IMPORTANT: SPECIAL CONDITIONS OF USE (X)
The enclosure’s coated surfaces are non-conducting and may
generate an ignition-capable level of electrostatic charge under
certain extreme conditions. The user shall ensure that the
equipment shall not be installed in a location where the external
conditions are conducive to the build-up of electrostatic charge
on non-conductive surfaces. Additionally, the equipment shall
only be cleaned with a damp cloth.
EQUIPMENT USE
1. Check the rating label to ensure the Floodlite is suitable
for the supply provided, ambient temperature present and the
environmental conditions.
2. 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.
3. Safe/Optimal Voltage Indicator (SOVI). The Wolf WF-250XL 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.
4. 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.
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 on the Wolf website:
www.wolfsafety.com. If a lamp is pulsing, it is recommended that
the lamp be switched off until it is operating at a correct voltage.
5. 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.
6. All Floodlites have terminal blocks suitable for incoming
cables for up to 4mm² conductor capacity.
7. 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.
8. 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 IP66/67 rating as marked
on the label.
9. Floodlites, cable and accessories 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.
