must be easily visible and accessible, with room to mount an external power
isolator. There must also be room to fully open the access door, which opens to the left, and room to easily
access the door locking handle and its securing screws, which are situated on the right. If using the expansion
unit (available late 2015), there must be room to mount both boxes side-by-side with space between them to
access the locking handle and its securing screws.
The units should be mounted so that the screen can be easily accessed and seen, but they should not
obstruct accesses, walkways or exits.
Although the units are IP65 when installed correctly, they should be mounted away from heat sources, out of
direct sunshine, and should be protected from rain, severe weather, steam or excess humidity and
condensation.
These units have only passive cooling, so an adequate airflow must be maintained to prevent overheating.

5) Closure is the reverse of this procedure, but care must be taken not to exert undue force, and you must
not press on the membrane or touch screen areas.
Note: The door recess has an environmental seal that requires some pressure to close the door correctly.
The enclosure handle is the primary method of applying this pressure but you can assist it by pressing on the
door edge directly above the handle as you press on the handle itself.
