SPECIAL CONDITIONS OF USE (X CONDITION)
The Floodlite enclosure coated surfaces are non-conducting
and may generate an ignition-capable level of electrostatic
charge under certain extreme conditions. The equipment shall
not be installed in a location where the external conditions are
conductive to the build-up of electrostatic charge on these non-
conductive surfaces. Additionally, the equipment shall only be
cleaned with a damp cloth.
The Floodlite can be fitted with a protective cover (WF-462), when
fitted the maximum ambient temperature lowers from +55°C to
+40°C. Use only Wolf supplied accessories.
Equipment Use
Check the rating label to ensure the Floodlite is
suitable for the supply provided, ambient temperature present
and the environmental conditions.
• It is the user’s responsibility to ensure there is no potential
difference between the earth supply to a Floodlite unit
and the local earth in the work area. Where this is not
possible the equipment should be securely earth bonded to
metalwork in the immediate vicinity of where the Floodlite
is being used. A flexible cable is recommended (6mm2
minimum, no more than two metres long), connected to the
earth grounding point on the Floodlite enclosure. Floodlites
must be de-energised during connection or disconnection of
the local earth bond.
• Safe/Optimal Voltage Indicator (SOVI). The Wolf WF-300XL
LED Floodlite incorporates SOVI technology to highlight to
the user if the product is operating outside of the certified
maximum and recommended minimum voltage range.
• The diagram below represents the SOVI function,
it demonstrates that when the voltage is not within
the “Safe/Optimal Voltage” the light output will
change from a constant uninterupted beam to a pulse.

• The Floodlite is approved with a range of protective
consumable accessories that are designed to protect and
extend its maintained lifecycle. These accessories should be
replaced when damaged or the light output is obscured.
• When the polycarbonate Floodlite Lens Guard (WF-421) is
fitted to the Floodlite, the end user must ensure that this is
suitable for the atmosphere the Floodlite will be used in.
• Inspect seals. Silicone seals are used in the construction
of the lamp. Where conditions could include exposure to
chemicals that may react with silicone, seek further advice.
• If connecting a large number of Floodlites check
for SOVI indication on all the lamps in the string.
Guidance on lamp connection and extensions can
be found at www.wolfsafety.com
• This product is Class 1 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.
• All Floodlites have terminal blocks suitable for
incoming cables for up to 4mm² conductor capacity.
• Ex “e” certified Increased Safety terminal blocks
must have all terminals fully tightened down even
if a conductor is not fitted. On all terminal blocks,
tighten screws to 0.5-0.7Nm.
• ATEX/IECEx 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/IECEx approved
stopper plug to maintain a minimum IP67 rating and
temperature rating as marked on the label.
• Floodlites and cable should be inspected prior to each use
for visible signs of damage. Particular attention should be
paid to gland and socket entries. Damaged lamps should be
removed from the work area and repaired before being put
back in service.
• Plugs must be connected and fully engaged in the correct
socket to maintain the IP rating of the plug and socket.
WF-300XL LinkEx Floodlites and any connected power
distribution equipment, fitted with a socket, must have the
socket covers closed when not in use to maintain IP rating of
the socket housing.
TECHNICAL DATA
ELECTRICAL DATA
MAINTENANCE
• Only suitably qualified and experienced technicians are to
assemble/disassemble the Floodlite.
• Isolate the Floodlite from the mains supply and allow
to cool before carrying out any maintenance work.
• 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.
• Portable Appliance testing must be carried out to IEC,
EN standards to the correct rating i.e. 250V DC for
18-50V versions and 500V DC for 90-264VAC versions.
Live and neutral cables must be shorted together and the
voltage applied between earth and this connection.
FRONT COVER
Remove the front cover by unscrewing the four socket head
retaining bolts. Release the Earth connecting wire by releasing
the locking spade connection in the floodlite by depressing
the tab on the connector and pulling away. Perform repairs/
maintenance as necessary. To reassemble follow the above
points in reverse order. Take care not to trap/crush wires and
ensure the seal is in good condition.
*The Certificate label and serial number are fitted to the front
cover, therefore do not interchange the front covers with other
WF-300XL Floodlites. See internal body label for serial number
reference.
CHANGING CABLE OR SOCKET
See diagrams overleaf
Disconnect the input cable, release cable from input gland.
Check the gland seal is in good condition, fit the new part(s) and
re-assemble the product by following the stated procedure in
reverse order.
If any change is made to cable, glands, plugs or sockets the
manufacturers instructions should be adhered to, ensuring the
seal between the item and the cable is reliable.
CHANGING LED PANELS
See diagrams overleaf
Each LED panel can be removed by unscrewing four socket head
bolts and the wiring terminations. Discard the old panel and
replace with a new one by following the removal procedure in
reverse. A new thermal pad must be fitted on replacement under
the LED panel as shown in the exploded diagram.
CHANGING LED DRIVERS
See diagrams overleaf
Unscrew the internal & external wiring terminations from the
six & four way terminal blocks and remove the driver retention
bracket by unscrewing the two bolts. One or both drivers can be
replaced. To reassemble follow the above points in reverse order.
CHANGING GLASS LENS
See diagrams overleaf
Replace the glass by unscrewing the six socket head screws
securing the three retaining plates. Fit the new glass making
sure strip gasket material is fitted between the glass and each
retention plate.
FAULT FINDING
Risk of Shock
If a WF-300XL Floodlite fails to function, remove the product from
service into a non hazardous area. Remove the cover and apply
power to the Floodlite. Check the input voltage at the terminals is
present and is the correct rating for the Floodlite. If the voltage is
correct the check the output voltage to the LED panels, this should
be 19V DC+/-1V. If this voltage is not present then the driver is
faulty, if it is then the LED panel is faulty. Replace as necessary.
DISPOSAL OF WASTE MATERIAL
Disposal of packaging, redundant LinkEx LED products and parts
should be carried out in accordance with applicable regulations.
