IMPORTANT: SPECIAL CONDITIONS OF USE (X)

1. The user/installer shall ensure that, when the Luminaire is tted with a
previously certied 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 tted with Marechal sockets are certied for low impact risk

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

3. The LED Temporary Emergency Luminaire can be tted with a protective
cover (LX-621), when tted the maximum ambient temperature lowers from
+55°C to +45°C. Use only Wolf supplied accessories.

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.

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 xings or metal gland come into contact with local

metal work. In these situations, the luminaire should also be locally earth

bonded with a exible cable, no longer than 2 metres, with a conductor area of

6mm2 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 tted 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 certied 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.

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 tted. On the six way terminal block, tighten screws to 0.7Nm,

on the 4 way terminal block tighten to 1.8Nm.

8. ATEX/IECEx certied 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 tted with a previously certied plug or socket, the
covers must be closed to maintain their IP rating.

MAINTENANCE

1. IMPORTANT. Any maintenance work should be carried out in the safe area
only.

2. IMPORTANT. No modications are permitted to the LinkEx LED

leadlamps, use only genuine Wolf spare parts and accessories, unauthorised

modications, spare parts or accessories will invalidate certication.

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.

BATTERY CHARGE INDICATION

The battery status is indicated by two LED indicators that are situated on the
top of the driver. These LEDs are visible through the outer tube. See below for
charge indication breakdown.

If this emergency luminaire is relied upon for the safe evacuation of personnel,
it is the user’s responsibility to ensure that the performance of the emergency
mode is suitable for their needs. It is recommended that the duration of the
discharge is tested regularly and upon powering up, the luminaire indicates
“Battery Charging”. The full capacity of the battery is not available until the
unit indicates “Maintenance Charge / Battery Full”. Contact Wolf for further
information.

Battery Charge Time: 16 hrs

Deep Discharge Protection - The lamp will automatically cut off when the
battery reaches a pre-determined low voltage. The battery will need to be re­charged before the emergency mode is functional again.

Battery Storage - To maximise the performance of the emergency function it

is recommended that the battery is charged (for 16 hours) once a month. It is

imperative that the unit is charged every three months, otherwise permanent
loss of capacity might occur. In this case, the unit will not function as an
emergency luminaire and will indicate “Replace Battery”.

Recommended battery storage temp.: +5 to +25°C
