Safety instructions
Safety symbols and messages
Read these instructions carefully and look at the equipment to become familiar with
the device before trying to install, operate, service or maintain it. The following
special messages may appear throughout this bulletin or on the equipment to warn
of potential hazards or to call attention to information that clarifies or simplifies a
procedure.
Risk of electric shock
The addition of either symbol to a “Danger” or “Warning” safety label on a device
indicates that an electrical hazard exists, which will result in death or personal injury
if the instructions are not followed.
ANSI symbol
IEC symbol
.
Safety alert
This is the safety alert symbol. It is used to alert you to potential personal injury
hazards and prompt you to consult the manual. Obey all safety instructions that
follow this symbol in the manual to avoid possible injury or death.
Safety messages
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided,
will result in death, serious injury or property damage.
4
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided,
could result in
death, serious injury or property damage.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided,
minor or moderate injury or property damage.
Important notes
Restricted liability
Electrical equipment should be serviced and maintained only by qualified personnel.
No responsibility is assumed by Schneider Electric for any consequences arising out
of the use of this manual. This document is not intended as an instruction manual for
untrained persons.
Device operation
The user is responsible for checking that the rated characteristics of the device are
suitable for its application. The user is responsible for reading and following the
device’s operating and installation instructions before attempting to commission or
maintain it. Failure to follow these instructions can affect device operation and
constitute a hazard for people and property.
Protective grounding
The user is responsible for compliance with all the existing international and national
electrical codes concerning protective grounding of any device.

General
IEC 60870-5-103 communication enables Sepam series 20, Sepam series 40 and
Sepam series 80 units to be connected to a supervisor or other device featuring an
IEC 60870-5-103 communication channel.
Communication is based on the master/slave principle:
b Sepam is always a slave station.
b The master is the supervisor or another device.
IEC 60870-5-103 communication is available via the ACE969 communication
interface.
ACE969TP communication interface.
ACE969 is a multiprotocol communication interface with two independent
communication ports:
b The S-LAN (Supervisory-Local Area Network) port is used to connect Sepam to a
communication network dedicated to supervision.
b The E-LAN (Engineering-Local Area Network) port is reserved for specific Sepam
setup, operating and adjustment functions. This port is connected to the SFT2841
software tool.
The ACE969 interface is available in two versions, linked to the physical interface of
the S-LAN supervision port:
b ACE969TP (Twisted Pair) for an S-LAN network, 2-wire RS 485 serial link
b ACE969FO (Fiber Optic) for a fiber-optic star or ring S-LAN
The E-LAN engineering port is always a 2-wire RS 485 type port.
ACE969FO communication interface.
SFT2841
Accessible data
IEC 60870-5-103 communication via the S-LAN port provides access to a great deal
of information, in particular:
b Reading of metering information
b Reading of status conditions and time-tagged events
b Transfer of files including disturbance records and tripping contexts
b Time-setting and synchronization
b Transmission of remote controls
Sepam series 20
S-LAN
E-LAN
ACE969
The actual list depends on the application, the type of Sepam, the enabled functions,
and the ACE969 interface parameter settings.
Sepam series 40
Connecting the SFT2841 tool to the E-LAN port also provides access to all Sepam
function parameters and operating data:
b Hardware configuration parameters
b Remote settings for protection functions
b Switching on/off of protection functions
b Retrieval of disturbance records
b Display of metering and diagnosis information
b Display of logic states
b Display of alarms

S-LAN: IEC 60870-5-103 supervision
E-LAN: For SFT2841 operating functions.

Presentation
The IEC 60870-5-103 protocol is a companion standard for the informative
interface of protection equipment.
Standard IEC 60870-5-103 was prepared by IEC technical committee 57 (Power
system control and associated communications).
It is a companion standard for the basic standards in series IEC 60870-5.
