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.

www.fanox.com Rev. 32 6/114
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.
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 centers 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 centers, as well as
allowing it to operate properly under adverse conditions.
3.2. Description
The SIA-B equipment is a protection relay designed for secondary distribution. One of its main
characteristics is the necessity of using specific current transformers for measurement and power
supply.
The equipment starts-up from 0.8xIsmin single phase and
0.4xIsmin three phase current using specific CTs.
The SIA-B equipment is housed in a metal box with
galvanic isolation on all its measurement 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 an LCD with two lines and twenty
columns and a membrane keyboard with six buttons.
These allow the display of the equipment state, the current
measurements in the primary and the events or incidents
associated with the equipment, and adjustments to be
made to the protection criteria.
There are two LED indicators on the front of the SIA-B
equipment. These indicate if the equipment is On (LED ON) and if an alarm has happened (LED
ALARM). Depending on model, there is a possibility of having, apart from the LEDS, one bistable
indicator to signaling the trip of any of the protection functions. About signaling, there is a possibility of
selecting 2 signaling outputs configurable by the user.
The equipment has storage for up to 100 events, allowing any registered incidents to be analyzed.
RTC (Real Time Clock) is available for all SIA-B models.
To facilitate the analysis of events, it is fitted with 4 fault reports (24 events per fault report). Fault
reports start when any of the protection functions picks-up and it finishes when any of the mentioned
functions trips.

www.fanox.com Rev. 32 17/114
The equipment has storage for up to 100 events, allowing any recorded incidents to be analyzed. All
SIA-B models are equipped with a real-time clock (RTC) which permits registering all the events with a
reliable timestamp.
Current measurements are performed using RMS values. Specific current transformers (CTs) are
used.
The equipment has a frontal communication port (mini USB). This port allows a PC to be connected,
which can be used to monitor the equipment using the SICom communications program (supplied by
FANOX). Besides, the frontal port can be used to power the equipment by using an USB cable which
can be directly connected with PC. Remote communication is available depending on model (RS485
rear port - Modbus RTU protocol).
The protective functions provided, easy-to-use interface, low amount of maintenance and simple
integration make the SIA-B a precise and practical solution for protecting both industrial and public
electrical grids and transformation and distribution centers. The main features of the equipment are
listed below, and these features will be explained in the rest of the manual:
