Introduction
The High Bay lights are designed for illumination of
industrial locations and use the latest in solid state
lighting technology for long life, low maintenance,
and high efficiency.
The unique optical design focuses light downward
to where it is needed, giving improved efficiency
over a conventional HID luminaire.
Conformity with Standards
This equipment conforms to the standards specified
in the Declaration of Conformity. It has been
designed, manufactured and
accordance with:
BS EN 9001.
ATEX Directive 2014/34/EU:
protective systems intended for use in potentially
explosive atmospheres.
EMC Directive 2014/30/EU: For electromagnetic
compatibility.

potentially explosive atmosphere in Zones 1, 21 and
2, 22 to the requirements of ATEX Directive
2014/34/EU. The product can be used inside or
outside to illuminate areas with a potentially
explosive atmosphere.
General Mounting Information
For maximum long term reliability and light output, the
light must be installed in free air. The High Bay
luminaire design incorporates an over-temperature
control circuit that reduces input power should internal

Recommended mounting height: 6-12m [20-40ft]
Stirrup Mounting Information
The 'Stirrup Bracket' is fixed into place using 2 bolts
and the threaded holes on the side of the luminaire.
When secured into the desired position the 2 bolts
should be tightened to 8.0 – 10.0Nm [6 – 8ft.lbs].
For 25K (HLA) models:
M8 bolts: 19Nm
M6 bolts: 7Nm

Note: Electrical installation of the extension should
be carried out by a qualified electrician.
For connecting the coloured fitted power cable
conductors is as follows:
- Brown wire connects to Live.
- Blue wire connects to Neutral.
- Green/Yellow wire connects to Safety Ground
(Earth).
For connecting the numbered fitted power cable
conductors is as follows:
- Wire 1 connects to Live.
- Wire 2 connects to Neutral.
- Wire 3 connects to Safety Ground (Earth).
WARNING: Do not remove or tamper with the certified
cable gland. The Ex 'd' rated gland has been
supplied and installed to the luminaire in accordance
with the manufacturer's instructions. Tampering with
this cable gland may compromise the IP66 rating and
result in flame propagation into the atmosphere.
Electrical Installation of Junction Box
The cable glands used with this luminaire must be
certified to the Ex 'e' requirements. The cable used
must be suitable for the site application and/or the
site requirements.
When assembling the cable entries for the mains
tested in
connection, always observe the manufacturer's
specifications for the glands used. Unused cable
entries must be closed and sealed by a certified
Equipment and
blanking plug. The cable entries should be securely
tightened to ensure that the minimum protection
rating is achieved. The cable entry should be rated
to minimum of IP66 to maintain the protection level
of the luminaire.
NOTE: This fixture is supplied with one dust cap and
one certified blanking plug.

gland manufacturer's data for torque settings.
The push terminal block (WAGO 862 series)* is
suitable for multi-stranded and single core cables
up to a maximum of 4mm2, strip length 10mm. Push
down at the 'cross point', insert correct cable and
release, ensuring the cable has been securely
retained.
The screw terminal block (Weidmüller MK 6/2/E)* is
suitable for multi-stranded and single core cables
up to a maximum of 6mm2, strip length 9mm.
Unscrew retaining tab, insert wire and tighten the
screw to 1.2-2 Nm, ensuring the cable has been
securely retained.
Loop Through Electrical Connections (for push
terminal block only)
Connect incoming cable as above then connect
the outgoing cable to the associated adjoining
connection to pass to the next luminaire.
NOTE: Only one cable to be used on each terminal

Chemical Compatibility Guide
The chemical compatibility data referenced in this
manual was supplied by
manufacturers and is intended as a general guide.
The data represents the basic material properties
and does not necessarily
performance of the final
manufacturing process and design variations for
each final product. Chemical compatibility is highly
dependent on concentration,
humidity, and other environmental conditions and
therefore the customer assumes responsibility for
evaluation of gaseous or direct contact chemical
compatibility at their site
installation.
