this reason only qualified personnel may work on or operate the equipment.
Qualified personnel are individuals who:
• Have read and understood the information on the device and its user manual.
• Are familiar with the installation, commissioning, and operation of the equipment and of the
system to which it is being connected.
•Are able to safely perform switching operations in accordance with accepted safety engineering
practices and are authorized to energize and de-energize equipment and to isolate, ground,
and label it.
•Are trained in the care and use of safety apparatus in accordance with safety engineering

• Before removing the enclosure, the operator must be equipotential with the equipment.
• Avoid touching the electronic. The board must be always manipulated for the edges.
• If the equipment has to be passed between two persons, both must be equipotential.
• Put the module always on an antistatic surface or on a surface equipotential with you.
• During the storage and transport, the module will remain in the packaging.
Not following these instructions can give like result that the device do not work properly
or even can damage to the people or devices.
1.7 Technical Specifications for Safety
1.7.1 Protective Elements

2.1 Saitel DR Platform
Saitel DR is a hardware platform by Schneider Electric. It consists of a set of equipment which
have been specifically designed for real-time control and automation applications. Saitel DR is a
high-technology platform which serves Schneider Electric’s business areas.
On this hardware platform, the Baseline Software Platform is installed. This software is used in
Saitel families (Saitel DP and Saitel DR) and other Schneider Electric products.
Other features identifying Saitel DR are:
• A DIN rail is used for the mechanical installation.
• The communication between the controls units integrated in a distributed system is mainly
established by Ethernet.
•The terminal blocks for field-connection are completely built into acquisition blocks.
Figure 6 - Saitel DR.
Saitel DR’s design has been optimized to meet the most demanding requirements of multiple
sectors:
•Safety and reliability requirements for power, gas and water supply, as well as sewage
treatment plants, etc.
• Compliance with electric safety, electromagnetic compatibility, and environmental standards.
• Centralized monitoring and control of geographically-distributed systems which support
hierarchical data acquisition and sharing networks.
• Local monitoring and control with data sharing capabilities of plant-distributed equipments.
• Quick troubleshooting, including the possibility of using programmable automation execution.
operation.
2.2 AB_AC Functions
The AB_AC module is used for magnitudes measurements in alternating current networks and for
energy measurements. This module performs, as well, other typical functions in transmission and
distribution networks, for instance, synchronism checking between two power lines
(Synchrocheck).
The diagram below illustrates the functional block diagram:
Figure 7 - Functional block diagram.
User Manual – AB_AC
07/05/2020
R&D Digital Seville
Page 19
WARNING
If a calibration is performed on the channels, the factory calibration will be deleted.
Power Supply
The AB_AC module receives its power supply through the CAN communications bus.
Through this general power supply, the polarization is supplied internally to the digital inputs and
outputs.
The AB_AC module has a consumption of 2 W at 25 ºC.
Digital Input and Output
The direct measurement module integrates a digital input and a digital output with the adequate
protection elements.
Currently, these two signals are reserved for Synchrocheck aplication, so if this functionality is not
selected, neither the input or the output should be wired.
Analog Inputs
The AB_AC module allows connecting:
• 3 independent voltage inputs.
• 3 independent current inputs.
• An additional input for the neutral current line.
All signals are connected usin 2-wire connectors.
The system allows processing signals for a nominal frequency of 50 or 60Hz. The user can select
the frequency using Easergy Builder.
Each channel is protected separately against electromagnetic disturbances.
The user can calibrate these channels using the console connection available in all HU types and
Saitel Webtool (only advanced HUs).
Field Signals Adaptation Block
This block contains all the required elements to adapt the field signals to the value ranges used by
this processing unit. It also provides the required protection elements for the galvanic isolation of
each channel.
Technical data for A1 ordering options are specified in chapter “5 Technical Specification Table”.
Other values are available, upon request.

User Manual – AB_AC
Page 20
R&D Digital Seville
Processing Block
The processing block filters the analog signals coming from the adaptation block and, then, it
digitalizes them at a 6.4 kHz frequency (for a 50Hz electric line frequency) and at a 7.68 kHz
frequency (for a 60 Hz electric line frequency).
Control Block
This block manages the communications through the internal bus, as well as the storage of the
module´s calibration parameters.
2.3 Interfaces
Following interfaces are available in this module:
• 1 removable terminal block to connect three voltage inputs.
• 1 removable terminal block to connect one digital output.
• 1 removable terminal block to connect one digital input.
• 1 screw terminal block to connect three current inputs and one neutral (homopolar) current.
• 8 LED indicators.

Section 3.3 provides detailed information about the operation of each LED.
Voltage Inputs (B1) and Current (B4) Inputs
Both voltage and current inputs are connected to the module by means of screw terminals. The B1
terminal block includes six terminals: two for each voltage input whereas the B4 terminal block
includes eight terminals: two for each phase current and the remaining two for the neutral current
Digital Input and Output (B2 and B3)
• The digital output is a voltage free contact.
• The digital input is only for syncrocheck applications and must be polarized with 24 V.
These terminal blocks are only used with Synchrocheck. There are several options to wire them to
signals. Project’s engineers should analyze each option to apply the best solution, according the
advantages and disadvantages of each option.
