I. Introduction
This publication contains the information needed to install medium voltage eVM1 (withdrawable
version for UniGear ZS1 type switchgear and PowerCube modules) and put them into service.
For correct use of the product, please read it carefully.
Like all the apparatus we manufacture, the eVM1 circuit-breakers are designed for different instal-
lation configurations.
However, they do allow further technical and construction modifications (at the customer’s re-
quest) to adapt to special installation requirements.
For this reason, the information given below may sometimes not contain instructions concerning
special configurations.
Apart from this manual, it is therefore always necessary to consult the latest technical documen-
tation (circuit and wiring diagrams, assembly and installation drawings, any protection coordina-
tion studies, etc.), especially regarding any variants requested in relation to the standardised
configurations.
Only use original spare parts for maintenance operations.
For further information, please also see the technical catalogue of the circuit-breaker.
All the installation, putting into service, running and maintenance operations must be car-
ried out by skilled personnel with in-depth knowledge of the apparatus.
II. Environmental protection programme
The eVM1 circuit-breakers are manufactured in accordance with the ISO 14000 Standards (Guide-
lines for environmental management).
The production processes are carried out in compliance with the Standards for environmental
protection in terms of reduction in energy consumption as well as in raw materials and production
of waste materials. All this is thanks to the medium voltage apparatus manufacturing facility envi-
ronmental management system.

1. Packing and transport
The circuit-breaker is shipped in special packing, in the open position.
Each piece of apparatus is protected by a plastic cover to prevent any infiltration of water during
the loading and unloading stages and to keep the dust off during storage.
2. Checking on receipt
Before carrying out any operation, always make sure that the capacitors are discharged
and that the apparatus is in the open position.
On receipt, check the state of the apparatus, integrity of the packing and correspondence with the
nameplate data (see fig. 1) with what is specified in the order confirmation and in the accompany-
ing shipping notes.
Also make sure that all the materials described in the shipping notes are included in the supply.
Should any damage or irregularity be noted in the supply 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 ordering and vali-
dated in the order confirmation sent by ABB.

3. Storage
When a period of storage is foreseen, our workshops can (on request) provide suitable packing
for the specified storage conditions.
On receipt the apparatus must be carefully unpacked and checked as described in Checking on
receipt (chap. 2).
If immediate installation is not possible, the packing must be replaced, using the original material
supplied.
Insert special hygroscopic substances inside the packing, using at least one standard packet per
piece of apparatus.
Should the original packing not be available and immediate installation is not possible, store in a
covered, well-ventilated, dry, dust-free, non-corrosive ambient, away from any flammable materi-
als and at a temperature between –5 °C and +45 °C.
In any case, avoid any accidental impacts or positioning which stresses the structure of the appa-
ratus.
4. Handling
Before carrying out any operations, always make sure that the capacitors are discharged.
To lift and handle the circuit-breaker, proceed as follows (fig. 2):
– use a special lifting tool (1) (not supplied) fitted with ropes with safety hooks (2);
– insert the hooks (2) in the supports (3) fixed to the frame of the circuit-breaker and lift. Latch the
hooks (2) into the support holes (3) according to the type of apparatus (see table);
– on completion of the operation (and in any case before putting into service) unhook the lifting
tool (1) and dismantle the supports (3) from the frame.
During handling, take great care not to stress the insulating parts and the terminals of the circuit-
breaker.

5. Description
The eVM1/P type vacuum circuit-breakers are designed for indoor installation in air-insulated
switchgear.
In respect of the technical characteristics, eVM1/P circuit-breakers are suitable for operation of
electric circuits under normal and fault service conditions.
The vacuum circuit-breakers have particular advantages when used in systems with a high fre-
quency of operations and/or which lead to a certain number of short-circuit trips.
The eVM1/P type vacuum circuit-breakers stand out for their particularly high operating reliability,
extremely long useful life expectancy and for being completely maintenance-free.
The eVM1/P type vacuum circuit-breakers are available in the withdrawable version. Their basic
structure is shown in the “Technical data” section.
5.1. Standards and regulations
5.1.1. Fabrication
The eVM1 circuit-breakers conform to the following Standards:
• VDE 0670, part 1000, and IEC 60694
• DIN VDE 0670, part 104, and IEC 62271-100
• DIN VDE 0847, part 4, and IEC 61000-4.
The apparatus must not be handled by putting lifting devices directly under the apparatus
itself. Should it be necessary to use this technique, put the circuit-breaker onto a pallet or
a sturdy supporting surface (see fig. 3).
In any case, it is always advisable to carry out lifting using the supports (3). Hole “D” must
never be used.
