*Some variants of plugs/sockets may reduce the IP (Ingress Protection) rating.
e.g. ATX and CEAG IP66, Stahl Sockets IP54 rated.

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.

Wolf Safety Lamp Company Ltd.

***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.

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.
