1 RECEPTION, HANDLING, INSTALLATION
1.1 Unpackaging
Relays must only be handled by qualified personnel and special care must be taken to protect all their
parts from any damage while they are being unpacked and installed.
The use of good illumination is recommended to facilitate the relay visual inspection.
The facility must be clean and dry. 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 device 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. This damage
may not be detected, but the electronic circuit reliability and life will be reduced. The electronic
component in the device is well protected by the metal housing, which should not be removed as the
device 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 electrostatic
discharges 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 device reliability and the duration
of the life cycle as designed by the manufacturer, 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.04 6/112
1.4 Installation, commissioning and service
The personnel in charge of installing, commissioning and maintaining this device 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 relay.
Personnel should take specific protection measures to avoid the risk of electronic discharge when
access is unlocked on the rear part of the relay.
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 device 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 device 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 device 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 resulting
high voltage 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 device, capacitors should be discharged through their 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.
Fanox Electronic, S.L. adheres itself to the 1st additional disposal of the Spanish 11/97 Standard in
which it is said that the final user of the containers should give them, properly segregated by materials,
to an authorized recovery, recycler or valuer company.

3 DESCRIPTION
3.1 Introduction
The energy sector is currently immersed in a deep change worldwide. As a result of high levels of energy
demand more distribution lines and advanced supervision systems are required. Given the need for
creating intelligent infrastructures, FANOX has developed the SIL family to carry out this function.
The SIL- A relay is designed to protect secondary transformation and distribution centers of electric
grids, using current functions. It is intended to work with a circuit breaker as cutting power element.
The protection functions can be activated by using both the front panel and the communications links to
the SICom program, allowing a precise coordination with another relay.
Additionally, all the models have been designed to be powered 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
SIL-A relays are digital based technology powered with an auxiliary voltage of 24-230 Vac/dc.
Besides the overcurrent line protection functions, instantaneous phase and neutral, with a circuit breaker
and protection against phase and neutral inverse time overcurrent, the relay provides phase imbalance
and circuit breaker fault functions as well as a thermal image protection.
As this is a line protection, a recloser is fitted. This automated control shall permit closure (up to five
attempts) with the possibility of programming each reclosing time. It can be blocked by various means,
from the HMI with a separate key to remote communications and inputs.
Further functions have been included which support line protection, such as the cold load pickup or the
trip circuit supervision.
All models include a circuit breaker management block, which:
- Monitors the condition of the circuit breaker, the number of openings and accumulated amperes.
It generates an indication when there is an excessive number of openings and accumulated
amperes.
- Determines if an opening fault has occurred
- Allows circuit breaker opening and closing commands to be given from the HMI (using different
keys) and through local and remote communications
Depending on model different functions are optional:
SILA Adaptation A: 50-1, 51-1, 50G-1, 51G-1, CLP, Second Harmonic Blocking (SHB), 49 and
86. Optionally, 52, 50BF and trip block for switch disconnector.
SILA Adaptation D: 50-1, 50-2, 51-1, 51-2, 50G-1, 50G-2, 50N-1, 50N-2, 51G-1, 51G-2, 51N-
1, 51N-2, 52, 50BF, 46, 79, 74TCS, CLP, 86, 49, Second Harmonic Blocking (SHB) and SOTF.
Optionally, 60CTS, 37, 46BC and trip block for switch disconnector
The SIL-A relay has 6 outputs that can be set by the user and 6 configurable inputs.
The relay has an LCD with two lines and twenty columns and a membrane keyboard with six buttons.
These allow the relay status, the current measurements in the primary winding and the events or
incidents associated with the relay to be seen, and adjustments to be made to the protection criteria.

www.fanox.com Rev.04 18/112
Depending on the model, these events can be saved in a non-volatile memory to keep them when there
is no power.
As well as the 6 keys to navigate the menus, there are also special keys:
•Reset. To reset the signals and events.
•79 Block/Unblock. These buttons block and unblock the recloser.
•52 I/O. These buttons serve to control the circuit breaker.
The SIL-A is fitted with 8 front LEDs, 6 of them configurable by the user.
It can store, up to 2048 events, allowing any registered incidents to be analyzed.
To facilitate the analysis of the information recorded in the relay, fault reports are also included in data
and COMTRADE format. Event recording consists of more general information, and fault reports will
record just the events related with the fault situation, allowing the user to export these fault reports in
COMTRADE format (IEEE C37.111-1991) to analyze the graphical representation of fault reports. SIL-
The relay can store the fault reports in COMTRADE format - cyclic recording by FIFO method -
(resolution 32 samples/cycle):
5 COMTRADE records (260 cycles each record): 1 to 8 pre-fault cycles + 252 to 259 postfault cycles.
25 COMTRADE records (60 cycles each record): 1 to 8 pre-fault cycles + 52 to 59 postfault cycles.
50 COMTRADE records (30 cycles each record): 1 to 8 pre-fault cycles + 22 to 29 postfault cycles.
100 COMTRADE records (15 cycles each record): 1 to 8 pre-fault cycles + 7 to 14 postfault cycles.
Current measurements are performed using the fundamental values, with an accuracy of 2% over a
range of ±20% over the nominal current and 4% over the rest of the range. Standard 5 A and 1 A current
transformers (CTs) are used depending on model.
The relay is provided with 1 front communication port. This micro USB port allows a PC to be connected
and the relay to be monitored using the SICom program in WINDOWS 7, WINDOWS 8, WINDOWS 8.1
or WINDOWS 10 (supplied by FANOX).
The rear communication ports are designed for different functions. While one is used for control,
principally including the alarm and control functions, the other is designed for specific protection
personnel consultations, with the possibility of consulting and changing, adjustment, or downloading of
events and disturbance fault recording (DFR), all without affecting the control part operation. Depending
on model, there are the following options respect to rear ports:
1. One RS485 port available in all models with selectable communication protocols
(selectable by settings) between IEC60870-103, DNP3.0 Serial and Modbus RTU.
2. One additional RJ45 port with IEC61850, DNP3.0 TCP/IP, IEC60870-104 (selectable
by settings) or Modbus TCP/IP depending on model.
Setting-up a session allows four levels of access to be set up with passwords that can be configured by
the user through SICom communication software.
The protection functions, easy-to-use interface, low amount of maintenance and simple integration make
the SIL-A a precise and practical solution to protect both industrial and public electrical grids and
transformation and distribution centres. The SIL-A protection against earthing faults is sensitive enough
to be used on electric systems with low earthing fault currents. It can be adjusted to 0.01 times the rated
current and extremely low rated levels can be selected.
The main features of the relay are listed below, and these features will be explained in the rest of the
manual:
