DISPOSAL OF WASTE MATERIAL
Disposal of packaging, LinkEx LED products, old LED panels
and drivers should be carried out in accordance with national
regulations, (WEEE).
The Wolf Safety Lamp Co. Ltd has a policy of continuous product
improvement. Changes in design details may be made without
prior notice. Prices and design are subject to alteration without
notice. All products sold are subject to our conditions of sale.
A copy of these instructions with any relevant revisions can be
found at www.wolfsafety.com.
CHANGING LED DRIVERS
Unscrew the internal & external wiring terminations from the
six & two way terminal blocks and remove the driver retention
bracket by unscrewing the two bolts. To reassemble follow the
above points in reverse order. For wiring and termination details,
see Fig. 1-6. Specified torque settings must be followed.
CHANGING GLASS LENS
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. See Fig. 14. Specified torque settings must be
followed.
FAULT FINDING
If a WF-250XL 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 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.
Risk of Shock
CHANGING LED PANELS
The LED panel can be removed by unscrewing four socket head
screws 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 Fig. 7. For wiring and termination
details, see Fig. 1-6. Specified torque settings must be followed.
CHANGING CABLE OR SOCKET
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. For wiring and termination details, see Fig. 1-6.
Specified torque settings must be followed.
If any change is made to cable, glands, plugs or sockets the
manufacturers instructions should be adhehered to, ensuring
the seal between the item and the cable is reliable.
Please note sockets and plugs have no IP rating unless
connected or sockets have covers closed.
FRONT COVER
Remove the front cover by unscrewing the four socket head
retaining bolts. Release the Earth connecting wire by releasing
the locking spade connnection in the floodlite by depressing the
tab on the connector and pulling away. See fig. 8.
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. Ensure
correct torque settings are followed, as specified in Fig. 7.
*The Certificate label and serial number are fitted to the front
cover, therefore do not interchange the front covers with other
WF-250XL Floodlites. See internal body label for serial number
reference.

MAINTENANCE
1.
IMPORTANT.
Any maintenance work should be carried out in
the safe area by suitably qualified and experienced technicians
only.
2. Isolate the Floodlite from the mains supply and allow to cool
before carrying out any maintenance work.
3.
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.
4. 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.
