3.0 Installation and Safety
3.1 General
There is no health hazards associated with this product whilst in normal use. However, care should be exercised during the
following operations. Installation should be carried out in accordance with ABNT NBR IEC 60079-14 or the local
hazardous area code of practice, whichever is appropriate, and fitting of specified insulating material to be
adhered to where a specific fire resistance rating is required.
In the UK the requirements of the 'Health and Safety at Work Act' must be met.
Handling and electrical work associated with this product to be in accordance with the 'Manual Handling Operations
Regulations' and 'Electricity at Work Regulations, 1989'. Your attention is drawn to the paragraphs
(i) 'Electrical Supplies',
(ii) 'Electrical Fault Finding and Replacement' and
(iii) 'Inspection and Maintenance'. The luminaires are Class 1 and should be effectively earthed.
The luminaires are quite heavy and suitable means of handling on installation must be provided.
Maximum Insulation Resistance Test 500V dc.
Guards and External Reflector can be supplied with or fitted retrospectively, the guard is to protect glass if there is a higher
than normal risk of mechanical damage. The guard and External Reflector cannot be fitted together.
This LED Floodlight luminaire has passed thermal shock testing during certification, it is still advisable to mount the Floodlight
in locations to reduce the possibility of thermal shock.
Certification details on the rating plate must be verified against the application requirements before installation.
The information in this leaflet is correct at the time of publication. The company reserves the right to make specification
changes as required.
3.1.1 Use in Combustible Dust Atmospheres
Where the equipment is used in ignitable dust atmospheres reference must be made to the selection and installation
standards in order that the equipment is used correctly. In particular this applies to the de-rating of surface temperature for
use where dust clouds may be present. Dust layers should not be allowed to accumulate on the fitting surface and good
housekeeping is required for safe operation. Dust in layers has the potential to form ignitable clouds and to burn at lower
temperatures. Refer to ABNT NBR IEC 60079-10 & ABNT NBR IEC 60079-14 for additional details of selection and
installation.
3.1.2 Hybrid Mixtures – Gas plus Dust.
Where Hybrid mixtures exist as defined in EN1127 as a potentially explosive atmosphere, consideration should be given to
verifying that the maximum surface temperature of the luminaire is below the ignition temperature of the hybrid mixture.
3.1.3 Floodlight Orientation in the presence of combustible dust.
The luminaire was tested in accordance with ABNT NBR IEC 60079-31. As the build up of the dust layer can never be
guaranteed not to occur, the luminaire must not be mounted in an orientation where the dust could lie on the glass. The
temperature on the glass is the hottest point on the luminaire and any obstruction of the radiation from the luminaire would
cause the surface temperature to increase.
3.2 Tools
6mm A/F socket keys
4mm flat blade screwdriver
Suitable spanners for installing cable glands
Pliers, knife, wire strippers/cutters

3.3 Electrical Supplies
A maximum voltage variation of +6%/-6% on the nominal is expected. The safety limit for T rating is +10%.
3.4 Light Source
The luminaire is fitted with LEDS that can last 80,000 hours depending on ambient temperatures. Therefore depending on
the functionality of the fitting replacement of LED’s will be rare /unnecessary. If the LED assembly needs replaced refer to 4.2
LED Replacement.
3.5 Mounting
Luminaires should be installed where access for maintenance is practical and in accordance with any lighting design
information provided for the installation. This will usually consist of aiming points and aiming angles. Mounting arrangements
should be secured with lock washers or self-locking nuts and bolts.
3.6 Cabling and Cable Glands
3.6.1 Cable Glands
The installer and user must take responsibility for the selection of cables, cable glands and seals.
The product is certified for INMETRO and to comply with the certification for installation cable glands and sealing plugs must
be certified “Geração E”.
Cable glands for entry into Ex e enclosures when fitted with any gland to body sealing method and the supply cable must
reliably maintain the IP rating of the enclosure IP66.
The cable gland must withstand an impact value of 7Nm where the risk of mechanical damage is high or 4Nm where the risk
of mechanical damage is low.
Sealing plugs must be similarly rated and a tool must be used for their removal. Where the cable is not reliably clamped
externally to the apparatus, the cable gland must clamp the cable against a pull in Newtons of 20x the cable OD in mm for
non-armoured cable and 80x the cable OD for armoured cable. Where brass cable glands are used in a corrosive
environment cadmium or nickel plating should be used. Two tapped cable entries are provided, one with a plug and seal
suitable for permanent use, the other has a travelling plug. M20 x 1.5 entries are standard, other sizes are available on
request up to M25 x 1.5p.
3.6.2 Cable
The temperature ratings of the entries at 55ºC ambient requires cable rated at 90ºC. Cables rated at 35ºC above ambient
are suitable for use at lower ambient installations.
3.6.3 Cable Connection
The cable connections are made by removing the terminal chamber cover. The retaining screws are captive and should be
re-greased as required. The conductors should be bared back so that they make full contact in the terminals, but the bare
conductor should not be more than 1mm beyond the terminal. Unused terminal screws should be tightened. The core must
be identified by polarity and connected in accordance with the terminal markings. Before re-fitting the cover, a final check on
the correctness of connections should be made. Cover bolt torque 16 Nm.

4.0 Inspection and Maintenance
Individual organisations will have their own procedures for inspection and maintenance. What follows are guidelines based
on ABNT NBR IEC60079-17 and on our experience. Maintenance work and fault finding must be performed by competent
personnel under an appropriate permit to work and with the apparatus isolated. Frequency of maintenance will depend on
experience and the operating conditions.
Luminaire should not be opened when an explosive atmosphere is present.
Maximum Insulation Resistance Test 500V dc.
1 Check if any LED’s have failed (do not light).
2 The LED',s are mounted on three boards, if there is 3 or more LED's not working on one board the light output will have
dropped to a level where the LED board may need replaced. Refer to 4.2 LED Replacement.
3 Check the terminal chamber bolts for tightness.
4 Check the cable gland for tightness and re-tighten if necessary.
5 Check any external earthing.
6 Examine the lampglass for any signs of damage and for any signs of sealant damage, cracking or discoloration. If
thought necessary, the silicone weather seal can be re-sealed with a proprietary brand of clear RTV silicone, but only if
the underlying sealant is in good condition.
7 Check all cover bolts for tightness. Torque 16Nm
8 Check for signs of corrosion between the lampglass cover and the main housing. Evaluation of this will be a matter for
judgement gained by experience, as there may be little evidence on the outside. If there is any sign of corrosion,
remove the cover and wipe the flameproof paths with a clean cloth and non-metallic scraper. Examine the surfaces for
pitting; any pitted component should be replaced. A damaged or non-resilient gasket must be replaced (supplied by
Chalmit).
The cover should be re-fitted with all bolts fully tightened. Any replacement bolts must be identical to the original. All
are 18/8 stainless steel with a minimum of ISO262 Grade A4-70.
With this type of flameproof path all bolts must be in place and tight. The maximum gap for IIB + H2 in this case is
0.05mm. It would be unusual for any of our luminaires to have a gap exceeding 0.05mm when tried with a feeler
gauge. If 0.05mm is exceeded check that no foreign bodies or debris at the bottom of blank tapped holes are
keeping the surfaces apart and if not, a workshop overhaul should be carried out to bring the unit into new condition.
Even if there are no signs of external corrosion the front cover should be removed at a minimum of every 3 years and
the internal connections checked for tightness and any signs of overheating.
9 The terminal chamber should be opened periodically and checked for moisture and dirt ingress. The cable connections
should be checked for tightness. The gasket should be checked for cracks or lack of elasticity, and if necessary,
replaced. (It may well be practical to also replace the gasket on each occasion if this is at a 3-year interval). (supplied
by Chalmit).
10 If painting operations have taken place around the luminaire, ensure that coatings have not entered the flameproof path
or been deposited on the lampglass. If they have, dismantle and clean carefully.
11 Check that mountings are secure.
12 Cover the bolt heads with silicone grease to prevent corrosion and accumulation of dirt in the screw threads.
13 Clean the lampglass.
14 If there is suspicion that the luminaire has suffered mechanical damage, a stringent workshop check should be made.
Important: Where spares are needed, these must be replaced with manufacturer parts. No modifications should be made
without the knowledge and approval of the manufacturer.
4.1 Electrical Fault Finding and Replacement
Any fault finding must be done by a competent electrician with the luminaire isolated and if carried out with the luminaire in
place, under a permit to work. Fault finding is by substitution with known good components.

4.2 LED Replacement.
The need and frequency of replacing LED’s be dependent on the functionality of the fitting. If it is continually running at high
ambient temperatures it will affect the frequency of LED replacement. If it is necessary to replace the LED’s, the LED’s are
mounted on three separate boards that can be replaced individually. (The boards with LED's supplied by Chalmit ).
Removal of LED assembly is as follows:
1. Unscrew 5 off screws that secure the board to the casting.
2. Carefully lift the plate and disconnect push in connector.
Replacement of LED assembly is the reverse of the removal.
Replace Front cover and fully tighten all bolts.
5.0 Disposal of Material
The unit is mostly made from incombustible materials. The control gear contains electronic components and synthetic resin.
All these may give off noxious fumes if incinerated. Care must be taken to render these fumes harmless and avoid
inhalation. Any local regulations concerning disposal must be complied with. Any disposal must satisfy the requirements of
the WEEE directive [2012/19/EU] and therefore must not be treated as commercial waste.
