Warnings - Honeywell Touchpoint Pro Technical Handbook

1.2 Warnings

Read the following Warnings and Cautions before starting any work on the TPPR system.
1. For safety reasons this equipment must be operated by qualified personnel only. Read and understand the
Instruction Manual completely before operating or servicing the equipment.
The equipment specified in this manual is only to be installed by the Manufacturer's trained personnel, or by
2.
competent persons trained in accordance with the Manufacturer's installation instructions.
3. Installation must be in accordance with the recognized standards of the appropriate authority in the country
concerned. Refer to local, national and company regulations.
4. To protect against cyber threats, installation on a computer network must be carried out in collaboration with
your Company's IT department or professional IT consultants, and the guidelines and recommendations in the
Honeywell Network Security Guide should be followed.
5. Do not operate the Touchpoint Pro system or its components outside of their rated operating specification.
6. Touchpoint Pro must not be operated in Oxygen enriched atmospheres, i.e. greater than 25% v/v Oxygen.
7. All equipment containing a User Interface must be suitably protected from direct sunlight and rain.
Power Supply Fluctuations are not to exceed DC 18 – 32 V SELV Supply or ±10 % of nominal.
8.
9. All versions of Enclosure are electrical Class 1, and must be connected to Protective Earth (Ground).
10. The Touchpoint Pro installation must include a means of isolating or disconnecting the input voltage supply.
The isolation or disconnection device must be conveniently located close to the system and be clearly labelled.
For an AC mains voltage supply, the isolation or disconnection device must disconnect both the line and neutral
poles, but maintain earth (ground) continuity.
11. The Touchpoint Pro input voltage supply must include over-current protection.
12. All cabling must be appropriately rated and approved in accordance with local, national and company
regulations, and suitable for the installation. Additionally, cabling must satisfy requirements defined in the
manuals of connected field devices, in particular if the field device is certified for use in a hazardous location.
13. All signal cables and interconnections must be shielded and the shields terminated only at the unified earth
(ground) bus bar situated inside the enclosure.
14. All conduits and cable armour shall be bonded to protective earth (ground). To avoid ground loops, isolating
cable entry glands shall be used at the enclosure end where conduits or armour are earthed at the sensor end.
15. Cable entry glands, blanking plugs, reducers, adaptors and breather devices must be suitably approved and
must not reduce the IP rating or protection levels. Items should not be used if there is a high risk of mechanical
damage to the equipment or enclosure.
16. Cable gland plates or blanking plates must be installed using the supplied gaskets and metal fixings. Failing to
do so will invalidate the IP rating.
17. Access doors and entry points must not be opened when a flammable gas atmosphere is present (Class 1
Div.2, Class 1 Zone 2, and Zone 2 [ATEX]).
18. Access doors and entry points must be kept closed when the system is energised in normal operation.
19. All equipment in this manual is rated to +2000 m (6562 ft.) altitude maximum.
20. Touchpoint Pro systems may contain hazardous live terminals. Appropriate precautions should be taken during
operation, installation, and maintenance and servicing. Specifically, operators must have appropriate training
and experience to be aware of the hazards to which they may be exposed, and of measures to minimise risk to
themselves or other people.
21. The protection provided by the equipment may be impaired if the equipment is used in a manner not specified
or authorised by the manufacturer. This includes being connected to an insecure TCP/IP network.
22. Be aware that extended exposure of a sensor element to certain concentrations of combustible or toxic gases in
air can introduce stress to the element that may seriously affect its performance, and therefore recalibration
should be carried out or the sensor replaced, or both, after an alarm due to an indication of a high
concentration.
23. Risk Assessments should be carried out and alternative safety arrangements should be put in place BEFORE
beginning any servicing or maintenance.
