6 PRECAUTIONS
•Ensure that all covers on Exd housings and their fixing devices are properly secured in compliance with
statutory Exd regulations before switching on the input supply.
•Never remove the cover of an Exd housing whilst the input supply is connected. Isolate elsewhere
before removing the cover in accordance with statutory regulations.
•The housing of all power supplies must be securely earthed in compliance with statutory regulations.
•Carry out a current consumption audit to ensure that the maximum current loading of the power
supply is not exceeded.
•Ensure that the installation of the power supply, particularly with regard to the
connecting cables, complies with the certification parameters (section 7).
•Exd housings must be inspected and maintained regularly in accordance with statutory regulations.
•Use only the correct Trolex replacement fuses (section 7).
Do not substitute any form of equivalent or linking device.
•The TX6630 Series Exi Power Supply must be mounted in an approved Exd housing when located in a
hazardous area.
•All cables entering the Exd housing must be terminated with suitable Exd certified cable glands.
•The cabling between the Power Supply and other approved intrinsically safe devices must comply with
the cable parameters specified in the appropriate Ex certification of the device.
•Never connect two power supplies in parallel, or employ external circuitry that results in two Intrinsically
Safe Power Supplies circulating in one system. This will contravene the limits of Intrinsic Safety.
•Where an Intrinsically Safe Power Supply is fitted with auxiliary
Intrinsically Safe isolating relays, all the relay coils are powered
from a common Intrinsically Safe source.
•If an ac input fuse is ruptured at any time, it can be replaced. It is recommended however, that a full
investigation is carried out to try to establish the cause of the failure as this could indicate potentially
dangerous external conditions.
•It is good practice to check the condition of the mating flame path surfaces on the Exd chamber
cover whenever it is removed.
•Five x M25 threaded cable entries are provided on the underside of the Exd chamber for connecting
the incoming Power Supply and for connections to relay contacts if these are fitted.
Approved Cable Glands:
Hawke: 650 series Compound Filled M25 Thread
Hawke: 650 series Compound Filled M20 Thread (when used with a M25/M20 reducer).
Approved Thread Reducers:
Hawke: 476/R, M25/M20 Thread
•All unused cable entries MUST be blanked off with an APPROVED STOPPING PLUG.
Approved Stopping Plugs:
Hawke: 475, M25 Thread
•The requirements of the Exd certification of the TX6620 Series Intrinsically Safe Power Supply demand that
electrical isolation must be provided in the mains Power Supply feed. The isolation should be mounted
adjacent to the Power Supply.
•The metal housing of the Power Supply, should be earthed in compliance with local regulations.
•Ensure that the mating faces of the Exd chamber cover are clean and free from inclusions before the
cover is replaced. It is permissible to use copper grease on the mating faces to protect against
corrosion and moisture ingress.

If the apparatus is to be installed within a potentially explosive atmosphere, an additional
alternative type of protection, as listed in EN 50014:1997 + amendments 1 & 2 must be
provided - such as an appropriately certified flameproof enclosure.
If the apparatus is installed outside the potentially explosive atmosphere, it must be done so
in an earthed metal enclosure providing a degree of protection of not less than IP20 as defined
in EN 60529:1992.

6. Se è probabile che l’apparecchio venga a
contatto con sostanze aggressive, è compito
dell’utente prendere precauzioni idonee a
impedire che ne sia attaccato, garantendo
così che il tipo di protezione non venga
compromesso.
Sostanze aggressive sono, ad esempio, liquidi o gas
acidi che possono attaccare i metalli, o solventi che
possono colpire i materiali polimerici.
Precauzioni idonee sono, ad esempio, controlli
regolari che fanno parte di ispezioni ordinarie, o

Many of our products are often used to
monitor the quality of environmental
conditions consequently Trolex is also
particularly aware of the need to protect
human health and the environment in
which we live.
The Company has instituted a radical environment
protection policy to ensure that all aspects of our
manufacturing programme have the minimum
possible detrimental
impact on the environment. This covers all stages
beginning with sustainable product design
supported by careful selection of the materials
used in their production, through to managed
recovery and disposal at the end of the useful life
of a product.
This policy also incorporates the principles of the
Waste Electrical and Electronics Equipment (WEEE)
directive, and the associated Restriction of Hazardous
Substances (RoHS) directive, to be implemented in
EU countries.
Progress is already well advanced on the
introduction of a completely new range of
products that maximise the central principle of
sustainable design with the intention of reducing
the end-of-life cost to the end user.
All Trolex products are manufactured to exacting
standards in accordance with our stringent quality
control ethos. Having chosen to use one of our
products will, in itself, guarantee extended
durability and a long operating life, endorsed by
our commitment
to recycling and recovery.
- All packaging materials are carefully selected to be
bio-degradable or re-cycleable where possible.
- All plastic materials are identified for recycling
purposes and re-cycled materials are used where
it is possible to do so.
PROTECTING THE ENVIRONMENT
- Printing paper and material are sourced
from suppliers that have a declared
environmental management system.
- Product design centred around high
quality and long term durability.
- Modular architecture both in
construction and software design suitable
for future upgrades and adaptability to
alternative duty.
- Ease of product disassembly, minimisation
of fixing devices, and clear separation of
functional parts to benefit re-use and re-
cycling.
- Control and monitoring of suppliers of
components and sub-assemblies.
- Deal only with suppliers that have a
defined commitment to environmental
monitoring principles.
- Control the use of restricted substances
within the design process. Deal only with
suppliers that have a defined
commitment to the control of restricted
substances.
- Provide an efficient high speed service
within Trolex for repair, refurbishing and
conversion of products for alternative duty.
- Provision of an end-of-life product
Take-back service for recovery, re-use,
and recycling of electrical and electronic
components. Retain the packaging of a
new product and re-use it to return the
device to us at the end of its working
life. Trolex will guarantee to recover all
materials and components, where
practicable and arrange for them to be
re-cycled in an appropriate and in
a safe manner.
