1 Introduction
This publication contains the information needed to install medium voltage AutoLink
Sectionalizer and put it into service.
For a correct use of the product, please read it carefully.
Like every apparatus we manufacture, AutoLink is designed for different installation
configurations.
However, these pieces of apparatus do allow further technical and construction
modifications (at customer’s request) to adapt to special installation requirements.
Consequently, the information given here may sometimes not contain instructions
concerning special configurations.
Besides this manual, it is therefore always necessary to consult the latest technical
documentation (assembly and installation drawings, protection coordination studies, etc.),
specially regarding any variants requested in relation to the standardized configurations.
Only use original spare parts for maintenance operations.
For further information, please also see the technical catalogue and the spare parts
catalogue.
All installation, putting into service, commissioning and maintenance
operations must be carried out by suitably qualified personnel with in-
depth knowledge of the apparatus.
2 Packing and Transportation
The AutoLink Sectionalizer is shipped in cardboard package, in disarmed position.
Each piece of apparatus is protected by a plastic cover to prevent any infiltration of water
during loading and unloading stages, and to keep the dust off during storage.
3 Checking on Reception
Before carrying out any operation, always make sure that the operating
mechanism springs are discharged and that the apparatus is in disarmed
position.
On reception, check the state of the apparatus, integrity of the packing and
correspondence with the nameplate information along with the order confirmation
specifications and the accompanying shipping note.
Also make sure that all materials described in the shipping note 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 distributor) 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
validated in the order confirmation sent by ABB.

TEHI95094 – rev. 1 5 / 11
The accompanying documents inserted in the shipping packing are:
- Test Certification
- Packing List
Other documents which are sent prior to shipment of the apparatus are:
- Order confirmation
- Original shipping advice notes
- Any drawings or documents referring to special configurations/conditions
4 Storage
When a period of storage is foreseen, our workshops can (on request) provide suitable
packing for the specific storage conditions.
On receipt the apparatus must be carefully unpacked and checked as described in
Chapter 2 of this manual.
If immediate installation is not possible, the packing must be replaced, using the original
material supplied.
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 materials 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 apparatus.
5 Description
The AutoLink Electronic Sectionalizer is a protective device that operates at a permanent
failure in the distribution line. It must be used together with a backup recloser. Please
take note that the AutoLink is not a fuse tripping device, therefore it cannot be used as a
protective device by itself.
The AutoLink Electronic Sectionalizer is designed ONLY to protect electrical equipment
and NOT for saving people from accidents or electrocution when contacting energized
circuits.
6 Installation
6.1 General
Correct installation is of primary importance. The manufacturer’s instructions must
be carefully studied and followed. It is good practice to use gloves for handling the
pieces during installation.
6.2 Installation and service conditions
The following standards must be taken into particular consideration during installation and
service:

TEHI95094 – rev. 1 6 / 11
- IEC 60694
- IEC 61936: Electrical Installation
- ANSI C37 63: Automatic Sectionalizer
- All accident prevention regulations in force in relative countries
For special installation requirements or other operating conditions, please contact ABB.
6.3 Initial Setting or Previous Setting Modification Instructions
Remove the contact cap (Fig. 1 A) with a 34mm fork spanner holding the base (Fig. 1 B)
with the hand. Check condition of O-ring (Fig. 2 E), and replace if necessary, applying
grease on it.
Figure 1
With a small screwdriver, set the dip switches for calibrating current (Fig. 2 C, 4 switches)
and Counting Operations (Fig. 2 D, 2 switches), according to settings table 1.
Note: handle with care without forcing the switches. Settings must be made in a clean
and dry environment.

Once the calibration current and counts are selected, cover the dipswitch with a generous
amount of silicon grease (Fig. 3), supplied with AutoLink.
Figure 3
Check the condition of the O’Ring (Fig. 2 E) and apply silicon grease (Fig. 4 F) both
inside the cap and over the dip switches.

Place the cap, holding the tube with the hand, and tighten with a 34 mm fork spanner
(torque between 8 and 10 Nm) without damaging the O’Ring (Fig. 5).

6.4 AutoLink Repositioning
Push the interlocking bolt (Fig. 6) until blocked (it will spin freely, but it will not reset). Do
not strike the bolt, nor use any type of tool to reset.
Figure 6
Turn the tensioning device support (Fig. 7).
Place the tensioning device support facing the interlocking bolt.

Turn the tensioning device support 90°, until it is firmly blocked (Fig. 8)
Figure 8
Place the pole in the tube inferior eyelet (Fig. 9) and position in the isolating support
body.
Figure 9
Withdraw the pole and place it in the tube’s superior eyelet (Fig. 10). Push it until it
remains in closing position.

7 Commissioning
7.1 General procedures
All operations regarding commissioning must be carried out by suitably
qualified customer personnel with in-depth knowledge of the apparatus and
the installation itself.
Do not open the disconnecting switch under charge using a common pole, as
it could cause an arc that could damage the personnel or the equipment. The
disconnecting switch has horns to be used with a load break tool to carry out
this kind of operation.
8 Maintenance
Test the correct operation of electronic sectionalizer on a regular basis, preferably while
maintenance on head recloser is made:
- Check the closing system.
- Check that the interlocking bolt turns freely. The tensioning device support should move
easily and the spring should be sufficiently tightened so that the support may reset when
the system opens following the operation of the sectionalizer.
- Check that the mobile lever and the lower support of the AutoLink move easily at the
joint. Clean and lubricate the joint surfaces of both pieces.
- Keep contact zones clean and place a thin film of conductive grease on those zones.
Test should be carried out on a laboratory with the appropriate equipment to simulate
service conditions. For this operation it is recommended to contact ABB for requesting
testing procedures.
