WARNINGS
These instructions are provided to ensure appropriate storage, correct
installation, and efficient use of the system.
Note: carefully read these instructions upon receipt of the material and before
installing the system, and putting it into operation.
The installation must be completed by competent and suitably trained
personnel, as prescribed by CEI 11-27 and 50110-1:2004-11 (CEI 11-48)
standards, corresponding international standards, or specific applicable
standards of the individual countries of installation.
In order to guarantee the safety of personnel, the installation activities must
only be carried out with the power voltage disconnected, unless otherwise
stated.
WARNING
When working with electric systems, pay particular attention to the
risk of electric shock. Electric shocks can cause serious injury, or even
death.
NOTE: Do not tamper or perform modifications to products
manufactured by BTicino S.p.A. without written authorization by
manufacturer. BTicino S.p.A. does not authorize any kind of repairs. All
tampering, or modifications not authorized in writing by BTicino S.p.A.

STORAGE INSTRUCTIONS

HANDLING
When handling the material, comply with the regulations for safety in the
workplace pursuant Leg. Decree No. 81 dated 09/04/2008 (Consolidated act
on safety in the workplace).
Follow the indications supplied to prevent damage to materials, or risks to
personnel.
Below are the instructions to follow for a correct material handling.
1 Always pay the utmost attention when opening packages.
2 To open wooden cases, in which the materials are dispatched to protect
them, use a claw hammer.
3 Handle the busbars with due care and attention. Do not subject busbars to
torsions, dents, violent impact, or sharp movements that may damage their
internal components.
4 Do not lift the busbars from their ends. This could not just damage the
busbar, but also cause injury to the personnel carrying out the operation.
When using a crane to install the busbar, use nylon slings to balance the
weight.
5 Do not use belts or other systems to lift them to the junction windows, or
the expansion cap. This may damage the busbars.
6 When not installing the busbar immediately upon receipt, ensure appropriate
storage for the time required before installation, following the storage
instructions.
7 Do not drag the busbar along the floor. This could cause irreversible
damage.
8 To correctly move busbars, cranes may be used. These would enable to lift
the busbars from the floor very easily.

1 integrity of the packaging, and the goods, if delivered in a see-through
package
2 consistency of the material with the Delivery Note and the packing list, if
supplied
3 consistency of the material with the order acknowledgement details
In case of any disclaims, please inform us in writing following the instructions
found in the notifications section.
NOTIFICATIONS
In case of any disclaim, please forward your official complaint to the IT-
[email protected] e-mail address, including the notification form
MODZ017.
Ensure that the MODZ017 form is correctly filled in, as this will enable us to
answer more promptly to your notification. This means that all fields must be
completed, including a detailed description of the disclaim.
Whenever possible, with each notification, attach photos of the items affected.
When notifying that a wrong item has been received, please indicate the item
code no. found on the packaging, and the item code no. found on the part (if
possible include a photo of the labels).
In case of damaged material, attach photos of the affected part and the
packaging (if present).
In case of hidden damage (outer packing undamaged, material inside
damaged), or if the transport was the responsibility of BTicino, please contact
us immediately so that we may initiate a complaint procedure against the
freight forwarder.
We remind you that the maximum limit for a hidden damage complaint is 7
days from the receipt of goods.

We recommend that upon receiving the goods, the integrity of the packaging is
checked WITH THE FREIGHT FORWARDER PRESENT. If you find that the
packaging has suffered damage and/or collisions of varying degree, please
write MATERIAL RECEIVED DAMAGED on the Delivery Note, to enable us to
initiate a complaint procedure against the freight forwarder. If the freight
forwarder stops you from indicating on the Delivery Note that the goods have
been received in damaged condition, or from performing the visual inspection,
we suggest that you DO NOT ACCEPT THE DELIVERY. This procedure will
enable us to immediately initiate the complaint procedure against the freight
forwarder, and to quickly replace any damaged material received.
If the transport is at your charge, we recommend that you immediately issue a
complaint against the freight forwarder.
If you require technical support intervention from us, tick the appropriate box
in the MODZ017 form. We remind you that this technical support intervention
may entail a fee (ANIE tariffs, plus out-of-pocket expenses) in case of
installation problems and/or malfunctioning or damage caused by the
customer.
STORAGE
Below are the instructions to follow for a correct storage of the materials.
Failure to comply with the indications supplied may cause damage to the
materials, and make the product warranties void.
Store the material in a dry place, protected from weather conditions such as
rain and humidity, to prevent the formation of condensation inside the
busbars.
Also ensure that the busbars are protected from smoke, water, soil, mud, dust,
or dirt in general. Position the material in a way that prevents a physical
damage to it. We recommend not to store the busbars outside.
It is recommended that the material is stored indoor, in a dry location. In case
of storing the busbars outside for short-medium periods, ensure that it is
appropriately protected, to avoid accidental infiltration of water, which will
result in them being damaged.
The material can be transported and stored at a temperature between -25°C
and +55°C.

INSTALLATION INSTRUCTIONS
Before the installation, all material should be inspected for damage.
When installing the busbars comply with the following:
1 do not position the busbars near pipes containing liquids.
2 for the installation only use bracketing systems supplied by BTicino, and
follow the instructions found in the catalogue or enclosed with the item.
3 only use accessories supplied by BTicino.
4 check that the operating voltage coincides with that indicated on the product
plate.
5 check that the system operating current does not exceed the product rated
current, downgrading it if required.
6 check if the busbar capacity must be downgraded (for example due to high
ambient temperature, presence of harmonics, etc.)
7 do not install the standard product in particular environments (high
concentration of chlorine, explosive atmosphere, etc.).
8 for outdoor installations, protect the busbar with a protection canopy. The
IP55 protection degree can be affected by unsuitably protected outdoor
installation.
9 Should the load of the conductors with current “I” be near the nominal
capacity , the possibility of electrical disturbance must be accounted for.
10 The area in which the busbar is to be installed must be assessed to see if it
is suitable for the type of product that has been chosen ( proximity to
excessive heat sources, presence of corrosive fumes, etc).
