5.1 Dispatch
At the time of dispatch, the UniGear panels are
factory-assembled, the withdrawable parts are in
the SERVICE position, the earthing switch is
opened and the doors are closed.
The factory-assembled panels are checked at the
works for completeness in terms of the order
and simultaneously subjected to routine testing
(normally without AC voltage testing of the
busbars) to IEC publication, and are therefore
tested for correct structure and function.
The busbars connecting the panels of a shipping
section are factory assembled. The remaining
busbar material, fasteners and accessories are
packed separately.
5.2 Packing
According to the kind of transport and country
of destination, the panels remain unpacked or
are wrapped in foil and packed in seaworthy
crates:
•
Panels with basic packing or without packing
•
Panels with seaworthy or similar packing
(including packing for containerised shipments):
- Sealed in aluminium composite foil wrap
- Transport drying agent bags included
5.3 Transport
The shipping section normally comprise a suite
of two or three panels. Only in exceptional cases
will an individual panel form a transport unit.
Each suite of panels is fitted with four lifting lugs.
Transport panels upright. Take the high centre
of gravity into account. Only ever carry out loading
operations when it has been ensured that all
precautionary measures to protect personnel
and materials have been taken and use the
following:
•
Crane
•
Fork-lift truck and/or
•
Manual trolley jack
Loading by crane:
•
Fit lifting ropes of appropriate load capacity
with spring catches (eyebolt diameter: 30 mm)
•
Keep an angle of at least 60° from the horizontal
for the ropes leading to the crane hook
5.4 Delivery
The responsibilities of the consignee when the
switchgear arrives at site include, but are not
limited to, the following:
•
Checking the consignment for completeness
and lack of any damage (e.g. for moisture and
its detrimental effects also). In case of doubt,
the packing must be opened and then properly
resealed, putting in new drying agent bags,
when intermediate storage is necessary
•
If any quantities are short, or defects or
transport damage are noted, these must be:
- documented on the respective shipping
document
- notified to the relevant carrier or forwarding
agent immediately in accordance with the
relative liability regulations
Note:
Always take photographs to document any
major damage.
5.5 Intermediate storage
Optimum intermediate storage, where it is
necessary, without any negative consequences
depends on compliance with a number of minimum
conditions for the panels and assembly materials.
5.5.1 Panels with basic packing or without
packing
•
A dry well-ventilated store room with a climate
in accordance with IEC
•
The room temperature must not fall below -5 °C
•
There must not be any other negative
environmental influences
•
Store the panels upright
•
Do not stack panels
•
Panels with basic packing:
•
Open the packing, at least partially
•
Panels without packing:
•
Loosely cover with protective sheeting
•
Ensure that there is sufficient air circulation
•
Check regularly for any condensation until
installation is started
5.5.2 Panels with seaworthy or similar packing
with internal protective sheeting
•
Store the transport units:
- protected from the weather
- in a dry place
- safe from any damage
•
Check the packing for damage
•
Check the drying agent (also see section 5.2):
on arrival of the consignment and
subsequently at regular intervals
•
When the maximum storage period, starting
from the date of packing, has been exceeded:
- the protective function of the packing can
no longer be guaranteed
- take suitable action if intermediate storage
is to continue
Note:
Do not walk on the roof of the panels (rupture
points in pressure relief devices!).
5.6 Handling
Before carrying out any operations, always make
sure that the operating mechanism spring is
discharged and that the apparatus is in the open
position.
To lift and handle the circuit-breaker, proceed
as follows:
•
Use a universal lifting tool (not supplied) fitted
with ropes with safety hooks
•
On completion of the operation (and in any
case before putting into service) unhook the
lifting accessories from the frame
•
During handling, take great care not to stress
the insulating parts of the contactor truck
Caution!
The contactor truck must be handled as
recommended.
Should it be necessary to use this
technique, put the contactor onto a
pallet or a sturdy supporting surface.
It is always advisable to carry out lifting
using the supports.
5.6.1 Switchgear
The switchgear panels are usually fixed to wooden
pallets. Handling should be carried out by overhead
or mobile cranes. Otherwise, use rollers or fork
lift trucks.
Weights and dimensions of each section are listed
in the shipping documents and in the general
arrangement drawings.
5.6.2 Handling with overhead crane or mobile
crane and unpacking
The switchgear must be lifted by crane and
circular slings. The slings must engage with the
four lifting lugs on the shipping section.
Weight and lifting opening angle must be taken
into account when choosing the circular slings.
