1.0 Introduction – VL71 nR FLOODLIGHT.
The VL71 Floodlight is designed for all round lighting applications. It is suitable for use with tubular discharge lamps and
single ended tungsten halogen lamps. A gear box is used with the low voltage range of 400w HID versions.
The floodlight is restricted in its mounting position. The beam of the floodlight may be aimed at any angle but the control gear
must always be mounted on or below the axis of rotation of the floodlight.
The floodlight is designed to be safe in normal operation.
The floodlight should not be used in conditions where there are environmental, vibration or shock conditions above the normal
for fixed installations.
The gaskets should not be exposed to hydrocarbons in liquid or high concentration vapour states.
The floodlight is suitable for applications where category 3 apparatus is used. The application is for ignitable gas and dust
atmospheres. The floodlight is not suitable for portable applications.
Note : Lamp ranges and temperature ratings are outlined in TABLE 0.
2.0 Storage
Luminaires and control gear boxes are to be stored in cool dry conditions preventing ingress of moisture and condensation.
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 (IECEx) EN 60079-14 or the local hazardous area
code of practice, whichever is appropriate.
In the UK the requirements of the 'Health and Safety at Work Act' must be met.

IOM – VL71 FLOODLIGHT
VL71 IOM IECEx ATEX Issue 02 May 08 3
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 floodlights are Class 1 and should be effectively earthed.
The luminaires are quite heavy and suitable means of handling on installation must be provided.
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 EN 61241-14 for additional details of selection, installation and maintenance.
3.1.2 Hybrid Mixtures – Gas plus Dust.
Where Hybrid mixtures exist as defined in EN 1127 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 (IECEx) EN 61241-1, (IECEx) EN 61241-0 practice A.
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
A cross head screwdriver blade to open hinged cover.
3mm and 5mm flat blade screwdriver.
Suitable spanners for installing cable glands.
Pliers, knife, wire strippers/cutters.
3.3 Electrical Supplies
The supply voltage and frequency should be specified when ordering. A maximum voltage variation of +6%/-6% on the
nominal is expected. (The safety limit for T rating is +10%). Luminaires should not be operated continuously at more than
+6%/-10% of the rated supply voltage of the control gear or tapping. The user must determine the actual underlying site
supply and purchase or adjust accordingly. Care must be taken in connecting to the nominal 230V UK public supply.In
most cases, the luminaire has multi-tapped control gear which can be set to a range of voltages on 50 or 60Hz cycles. The
tappings are shown on the control gear and the limits are shown on the rating plate. If the equipment is located in high or low
voltage sections of the system, an appropriate voltage tap should be selected, but care must be taken to log or mark the
equipment so that the tapping is re-set if the equipment is re-located. If in doubt, tappings should be set on the high side,
10V max. drop is desirable for HPS. The light output will be reduced. The HPS circuits use S.I.P ignitors and the circuit
diagram will indicate the choke connections. Where MBI/Metal Halide lamps are used, the tapping must be set accurately for
best performance. Where shore or construction site supplies are used, different to the service supplies, tappings should be
re-set. If not, advice on the effect of these temporary supplies should be sought from the Technical Department. Where
adverse system conditions occur, luminaires can be supplied without PFC. The circuit current will then be the lamp current.
The circuit power does not change. Tungsten Halogen lamps must be selected for the supply voltage. Running at over the
rated supply voltage will reduce life and at greater than +10% will compromise the T rating.

3.4 Lamps
The lamps used in this range are of a standardised type, and there is no preference between makes, or in the case of HPS
colour. Due to the need to control photometric performance and certification conditions, and avoid incorrect lamps being
fitted, the type of lamp and size is specified on the rating plate. If mixed installations are used, care must be taken to ensure
that the correct lamp is fitted on installation and replacement.
HPS and MBI lamps should be replaced shortly after they do not light. One indication of the end of life for HPS lamps is
'cycling' where the lamp goes out then re-ignites after a minute or so interval. If discharge luminaires are burned continuously
they should be switched off occasionally, to allow old lamps to fail to re-ignite rather than possibly become diodes with
detrimental effects on control gear. The above information is current at the time of publication. The development of lamps
and control gear is ongoing and detailed advice on lamp performance can be obtained from the Technical Department or the
lamp supplier. HPS and MBI circuits should not be energised without a lamp fitted. HPS lamps without an internal
ignitor should be used. The current HPS control gear is incompatible with internal ignitor lamps.
3.5 Mounting
Floodlights 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
Cable glands and sealing plugs when installed must maintain the properties of the restricted breathing enclosure.
Rubber sealing washers and steel compression washers are provided with the unit.
The installer and user take responsibility for the selection of cables, cable glands and seals.
The product is certified for ATEX and to comply with the certification for installation and use within the EU, cable glands and
sealing plugs must have ATEX component approval.
For installation outside the EU, suitable cable glands in accordance with (IECEx) EN 60079-0 will meet the technical
requirements.
The cable and gland assembly when installed must maintain the IP66/67 rating of the floodlight.
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 20 x the cable OD in mm for
non-armoured cable and 80 x 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. A Hawke 501/453/RAC would be suitable for the above.
3.6.2 Cable
At maximum rated ambient temperature refer to rating table for minimum cable temperature rating. The luminaire is also
rated with the temperature rise at the cable entry. This allows the user to adjust the cable spec. for an actual T amb lower
than that for which the luminaire is certified. The standard looping conductor size is 6mm².
Internal and external earth points are provided.
Standard 300/500V rated cable is suitable. The cable make-up must be suitable to ensure the maintaining of the restricted
breathing enclosure when the cable gland assembly is fitted.
The selection of cable size will be suitable for the fuse rating. Some guidance on this is given below. When MCB's are used,
the type with the higher inrush current resistance, as used for motor starting and lighting, should be specified.
3.6.3 Cable Connection
The cable connections are made by removing the front cover. Before removing front cover check that the support chain is
sound. The cover is released by undoing the six toggle clamps, using a screwdriver or suitable metal rod. The reflector is

IOM – VL71 FLOODLIGHT
VL71 IOM IECEx ATEX Issue 02 May 08 5
removed by releasing four screws. The baffle plate is removed by undoing 2 x M5 nuts at the base. Reselect the voltage
tapping if necessary. No more than one single or multiple strand lead shall be connected into either side of any terminal,
unless multiple conductors have been joined in a suitable manner, e.g. two conductors into a single insulated crimped
bootlace ferrule. Leads connected to the terminals shall be insulated for the appropriate voltage and this insulation shall
extend to within 1mm of the metal of the terminal throat. All terminal screws, used and unused, shall be tightened down to
between 1.2 Nm and 2 Nm. The cover is replaced and the toggle clamps snapped back over.
3.7 Fitting Lamps
Make sure the correct lamp is selected, access for fitting lamps is gained through the lampglass cover, as above. The lamp
should be firmly screwed into place.
3.8 Inspection and Maintenance
Visual inspection should be carried out at a minimum of 12 monthly intervals and more frequently if conditions are severe,
refer to (IECEx) EN 60079-17. The time between lamp changes could be very infrequent and this is too long a period without
inspection.
3.8.1 Routine Examination
The equipment must be de-energised before opening and note taken of the rated opening delay periods alternatively the
nameplate may read ‘do not open when an explosive gas atmosphere is present’. Individual organisations will have their own
procedures. What follows are guidelines based on (IECEx) EN 60079-17 and on our experience:
1 Ensure the lamp is lit when energised and that the lampglass is not damaged.
2 When de-energised and left to cool there should be no significant sign of internal moisture. If there are signs of water
ingress, the luminaire should be opened up, dried out, and any likely ingress points eliminated by re-gasketting, re-
greasing or other replacement.
3 Check the cable gland for tightness and tighten if necessary.
4 Check any external earthing.
5 Examine the glass for any signs of damage. Clean glass.
6 When relamping, check that the cover gasket has not softened or become excessively deformed, if in doubt replace
(see section 4.0 ).
Important : Where spares are needed, these must be replaced with manufacturers parts.
No modifications should be made without the knowledge and approval of the
manufacturer.
3.9 Electrical Fault Finding and Replacement
The supply must be isolated before opening the luminaire.
Control gear will not normally go open circuit unless it has overheated first and the signs of this are obvious, being severe
discoloration of the paint on the gear and cracks in any exposed insulation. Similarly, a bad contact at the lamp cap will
usually result in signs of overheating. Any fault finding must be done by a competent electrician and, if carried out with the
luminaire in place, under a permit to work.
With HPS and MBI lamps the ignitor can become faulty. If the lamp is fitted, the choke has continuity and the connections are
good and correct, they should produce an 'attempt to start' effect and a buzzing sound from the ignitor. It will be unusual to
have no other parts available to perform a substitution fault finding routine and this is the normal procedure. Before re-
assembling, all connections should be checked and any damaged cable replaced. The ignition connection to the lampholder
is sleeved with a high temperature silicone sleeve and this must be kept in place.
3.9.1 Thermal Protector
Thermal protectors are included. If the lamp goes on and off over a timescale of several minutes, this could be the thermal
protector operating. The causes are defective lamps/diode effects, gross over voltage or the choke beginning to fail and this
should be investigated directly. Also see section 3.4.

VL71 IOM IECEx ATEX Issue 02 May 08 6
4.0 Overhaul
The unit is largely made of materials which are very corrosion resistant. This allows the unit to be completely stripped,
cleaned then re-built with new electrical components as required. All spares required are available. Please state the model
number, lamp and reflector details. The seal at the cover is between the glass and the body. The glass is retained in the
cover frame by silicone R.T.V. adhesive. If the cover gasket has deteriorated a new cover assembly should be fitted, which
can be obtained from Victor.
4.1 Fuse Ratings
The fuse ratings for HID lamp circuits need to take account of three components of circuit current. Current inrush to PFC
capacitors which can be up to 25 x the rated capacitor current, and last 1-2 milliseconds. Lamp starting current including
steady capacitor current which together may decline from up to 200% of normal at 10 seconds after switch-on to normal after
4 minutes; rectification effects caused by asymmetrical cathode heating for a few seconds after starting, this effect is random
and very variable.
With the availability of MCB's with a wide range of characteristics, the individual engineer can make a better judgement of
what is required. Use MCB's suitable for inrush currents to reduce ratings. The normal capacitor current, will probably be the
determining factor, 0.076A per μF at 240V, 50Hz (adjust for other volts by multiplication, x 6/5 for 60Hz). For HBC fuses use
1.5 x normal capacitor current. For GLS inrush use 6 x rated current. All calculations must satisfy wiring regulations.
Note : S tarting and running currents for 240V, 50Hz are as indicated in TABLE 1.
A conventional matrix for HBC fuses is shown in TABLE 2.
5.0 Disposal of Material
Any disposal must satisfy the requirements of the WEEE directive [2002/96/EC] and therefore must not be treated as
commercial waste. The unit is mostly made from incombustible materials. The control gear contains plastic, polyester resin
and electronic components. All electrical components may give off noxious fumes if incinerated.
5.1 Lamps
Incandescent lamps and discharge lamps in modest quantities are not "special waste". The outer envelope should be broken
in a container to avoid possible injury by fragmentation.
This applies to the UK, there may be other regulations on disposal operating in other countries.
Important : Do not incinerate lamps.
5.2
To comply with the Waste Electrical and Electronic Equipment directive 2002/96/EC the apparatus cannot be
classified as commercial waste and as such must be disposed of or recycled in such a manner as to reduce the
environmental impact.
