Please Retain – Read Before Use
EC Declaration of Conformity
The Wolf WF-300 LED Floodlite meets all relevant
provisions of the 94/9/EC (ATEX Equipment) Directive
by virtue of the issued EC Type Examination
Certificate, demonstrating compliance with all relevant
Harmonised Standards and Essential Health and
Safety Requirements.
The Wolf WF-300 LED Floodlite is a high performance
lightweight portable floodlight. Constructed in marine
grade aluminium, with a polycarbonate lens: the end
user must check that these materials are suitable for
the atmosphere the Floodlite will be used in. The
Floodlite can be used in Zone 1 and Zone 2 potentially
explosive gas, vapour, mist and dust atmospheres
where the surface temperature / temperature class
and gas group permit.
The incoming mains cable should not exceed a
temperature rise of 61oC above the ambient
conditions; select suitable cable and cable gland.

IMPORTANT
Read these instructions carefully before commencing
to use the Floodlite and retain for future use.
•Check the rating label to ensure the Floodlite is
suitable for the supply provided, ambient
temperature present and IP rating.
•ATEX certification includes assessment of product
safety at ±10% of rated voltage, running lamps
outside of this voltage tolerance will therefore
invalidate the ATEX approval and the product
warranty, may result in a dangerous condition, and
could cause the product to fail prematurely.
•If the Floodlite is to be used in areas of high
vibration, please consult with Wolf Safety.
•ELECTROSTATIC CHARGING HAZARD Clean
lens with damp cloth.
•The Floodlite consists of an Ex mb LED chamber
and an Ex emb terminal chamber.
•All Floodlites have terminal blocks suitable for up
to 4mm2live, neutral and earth.
•ATEX approved cable glands must be used and
be suitable for the type of cable used. Any unused
cable entries should be blanked off with a suitable
ATEX approved stopper plug to maintain a
minimum IP66/67 rating as marked on the label.
•This product is Class1 equipment and must be
earthed. Floodlites are supplied as standard with 3
core earthed supply cables. Where the user
specifically requires a 24 volt SELV Floodlite with
2 core cable (+ve and -ve) / a 2 pole plug, the
Floodlite must be used with a separate connection
to earth via the external earth grounding point.
•The Floodlite lens is moulded in Polycarbonate,
the end user must ensure that this is suitable for
the atmosphere the Floodlite will be used in.
•Do not connect 24 volt lamps to a centre
tapped earth transformer (CTE), permanent
damage to the product is likely to occur.
When user is ≤0.35m from the WF-300:
Risk Group 2.
Caution: possible hazardous optical radiation
emitted from this product DO NOT stare at the
operating lamp. May be harmful to the eye.
Special conditions for safe use (denoted by X
after the certificate number)
•Always use the lamp in the bridle provided.
•Except for internal wiring, not 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 boot lace ferrule.

•Leads connected to the terminals shall be
insulated for the appropriate voltage and this
insulation shall extend to within 1 mm of the
metal of the terminal throat.
•When terminals in accordance with certificate
IECEx SIR 05.0035U are used, all terminal
screws, used and unused, shall be tightened
down to between 0.5 Nm and 0.7 Nm.
•When terminals in accordance with certificate
IECEx SIR 05.0037U are used, all terminal
screws, used and unused, shall be tightened
down to between 1.2 Nm and 2 Nm.
•When terminals in accordance with
certificates IECEx SIR 05.0035U and IECEx
SIR 05.0037U are used, they shall only be
installed and wired with cable within a
temperature range of -10°C to 80°C.
•When cross-connecting combs are used on
terminals to certificates IECEx SIR 05.0035U
and IECEx SIR 05.0037U, the relevant
conditions of certification associated with
those certificates shall be applied.
•Cable entry holes shall be fitted with either an
appropriately certified cable gland or
appropriately certified blanking element.
These shall provide and maintain a minimum
enclosure ingress protection of IP66 or IP67
as appropriate.
•The LED assembly must be replaced
following the failure of a maximum of 8
individual LED’s.
•Internal fuse replacement must be the correct
fuse value and be capable of withstanding a
short circuit current of 1500A.
•User must ensure that when used, the
protective film must remain fixed in place at all
times when the equipment is being moved.
•If the Floodlite head is not situated within the
protective frame/stand ensure the unit is de-
energised before moving.
MAINTENANCE
1. Isolate the Floodlite from the mains supply
and allow to cool before carrying out any
maintenance work.
2. It is essential that all Floodlites are maintained
in accordance with the requirements of
EN60079-17.
3. The cable should be inspected before each
use. Regular close inspections must be
carried out to ensure the cable is not
damaged in any way. Particular attention
should be paid to gland and socket entries.
4. IMPORTANT. No modifications are permitted
to the Floodlites, all spare parts must be
purchased from the manufacturer,
unauthorized modifications or spare parts will
invalidate certification.
ELECTRICAL DATA
Total circuit watts 60W, power factor correction
better the 0.95. Voltage range 100V to
254V +/-10% 50/60Hz or 24V +/-10% AC/DC –
see rating label. PAT testing, maximum insulation
testing may be carried out at voltages less than or
equal to 500V DC, if the Live and Neutral cables
are shorted together and the voltage applied
between earth and this connection.
CHANGING LED ASSEMBLIES
Isolate the Floodlite, remove the lid assembly by
releasing the 4 socket head bolts that are
retained in the polycarbonate cover, the inner
LED assembly can now be removed by releasing
the 4 socket head screws, the casting with the
encapsulated LED’s can now be discarded.
Fitting a new LED assembly is a reversal of the
above procedure.
DISPOSAL OF WASTE MATERIAL
Disposal of packaging, Floodlite and old LED
assemblies should be carried out in accordance
with national regulations.
