LL-260/(suffixes define enclosure, cable, plug, socket and fuse options)
The Wolf ATEX splitter box 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 Splitter Box range use GRP and 316 stainless steel enclosures
protected with a 316 Stainless Steel Skid. The splitter box is approved as Group
II, equipment for use in zone 1 & 2 potentially explosive gases, vapours and
mists where a T5 temperature class is permitted and in zone 21 & 22 dusts
where the surface temperature T90ºC permits. ATX, CEAG, STAHL or
Marechal sockets may be fitted. SY, SB and HOFR can be used when
connecting into the splitter box via approved glands.

IMPORTANT
1.
Read the instruction leaflet carefully before commencing to use the
splitter box and retain it for future use.
2.
Check the rating label to ensure the splitter box is suitable for the
supply voltage, T class, ambient temperature present and IP rating.
3.
Splitter boxes constructed from GRP (Glass Reinforced Polyester) and
their mounted sockets are plastic, the end user must ensure that these
materials are suitable for the atmosphere the splitter box will be used
in. Excessive force should not be used on plastic components.
4.
The Splitter box must not be opened when energised and if fitted with
a fuse, a delay of 5 mins after disconnection from the electrical supply
must be observed before opening.
5.
Splitter Box must not be moved whilst energised. Always disconnect
the Splitter Box from the electrical supply before moving.
USER GUIDANCE FOR WOLF SPLITTER BOXES
1.
This product is Class 1 equipment and must be earthed.
2.
It is the user's responsibility to ensure there is no potential difference
between the earth supply to the splitter box and the earth where it is
sited. Where this is not possible the splitter box should also be locally
earth bonded. A flexible cable with a conductor area of 6mm
2
minimum
which is no longer than two metres is recommended for this. The
splitter box must be de-energised during connection or disconnection
of the local earth bond.
3.
The user must consider the effect of voltage losses on the input cable
to the splitter box, to ensure that products connected to the splitter box
are operating within their specified voltage tolerance.
4.
The supply cable must be inspected on a regular basis to ensure there
is no damage to the cable or gland.
5.
Splitter boxes have terminal blocks suitable for up to 4mm
2
live, neutral
and earth.
6.
Approved cable glands must be used and be suitable for the type of
cable used and the environment to be used in.
7.
Do not overload the source supply. It is the user's responsibility to
ensure products connected to the splitter box do not exceed the 15A
maximum input current rating of the splitter box.
8.
If the Wolf Splitter Box is fitted with a fuse, it will be an IEC 60269,
80kA breaking capacity cartridge fuse. The fuse type and maximum
value must not be exceeded. Replace with like for like fuse and secure
the screwed cover on fully.
Details of the fuse fitted is found on the splitter model
identification label which is attached to the lid
Replacing these with fuses of a different type or of a higher rating could
result in an unsafe condition occurring in the safe or hazardous area.
To prevent nuisance tripping, the total power of apparatus operated
from the splitter box should not exceed the rated maximum amperage
of the fuse. Where apparatus other than Wolf lighting products are
connected, its load should be checked to ensure it is suitable for use
with type gG (general) fuses.
9.
Where the splitter box is connected to a Wolf Safety ATEX transformer,
ensure that the connected circuits do not exceed total maximum
loading and maximum cable lengths permissible (see transformer
instructions for details). When calculating the maximum cable length,
the total must include the length of the splitter box input cable. Where
cables with different conductor areas are combined, the maximum
cable length should be selected based on the smallest conductor area.
Exceeding recommended cable lengths could result in an unsafe
condition in the safe or hazardous area in the event of a fault occurring.

MAINTENANCE
1.
Disconnect the splitter box from the electrical supply before carrying
out any maintenance.
2.
It is essential that the splitter is maintained in accordance with the
requirements of EN60079-17
3.
A visual check should be carried out to ensure all internal cables are
in good condition, and not suffering any sign of damage or
degradation. All internal connections should be checked to ensure that
they are correctly secured.
4.
The splitter box input cable and any attached cables should be
inspected before each use. Any damaged cables should be replaced
immediately.
5.
The condition of the gaskets on the enclosure and sockets should be
inspected to ensure there is no breakdown in the units IP rating.
6.
IMPORTANT.
No modifications are permitted to the splitter box or
sockets.
