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.
