1. RECEPTION, HANDLING, INSTALLATION
1.1. Unpacking
Relays must only be handled by qualified personnel and special care must be taken to protect all of
their parts from any damage while they are being unpacked and installed. The use of good
illumination is recommended to facilitate the equipment visual inspection.
The facility must be clean and dry and relays should not be stored in places that are exposed to dust
or humidity. Special care must be taken if construction work is taking place.
1.2. Reception of relays
It is necessary to inspect the equipment at the time it is delivered to ensure that the relays have not
been damaged during transport.
If any defect is found, the transport company and FANOX should be informed immediately.
If the relays are not for immediate use, they should be returned to their original packaging.
1.3. Handling electronic equipment
Relays contain an electronic component that is sensitive to electrostatic discharges.
Just by moving, a person can build up an electrostatic potential of several thousand volts.
Discharging this energy into electronic components can cause serious damage to electronic circuits.
It is possible that this damage may not be detected straight away, but the electronic circuit reliability
and life will be reduced. This electronic component in the equipment is well protected by the metal
housing, which should not be removed as the equipment cannot be adjusted internally.
If it is necessary to disassemble the electronic component, this must be carried out with care and
contact with electronic components, printed circuits and connections must be avoided to prevent an
electrostatic discharge that could damage one of the components. If the electronic components are
stored outside the metal housing, they must be placed in an antistatic conductive bag.
If it is necessary to open a module, care must be taken to preserve the equipment reliability and the
duration of the life cycle as designed by the manufacturer by taking the following actions:
•Touch the housing to ensure that you have the same potential
•Avoid touching the electronic components and handle the module by its edges.
•Remember that everyone who handles the module must have the same potential.
•Use a conductive bag to transport the module.
For more information about how to handle electronic circuits, consult official documents such as the
IEC 147-OF.
1.4. Installation, commissioning and service
The personnel in charge of installing, commissioning and maintaining this equipment must be
qualified and must be aware of the procedures for handling it. The product documentation should be
read before installing, commissioning or carrying out maintenance work on the equipment.
Personnel should take specific protection measures to avoid the risk of electronic discharge when
access is unlocked on the rear part of the equipment.

ISO 9001:2008
In order to guarantee safety, the crimp terminal and a suitable tool must be used to meet isolation
requirements on the terminal strip. Crimped terminations must be used for the voltage and current
connections.
It is necessary to connect the equipment to earth through the corresponding terminal, using the
shortest possible cable. As well as guaranteeing safety for the personnel, this connection allows high
frequency noise to be evacuated directly to earth.
The following checks must be performed before the equipment is supplied:
•The rated voltage and polarity.
•The power rating of the CT circuit and the integrity of the connections.
•The integrity of the earth connection.
The equipment must be used within the stipulated electrical and environmental limits.
Note: Regarding the current transformer circuits: Do not open a live CT secondary circuit. The high
voltage produced as a result could damage the isolation and threaten lives.
1.5. Storage
If the relays are not going to be installed immediately, they must be stored in a dust- and humidity
free environment after the visual inspection has been performed.
1.6. Recycling
Before recycling the equipment, the capacitors should be discharged through the external terminals.
All electrical power sources should be removed before performing this operation to avoid the risk of
electrical discharge.
This product must be disposed of in a safe way. It should not be incinerated or brought into contact
with water sources like rivers, lakes, etc…

3. DESCRIPTION
3.1. Introduction
Worldwide, the energy sector is currently undergoing a profound change as a result of high levels of
energy demand; more distribution lines and advanced supervision systems are required. Given the
need for creating intelligent infrastructure, FANOX has developed the SIA family of products to carry
out this function.
The family of SIA relays is designed to protect the secondary transformation and distribution centres
of electricity grids. Protection features include protection against instantaneous and inverse time
overcurrent (for the phases and the neutral), and it also has external trip support (temperature,
pressure, etc.) depending on the characteristics of each model.
The protection functions can be enabled selectively by using both the front panel and the
communications links to the SIcom program, allowing for precise coordination with other equipment.
Additional benefits include that all of the models have been designed to be supplied from an external
battery. This is aimed at facilitating event management and the commissioning of centres, as well as
allowing it to operate properly under adverse conditions.
3.2. Equipment description
The SIA-D equipment is a protection relay designed for secondary distribution.
It is supplied with 110-230 Vac / 90-300 Vdc auxiliary voltage. It is possible to choose 24-48 Vdc
auxiliary for each model. As for the rest of the SIA family, it can be supplied through its front RS-232
communications port via an external battery, using the KITCOM adapter. This facilitates the start-up
of the centres and the management of events. The operation of the outputs is not guaranteed when
the SIA-D equipment is supplied from an external battery.
As well as the functions to protect against instantaneous phase and neutral overcurrents and phase
and neutral inverse time overcurrents, it is possible to choose two neutral directional units or one
isolated neutral directional unit for each model. It is also equipped with a trip blocking to protect the
switchgear in centres that combine switchgear and fuses.
All models include a breaker management block, which monitors the switch condition, the number of
breaks and the accumulated amps. It generates an indication if these are excessive, it determines
whether or not an Opening fault has occurred and allows the breaker close and open commands
from the HMI and via the communications port (either locally or remotely).
Revision B includes in all the models two new characteristics:

www.fanox.com SIA-D_Rev. 07 14 / 117
ISO 9001:2008
•A general states bit which monitories 48 Vdc power source
•Tripping Bus (which requires two inputs and two outputs)
The SIA-D equipment has four inputs and four outputs
that can be configured by the user.
In order to facilitate the analysis of events, it is fitted
with two oscillographic records, each one with 33
cycles: 3 prefault cycles and 30 postfault cycles.
The oscillograph start can be configured by the user.
Each oscillographic record shows the phase and
neutral currents, the neutral voltage and up to 64 digital
channels, which include pick-ups and trips of the
protection functions, inputs, outputs, etc. The
COMTRADE format is used (IEEE C37.111-1991).
The SIA-D equipment is housed in a metal box with
galvanic isolation on all of its measurement or digital
inputs and outputs (with the exception of ports for
communications and battery power supply, as these are
sporadic connections). This allows the equipment to
have the best possible level of electromagnetic
compatibility, both in terms of emission of, and immunity from, radiated and conducted interferences.
These levels are the same as those established for primary substations.
The equipment has a LCD with two lines and twenty columns and a membrane keyboard with six
buttons. These allow the display of the equipment status, the current measurements in the primary
and the events or incidents associated with the equipment, and adjustments to be made to the
protection criteria. Depending on the model, these events can be saved in a non-volatile memory to
save them in case of power failures.
There are three bistable magnetic indicators on the front of the SIA-D equipment. These indicate the
causes of trips, and continue to signal the indication even if the relay loses power. It is also fitted with
three LED indicators, which blink to show the type of supply that is being used at any time.
The equipment has storage for up to 500 events, allowing any recorded incidents to be analysed. All
SIA-D models are equipped with a real-time clock (RTC).
Current measurements are performed using RMS values, with an accuracy of 2%. Standard 5 A and
1 A current transformers (CTs) are used.
The equipment has two communication ports: a front port (RS232) and an optional rear port
(RS485). The RS232 port allows a PC to be connected, which can be used to monitor the equipment
using the SICom communications program (supplied by FANOX). A 12V battery can also be used to
power the equipment through this front port by using the adapter (KITCOM). The rear port RS485
allows the equipment to be integrated as part of a system (SCADA). The Modbus RTU protocol is
used in both ports. Setting-up a session allows four levels of access to be set up with passwords that
can be configured by the user.
The protective functions provided, easy-to-use interface, low amount of maintenance and simple
integration make the SIA-D a precise and practical solution for protecting both industrial and public
electrical grids and transformation and distribution centres. It even provides these protective
functions in situations where auxiliary power sources are not available or not reliable. The protection
offered by the SIA-D against earth faults is sensitive enough to be used in electric systems where the
earth fault current is low. It can be set to 0.2 times the rated neutral current and, depending on the
model, the rated neutral current can go as low as 0.1 A.
The main features of the equipment are listed below, and these features will be explained in the rest
of the manual:

In order to assure a correct running of the relay, it is necessary to use the proper current
transformer. Therefore, the load of measurement circuits of the relay and the load of connection
cables between CT’s and relay must be taken into account.
