Overhaul (Refer EN / IEC 60079-19)
Components to be incorporated into or used as replacement parts of the equipment shall be fitted by suitably
trained personnel and other than the fuse are to be purchased from the manufacturer as to ensure that
certification is not invalidated. The certification of this equipment relies upon the following materials used in its
construction: Glass re-enforced polyester body, polycarbonate diffuser, stainless steel clips and EPDM rubber
gasket.
The unit is largely made of materials that are very corrosion resistant. This allows the unit to be completely
stripped, cleaned and then re-built with new electrical parts as required. The internal wiring is 0.8mm² solid core,
HTPVC insulated. All the spares required are available. Please state the model identification string e.g.
ST3N/03L/LE.
The seal is between the polycarbonate diffuser and the base. The diffuser is retained by stainless steel clips. If the
sealing gasket has deteriorated by softening or permanent set, a new sealing gasket should be fitted, which can
be obtained from the manufacturer. To fit this, care is needed, the old gasket should be removed and remaining
adhesive scraped off. The gasket is fixed in place to the body with a small amount of silicone RTV.
It is the end users responsibility to ensure the materials of construction and the product certification as detailed on
the product label is suitable for intended installation location.

Fuse Ratings
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. Where MCB's are used,
the type with the higher short time tripping current ratio used for motor starting and lighting should be specified.
The inrush current can be calculated where circuit conditions are known. The inrush currents can be obtained
from the manufacturer.
The fuse ratings for LED strips in circuits need to take account of the Driver within the construction of the
Luminaire. All calculations must satisfy wiring regulations.
Note: Line currents for 230V, 50Hz are as indicated in Table B
.

Disposal of Material
Any disposal must satisfy the requirements of the WEEE directive [2012/19/EU] and therefore must not be treated
as commercial waste. The unit is made from combustible materials; the control gear contains plastic parts and
electronic components. All electrical components and the body parts may give off noxious fumes if incinerated.
Take care to render these fumes harmless or avoid inhalation. Any local regulations concerning disposal must be
complied with.
6.1
LED’s
LED’s in modest quantities are not "special waste". They should be broken in a container to avoid possible injury
from fragmentation. Avoid inhaling dust. This applies to the UK; there may be other regulations on disposal
operating in other countries.
Important:
Do not incinerate LED’s.
To comply with the Waste Electrical and Electronic Equipment directive 2012/19/EU 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.
