I. Introduction
This publication contains the information necessary for
installation and putting into service of HD4 medium voltage
circuit-breakers.
For correct usage of the product, please read this manual
carefully.
For correct mounting of accessories and/or spare parts
please refer to the relevant instructions.
Like all the apparatus manufactured by us, the HD4 circuit-
breakers are designed for different installation configurations.
They do, however, allow further technical-constructional
variations (at the customer’s request) to suit special
installation requirements.
For this reason, the information given below does not always
cover special configurations.
Apart from this booklet, it is therefore always necessary to
refer to the latest technical documentation available (circuit
diagram, wiring diagrams, assembly and installation drawings,
any studies of protection co-ordination, etc.), especially with
regard to any variations from standardized configurations
requested.
All the operations regarding installation, putting
into service, operation and maintenance must be
carried out by suitably qualified personnel with in-
depth knowledge of the apparatus.
Only use original spare parts for maintenance operations.
For further information, also see the technical catalogue of the
circuit-breaker and the spare parts catalogue.
II. Programme for the environmental
protection
The HD4 circuit-breakers comply with ISO 14000 Standards
(Guidelines for the Environmental Management).
The production system of the Medium Voltage factories
complies for the environmental protection in terms of energy
consumption, raw materials and waste.
The environmental impact of the product life cycle is assessed
by the LCA - Life Cycle Assessment procedure, which is also
the result of a well-focused project phase in the selection of
materials, processes and packaging.
The Product environmental declaration is available for the
HD4 circuit-breakers
Production techniques are carried out in order to achieve
an easy dismantling and separation of the components at
the end of the circuit-breaker life cycle, while optimizing the
recycling process.

1. Packing and transport
The circuit-breaker is shipped in special packing in the open
position with the springs discharged and with absolute pole
pressure corresponding with the service value.
Each piece of apparatus is protected by a plastic film to
prevent any infiltration of water during the loading and
unloading stages and to keep the dust off during storage.
Handling and transport must only be carried out by expert
and properly trained personnel.
Do not remove or alter the switch identification contents and
labels.
Switches subject to UN3164 standards for transportation by
air and / or sea.

Before carrying out any operation, always make
sure that the operating mechanism dprings are
discharged and that the apparatus is in the open
position.
On receipt, check the state of the apparatus, that the packing
is undamaged and that the nameplate data corresponds (see
fig. 1) with that specified in the order acknowledgement and
in the delivery note.
Also make sure that all the materials described in the shipping
note are included in the supply.
If any damage or irregularity is discovered on unpacking,
notify ABB (directly or through the agent or supplier) as soon
as possible and in any case within five days of receipt.
The apparatus is only supplied with the accessories
specified at the time of order and confirmed in the order
acknowledgement sent by ABB.
The following accompanying documents are inserted in the
shipping packing:
– Instruction manual (this document)
– Test certificate
– Identification tag
– Fiscal copy of shipping note
– Electrical diagram
These other documents are sent prior to shipment:
– Order acknowledgement
– Original copy of shipping note
– Any drawings or documents regarding special
configurations/conditions.
2. Checking on receipt
7
3. Storage
In case a storage period is foreseen, on request our
workshops will provide a suitable packing to the specified
storage conditions.
On receipt, the apparatus must be carefully unpacked and
checked as described in chapter 2: Checkink on receipt.
If immediate installation is not possible and the circuit breaker
has to be re-stored again, it is necessary to restore the
packaging at least suitable for protection against dust.
Insert hygroscopic substances in the packaging in the
quantity of at least one standard pack per apparatus.
Therefore, store in a sheltered, well-ventilated area with a
dry, non-dusty, non-corrosive atmosphere away from highly
flammable materials, with a temperature between -5 °C and
+45 °C.
In any case, avoid accidental shocks or accommodations that
stress the structure of the circuit breaker.

4. Handling
Before carrying out any operation, always check that the
operating mechanism springs are discharged and that the
apparatus is in the open position.
Circuit-breakers up to 24 kV
– To lift and handle the circuit-breaker, use the tool (1) (fig. 2a:
shortest hooks for circuit-breakers up to 17.5 kV; all hooks
for 24 kV circuit-breakers).
– Put the hooks (2) in the holes prepared in the circuit-breaker
frame and lift.
– On completion of the operation (and in any case before
putting into service) unhook the lifting tool (1) (fig. 2b) and
dismantle the crosspiece (2) by unscrewing the screws (3).
Fig. 2a
36 kV circuit-breakers
– Attach the tools (1) to lift and handle the circuit-breaker
(fig. 2c);
–Attach the hooks (2) as illustrated in fig. 2d and lift;
– On completion of the operation, remove the tools (1).
Always take great care during handling not to stress the
insulating parts and the circuit-breaker terminals.
The apparatus must not be handled by inserting
lifting devices directly under the apparatus itself.
Should it be necessary to use this method, place
the circuit-breaker on a sturdy supporting surface
(see fig. 3).
