3.0 Installation and Safety
3.1 General
There are no health hazards associated with this product whilst in normal use. However, care should be
exercised during the following operations.
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 information in this leaflet is correct at the time of publication. The company reserves the right to make
specification changes as required.
The polycarbonate diffuser presents a potential source of ignition by
electrostatic electricity
. The diffuser
should only be cleaned using a damp cloth. The luminaire should not be mounted very near to any probable
location of fast-moving stream of dry air, steam etc. which could generate a propagating brush static discharge.
3.1.1 Use in Combustible Dust Atmospheres – Zone 22
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. 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 (IEC) 60079-10-2 & EN (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 Cleaning
The body of the luminaire may be cleaned with a mild solution of household detergent and water, after cleaning
the body should be washed and wiped with clean water. The diffuser should not be polished or wiped with a dry
cloth, as a risk of explosion due to electrostatic discharge may result. Cleaning of the diffuser with any chemical
or hydrocarbon solvent-based cleaner may result in severe damage.
3.1.4 Aggressive substances
If the equipment is likely to meet aggressive substances, then it is the responsibility of the user to take suitable
precautions that prevent it from being adversely affected, thus ensuring that the type of protection provided by
the equipment is not compromised.
Aggressive substances: e.g. acidic liquids or gases that may attack metals or solvents that may affect polymeric
materials.
Suitable precautions: e.g. regular checks as part of routine inspections or establishing from the material’s data
sheets that it is resistant to specific chemicals.
3.2 Tools
12mm, 5mm and 3mm flat blade screwdriver. Pozi number 2 screwdriver
Suitable spanners for installing cable glands. Pliers, knife, wire strippers/cutters.
3.3 Electrical Supplies and Control Gear
Luminaires fitted with electronic control gear are suitable for a rated supply of 230Vac 50-60Hz,
The safety limits are +10% of this, however, luminaires should not be operated continuously at more than +/-
10% of the rated supply voltage of the control gear
.
The supply would normally be expected to lie /-6% of
rated. The LED supply is regulated, therefore the light output over the range is substantially unchanged.
The driver can also utilise DC voltage 176-264Vdc.
Electronic gear has integrated power factor correction to >0.90.
Warning:
Luminaires are assessed and/or tested for EMC requirements. This is based on the disposition
of entry cables and, where appropriate, through wiring arrangements as supplied or specified.
