PACKAGING
& PROTECTION
BEFORE TRANSPORT
DELIVERY
Legrand advises you to protect the enclosures, and the equipment
that makes them up, with adequate packaging before delivery,
against possible damage during transport, dust and humidity
during storage.
We recommend the use of cardboard and plastic film (if possible,
use recyclable packaging). It is also possible to add wooden
structures to ensure better stability.
For sea freight we advise you to refer to the SEI4C standard,
and for air delivery we advise you to apply the IATA standard.
We advise you to deliver the enclosures with the bases. If the
bases are not provided, the delivery must be made with pallets
adapted to support the weight of the columns. The enclosures
must be fixed to the pallets.
In order to reduce the weight for each column, we recommend
to deliver the circuit breakers in plugged-in and draw-out
version, with the movable part of the IS 223/233/333 bases
separated. The original packaging of the product can be
reused. All products must be marked and identified to enable
correct installation on site. In general, equipment > 30 Kg must
be delivered separately and in its original packaging. Similarly,
precision or high-value instruments for measurement and
indication must be delivered separately. Fragile materials
(e.g. fluorescent tubes) must also be well protected and
delivered separately.
For a correct traceability and installation on arrival on the
site, it is important to inform beforehand all the necessary
information, at least:
- The manufacturer of the assembly
- The date of manufacture
- The name of the panel/enclosure with the number of the cells
if there are several (also indicate the right or left side of the
first cell)
- The identification of the departures
- The weight of each transportable part
- A warning on the heaviest side of each transportable part to
avoid tipping during handling
- Indications regarding the weight, center of gravity, top and
bottom, no impact and no tipping of the enclosures must be
clearly indicated on the packaging to the carrier.

LIFTING/HANDLING OF
ENCLOSURES/PANELS:
RINGS, ANGLE CROSSBARS,
ETC.
In addition to being provided with internal reinforcing elements
(not removable), particularly heavy panels can also be provided
with reinforcements (made by the customer), mounted under
the base, as shown in Fig. 1. We recommend that these
reinforcing elements are not removed until the final installation
on site.
Smaller enclosures are delivered on wooden pallets so that they
can be lifted with forklifts. The enclosures must be strapped
to the forklift trucks if they are to be moved over uneven,
chaotic ground, with holes or on external roads. For handling
operations, the panel must therefore be lifted by means of a
forklift truck, of suitable characteristics, from the lower part
of the pallet.
Fig. 1 - Reinforcements on XL³ 4000 enclosures
LIFTING A COLUMN WITHOUT A PALLET
When a column is not placed on a pallet or in the absence of
particular requirements, the lifting must be carried out by
means of a fork-lift truck or a pallet truck by the lower part,
after having removed the base covering (see photo below)
which must then be put back in place once the positioning is
completed.
For the lifting of larger enclosures (XL³ 4000/6300), we
recommend the use of Legrand lifting rings Cat.No 0 205 82.
The installer/panel builder takes full responsibility for the
use of any other means of handling (brackets, steel profiles,
crossbars, etc.).

LIFTING/HANDLING OF
ENCLOSURES/PANELS:
RINGS, ANGLE CROSSBARS,
ETC.
LIFTING WITH RINGS CAT.NO 0 205 82
These lifting rings are generally used for lifting cells with a width of less than 2 m. It is recommended to ensure that the angle
formed by the cables is always less than 45° at the edge of the eye and 15° in lateral traction (risk of breaking the ring if the angle
is exceeded), and that the cables and lifting equipment have sufficient reach.
During the lifting phase, it is necessary to check the maximum load allowed for the ropes used (Fig. 3A) as well as the angle
formed by them in order not to exceed the maximum allowed load.
LIFTING OF PANELS WITH ANGLE CROSSBARS
If the enclosure consists of several cells with a length of more than 2 m, handling operations can be carried out with the help of
angle crossbars (Fig. 3B).
This method is particularly applicable to XL³ 4000 enclosures. It is recommended to ensure that the cables and lifting equipment
are suitable and that the angle formed by the cables is less than 45°.

LIFTING/HANDLING OF ENCLOSURES/PANELS:
RINGS, ANGLE CROSSBARS, ETC.
The operator carrying out the lifting operation must take into account all the necessary measures in order to carry out this
operation in complete safety, and know all the following technical parameters:
- Maximum Operating Load of the sling: maximum load that the sling can support in current use,
- Slinging mode factor: factor applied to the maximum operating load of a single-strand sling to take into account the geometry of
the slinging (number and angles of the strands) and the consequence of the folding of certain components.
When using the lifting rings Cat.No 0 205 82, the hook must be inserted into the ring with the hook nose facing outwards:
During the lifting operation, the angle formed by the sling and the ring must be respected:
In the case of slinging on several rings, the following regulations must be observed:
- Use flange rings,
- The rings must be screwed all the way to the base,
- The contact between the ring base and the part to be lifted must be over the entire surface of the base,
- The ring must never be subjected to bending. The force must therefore be in the plane of the ring. The difficulty of matching the
orientation of the ring after tightening and the direction of the tensile force can be solved by using a swivel and articulated ring,
- Each strand of the sling should not deviate more than 45° from the vertical. Depending on the rings used, a reduction of the ring’s
Maximum Operating Load must be applied according to the angle. To exceed the 45° value, a special study is necessary,
- If the load is to be attached to the side walls by means of rings, swivel and articulated rings must be used. A space between the
ring and the load wall must be provided for the hook to be positioned correctly. Any contact of the sling with the load will result in
a loss of Maximum Operating Load.
- If a tilting operation of the load is necessary, swivel and articulated rings with ball bearings must be used in order to avoid shocks.

As seen on page 5, we recommend to mark the weight of each transportable part and this indication must be clearly visible.
The cells must be stored vertically in the truck, boat or other means of transport. They should then be securely fastened to the
structure of the means of transport with suitable straps so that they cannot move during the entire period of transport.
It is imperative to indicate the weight, the center of gravity, the top, the bottom, of each transportable part and to warn
on the heaviest side in order to avoid any tilting during handling.
The absence of shock and the prohibition of tipping of the enclosures must also be clearly indicated on the packaging
for the carrier.

Check when you receive the panel:
- all the material,
- any damage due to transport.
In the event of a problem, determine the extent, cause and origin, then immediately record on the delivery note the damage
observed and visible, the reservations, and report these to the forwarder concerned within a maximum of 5 working days in a
formal manner (acknowledgement of receipt).
Once the panel is positioned near the installation site, proceed
as follows:
• remove the packaging from the panel,
• remove the wooden structure that «wraps» and supports the
panel (Fig. 2),
• place the panel on the installation site and remove the wooden
pallets.

Legrand panels are normally delivered in transport units not
exceeding 3 m in length, in standard packaging adapted to the
transport and storage requirements.
Each control or verification of the material supplied must be
carried out within 5 days of delivery. In case of irregularity, ask
for the intervention of a technical and commercial manager.
The main operations to be carried out at the reception of the
panels are the following:
• locate the identification numbers of the enclosures
• control the layout of the equipment according to the project,
• check the attached documentation.
Any irregularity must be reported to the panel builder with
reference to the identification number on the panel plate.
The panels are supplied in packaging suitable for normal
conditions of transport and storage in a covered area for a short
period of time (60 days), unless the customer has expressed
particular requirements for packaging and transport.
In the event that installation is to take place over a longer
period, it is recommended that the panels be stored in a well-
ventilated area free from excessive temperature variations
and covered with a waterproof tarpaulin. In this case, it is also
recommended to place bags of hygroscopic substances inside
the panels to absorb any humidity that may be present and
to check the bags at regular intervals to ensure that they are
effective.
