1. Introduction
This document contains the required information 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 specific applications.
Use only original spare parts.
For further information, please read the technical 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 armed position.
3. Checking on Reception
Before carrying out any operation, always make sure that the
operating mechanism springs are charged and that the apparatus is in
armed position. When performing a reception test, it is required to
wait 5 minutes with the device de-energized after a tripping operation,
to reset it.
On reception, check the state of the apparatus, integrity of the packing and nameplate
information is the same requested on the purchase order specifications.
Make sure that all materials described in the shipping note are included in the supply.
If any damage or irregularity is seen in the supplied product after unboxing, notify ABB
(directly or through the agent or distributor) assoon as possible within five days of receipt.
The apparatus is only supplied with the accessories specified at the time of ordering and
validated in the order acknowledgement sent by ABB.
The documents sent in the shipping packing are:
- Test Certification
- Packing List
Other documents which are sent prior to shipment of the apparatus are:
- Order acknowledgement
- Original shipping advice notes
- Any drawings or documents referring to special configurations/conditions

TEHI95094 –Rev. 2 5/ 12
4. Storage
When the apparatus is unboxed, it must be carefully unpacked and checked as described
in Chapter 3 of this manual.
If immediate installation is not possible, the product should be kept in its original packing.
If immediate installation is not possible, store the equipment on its original packaging in a
covered, well-ventilated, dry, dust-free, non-corrosive ambient, away from any flammable
materials and at a temperature between -5°Cand +45°C.
In any case, avoid any accidental impacts or positioning which stresses the apparatus.
5. Description
The AutoLink Electronic Sectionalizer is a protection device that operates at a permanent
fault in the distribution line. It must be used together with a upstream recloser. Please take
note that the AutoLink is not a fuse tripping device, therefore it cannot be used as a
protection 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 very important. 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:
- IEC 60694
- IEC 61936: Electrical Installation
- ANSI C37 63: Automatic Sectionalizer
- All accident prevention regulations in relative countries
For special installation requirements or other operating conditions, please contact ABB.

TEHI95094 –Rev. 2 6/ 12
6.3 Initial Setting or Previous Setting Modification Instructions
Remove the top cap (Fig. 1 A) using a 34mm fork spanner holding the tube with the hand
(Fig. 1 B). Check condition of O-ring (Fig. 2 E), and replace it if necessary, applying grease
on it.
Set the dip-switches to calibrate the current (Fig. 2 C, 4 switches) and set counting
operations (Fig. 2 D, 2 switches) using a small screwdriver according to table 1 settings.
Note: handle with care without damaging the switches. Settings must be made in a clean
and dry environment.

TEHI95094 –Rev. 2 7/ 12
6.4 Dip-Switch Configuration
Once the calibration current and counts are set, cover the dip-switch with silicon grease
(Fig. 3), supplied with AutoLink.
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.

TEHI95094 –Rev. 2 8/ 12
Place the cap, holding the tube with the hand, and tighten it using a 34 mm fork spanner
(torque between 8 and 10 Nm) without damaging the O-Ring (Fig. 5).
6.5 AutoLink Repositioning
Push the interlocking bolt (Fig. 6) until blocked (it will rotate freely). Do not strike the bolt,
nor use any type of tool to reset.
Turn the tensioning device support (Fig. 7).
Place the tensioning device support facing the interlocking bolt.

TEHI95094 –Rev. 2 9/ 12
Turn the tripping pin 90°, until the lower contact is firmly blocked (Fig. 8)
Place the pole in the tube inferioreyelet (Fig. 9)and position in the cutout-base.

TEHI95094 –Rev. 2 10/ 12
Withdraw the pole and place it in the tube’s superior eyelet (Fig. 10). Push it until it remains
in closing position.

TEHI95094 –Rev. 2 11/ 12
7. Commissioning
7.1 General procedures
When commissioning, all operations must be carried out by suitable
qualified customer personnel with in-depth knowledge of the
apparatus and the installation itself.
It is not recommended to open AutoLink under charge using a
common hookstick, as it could cause an arc that might damage the
personnel or the equipment. The AutoLink has horns to be used with a
load break tool. There is also a LoadBreak AutoLink for opening under
load.
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.
- Keep the tripping pin clean.
- Check the upper contact cap is correctly fastened and both the o-ring and the silicon
grease are present.
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 to request the
testing procedure.
