IMPORTANT: SPECIAL CONDITIONS OF USE (X)

1. 

The user/installer shall ensure that, when the Luminaire is fitted with a previously 

certified plug that has associated special conditions for safe use, they shall take into 

account any restrictions or conditions for safe use that are applicable to these devices.

2. 

Linkable luminaires fitted with Marechal sockets are certified for low impact risk 

use only, do not expose to shocks greater than 4 joules.

EQUIPMENT USE

1. 

Read this document carefully before first use of the Wolf LinkEx™ LED Temporary 

Luminaire and retain for future reference.

2. 

Check the rating label to ensure the Wolf LinkEx™ LED Temporary Luminaire 

is suitable for the supply provided, ambient temperature present and the 

environmental conditions.

3.   In areas where processes that induce circulating currents in the earth system are 

being undertaken, such as electric welding, it is the user’s responsibility to ensure 

there is no potential difference between the supply earth and the earth local to the 

luminaire. If a potential difference exists there is a risk of arcing should the luminaires 

end cap fixings or metal gland come into contact with local metal work. In these 

situations, the luminaire should also be locally earth bonded with a flexible cable,  

no longer than 2 meters, with a conductor area of 6mm2 minimum. The luminaire 

must be de-energised during connection or disconnection of the local earth bond.  

An external Earth Bonding Stud is available in the spares list and can be retro 

fitted in place of one of the end cap retaining screws.

4. 

Safe Operating Voltage Indicator (SOVI). The Wolf LinkEx™ LED Temporary Luminaire 

incorporates SOVI technology to highlight to the user if the product is operating 

outside of the certified maximum  and recommended minimum voltage range.  

 

The LX-400SH../T4/. 110/230 versions operating over 264V AC will pulse dim  

the light. The luminaire must not be used over this voltage.

 

When operating below 90V AC** the dimmed light will pulse brighten.

 

**The light output reduces incrementally as the supply voltage falls below  

100V AC. The luminaire will shut down if the supply voltage continues to fall.

 

The LX-400SL../T4/. 24/48 versions operating over 50V AC/DC will pulse dim  

the light. The luminaire must not be used over this voltage. When operating below  

18V AC/DC*** the dimmed light will pulse brighten.

 

 

***The light output reduces incrementally as the input voltage falls below 19V  

AC/DC. The luminaire will shut down if the supply voltage continues to fall.

 

If connecting a large number of luminaires check for SOVI indication on all the 

lamps in the string. Guidance on lamp connection and extensions can be found at 

www.wolf-safety.co.uk

5. 

The Wolf LinkEx™ LED Temporary Luminaire enclosure is constructed from 

polycarbonate parts, check Ex area for potential contact to corrosive and/or 

aggressive substances.

6. 

The Wolf LinkEx™ LED Temporary Luminaire is class 1 earthed electrical 

equipment, using 3 core cable. 

7. 

Ex e terminal blocks must have all terminals fully tightened down even if a 

conductor is not fitted. On the six way terminal block, tighten screws to 0.6Nm, 

on the 4 way terminal block tighten to 1.8Nm.

8. 

ATEX/IECEx certified cable glands must be used and be suitable for the type of 

cable used. 

9. 

Ensure cable is rated for the ambient temperature the Wolf LinkEx™ LED Temporary 

Luminaire will be used in, standard SY cable is not rated for use below -5ºC.

10.  Inspect cable for damage at regular intervals. 

11.  Damaged equipment should be withdrawn and repaired as necessary before 

being put back in to service, in accordance with EN60079-17. 

12.  Luminaires must not be opened in Hazardous Areas.

13.  When the Wolf LinkEx™ LED Temporary Luminaire is used in temporary 

installations two mounting points must be used, see Wolf bracket fixing kits and 

associated accessories. 

14.  The Wolf LinkEx™ LED Temporary Luminaire can be carried whilst energised/illuminated.

MAINTENANCE

1. 

Isolate the Wolf LinkEx™ LED Temporary Luminaire from the power supply before 

carrying out any maintenance work.

2. 

To replace LED strip, replace entire tray (see spares list).

3. 

External plastic components have an anti static coating. Use only a dilute water/

detergent mix to clean.

4. 

IMPORTANT. No modifications are permitted to the Wolf LinkEx™ LED Temporary 

Luminaire, all spare parts must be purchased from the manufacturer, unauthorized 

modifications or spare parts will invalidate certification. 

5. 

Insulation testing must be carried out to IEC, EN standards to the correct rating 

i.e. 250V DC for 24/48V versions and 500V DC for 110/230VAC versions, Live 

and neutral cables must be shorted together and the voltage applied between 

earth and this connection.

ELECTRICAL DATA

 

 

CHANGING CABLE OR SOCKETS

See attached diagrams.
Remove the two securing screws from the cable entry end cap, remove end cap. 

Disconnect the input cable. To remove the enclosure tube, slide tube over the tray 

assembly. With the tube removed the blank cap (non linkable Luminaire) or socket  

and cap (linkable Luminaire) can be removed by removing the two internal screws; care 

must be taken to retain the sealing washers fitted to the screws and dome nuts.  

If required the socket cap can then be removed, if the socket is replaced ensure correct 

sealing washers are used. Re-assembly is the reverse procedure.  

Take care not to trap/crush wires, ensure all seals are present and in good condition.

FAULT FINDING

If a Wolf LinkEx™ LED Temporary Luminaire fails to function, check input cable 

continuity and terminations.  If satisfactory, test the output fuse to each LED strip. Only 

replace with Wolf encapsulated fuse of the correct rating. On 24/48V versions replace 

all fuses to LED strips if either has failed.
