3. In areas where processes that induce circulating currents in the earth
system are being undertaken, such as 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 lamp’s 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 metres, with a conductor area of
6mm
2
minimum. The luminaire must be de-energised from the mains supply
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 Optimal Voltage Indicator (SOVI). The Wolf LX-400E LED Leadlamp
incorporates SOVI technology to highlight to the user if the product is operating
outside of the certified maximum and recommended minimum voltage range.
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 uninterrupted beam to a pulse.
EU Declaration of Conformity
The Wolf ATEX LX-400E LinkEx LED Temporary Emergency Luminaire meets all
relevant provisions of the 2014/34/EU Explosive Atmospheres (ATEX Equipment)
Directive by virtue of the issued EU type examination certificate, confirming
compliance with all relevant harmonised standards and essential health and
safety requirements.
The Wolf ATEX LinkEx LED Temporary Emergency Luminaire is a leadlamp with
an emergency illumination function powered by a NiMH rechargeable battery
and is normally powered by a cabled 18-55AC or 90-264AC power source. It
is constructed with a durable enclosure construction of polycarbonate with
polyurethane protective rings. Approval is as Group II, Category 2 equipment for
use in zone 1 & 2 potentially explosive gases, vapours, mists and dusts where
the T4 temperature class/135ºC maximum surface temperature permits.
Certification/Approval Code:
Ex eb mb op is IIC T4 Gb
Ex tb op is IIIC T135°C Db IP6X
Ta = -20°C to +55°C
or Ta = -20°C to +45°C when the LX-621 optional Protection Cover is fitted

EN60079-28:2015, EN60079-31:2014
Ingress protection level IP67 to EN60529:1992
Some variants of plugs/sockets may reduce the Ingress Protection rating.
e.g. ATX & CEAG IP66.
ATEX LinkEx LED Leadlamps are certified compliant with the 2014/30/EU EMC
Directive to the harmonised standards: - EN 55015: 2013 +A1:2015,
EN 61547: 2009, EN 61000-3-2:2014, EN 61000-3-3:2013
If connecting a large number of lamps 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 indicating an unsafe
voltage, it is recommended that the lamp be switched off until it can be made
to operate at a correct voltage.
5. The LinkEx LED leadlamp enclosure is constructed from polycarbonate, the
end user must ensure suitability of the atmosphere the LinkEx LED leadlamp
will be used in.
6. The LinkEx LED leadlamp is class 1 earthed electrical equipment, using 3
core cable. This product must be earthed.
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 0.7Nm,
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 LinkEx LED leadlamps
will be used in, standard SY cable is not rated for use below 0ºC.
10. Inspect cable 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. Lamps must not be opened in Hazardous Areas.
13. When the LinkEx LED leadlamp is used in temporary installations
two mounting points must be used, see Wolf clamp rings and associated
accessories.
14. LinkEx LED leadlamps can be carried whilst energised/illuminated.
15.
When the Luminaire is fitted with a previously certified plug or socket, the
covers must be closed to maintain their IP rating.

IMPORTANT: SPECIAL CONDITIONS OF USE (X)
1. The user/installer shall ensure that, when the Luminaire is fitted with a
previously certified plug or socket 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 lamps fitted with Marechal sockets are certified for low impact risk
use only, do not expose to shocks greater than 4 joules.
3. The LED Temporary Emergency Luminaire can be fitted with a protective
cover (LX-621), when fitted the maximum ambient temperature lowers from

PHOTOBIOLOGICAL SAFETY
Floodlites are risk group 1 - No photobiological hazard under normal
behavioural conditions.
EQUIPMENT USE
1. This product incorporates an emergency function which allows the lamp to
illuminate at a reduced level in the event of supply failure. The batteries will
charge when the lamp is powered.
2. Check the rating label to ensure the LinkEx LED leadlamp is suitable for
the supply provided, ambient temperature present and the environmental
conditions.
MAINTENANCE
1. IMPORTANT. Any maintenance work should be carried out in the safe area
only.
2. IMPORTANT. No modifications are permitted to the LinkEx LED
leadlamps, use only genuine Wolf spare parts and accessories, unauthorised
modifications, spare parts or accessories will invalidate certification.
3. Isolate the LinkEx LED leadlamps from the power supply before carrying out
any maintenance work. Please note that the battery pack will remain live after
the leadlamp is isolated from the power supply, even when in deep discharge
mode.
4. In case of fault indication, remove and restore external power. If fault
indication persists, contact Wolf noting the LED indications both whist external
power is applied and whilst disconnected. Any faults should be repaired prior
to storage.
5. To replace LED strip, replace entire tray (see spares list).
6. External plastic components have an anti-static coating. Use only a dilute
water/detergent mix to clean.
7. Insulation testing must be carried out to IEC, EN standards to the correct
rating i.e. 250V DC for 18-55V and 500V DC for 90-264V versions. Live and
neutral cables must be shorted together and the voltage applied between earth
and this connection.
