FOREWORD

This aim of the handbook is to provide to the User information useful for the operation of the NPRG 860 and NPRG 870 Automatic Synchronizer devices with the local MMI, without configuration PC. It comes in complement from the First Handling Guide. We advise you to read it carefully, in order to take note of the available functionalities and to proceed to connection and power of the product in accordance with the provided recommendations. Locally, setting, commissioning and real time or event readings are accessible from keyboard and displayed on the Automatic Synchronizer device. To be fully exploited, the available functions must be parameterized and consulted with SMARTsoft, the setting software PC, provided with the product. Before any use, we recommend you to read the safety instructions of this User’s guide.

1. Safety instructions For your safety, we recommend you to read the following information carefully. They have the aim of specifying the precautions essential to the good installation and the correct operation of the products.

1.1 Documentation

Following documentations are available for the products of range NP800:

♦ General presentation of NP800 Range. ♦ Application Guide of NP800 Range. ♦ User’s Guide of the SMARTsoft Setting Software ♦ User’s Guide (by type of product) ♦ First Handling Guide (by type of product) ♦ Diagram for each relays.

We advise you to read them before any handling.

1.2 Connection of the NP800 range

The terminal blocks of the Automatic Synchronizer are studied to ensure the safety of the people during the operation of the products. During installation, commissioning or maintenance, they can however present high voltages and possibly a thermal heating. Consequently, the following precautions must be respected:

♦ Connection of the terminal blocks at installation must be carried out after having ensured of the absence of any voltage

♦ Their access during operation must be carried out through adequate means ensuring as well electric as thermal insulation

♦ The connection of the earth at the back of the relays must imperatively be done with mean of a 2.5 mm² wire.

Before powering the Automatic Synchronizer, it will be necessary to check in particular:

♦ The value of the voltage rating of the auxiliary supply and its polarization ♦ The good realization of connections

♦ Integrity of the connection to the earth.

1.3 On load withdrawal

It is formally misadvised to withdraw the connectors under voltage or on load.

1.4 Removal and destruction

The Automatic Synchronizer should in no case be opened by the User. During their removal, they must be completely isolated from any external polarity and capacitors must be discharged by connecting their external terminals to the earth. The destruction of the Automatic Synchronizer will have to be carried out in accordance with the legislation in force, in particular in compliance with the environment and safety requirements.

7.4 Connection of the Modbus RS485 communication

7.4.1 Characteristics of the network cable

Recommended characteristics for the cable:

• Shielded twisted pairs, maximum length 1000 m. • resistance < 100 ohms/km • capacity between wires < 60 pF/m • capacity between wire and shield < 100 pF/m

It is imperatively necessary to tighten the fixing clamp on the shield and not on insulator, in order to ensure continuity of the shield of the cable and its earthing.

7.4.2 Adaptation resistances of the RS 485 connecti on

In order to adapt the impedance of the RS 485 connection, two resistances of 120 ohms are necessary. With this intention, NP800 relays are fitted with a resistance of 120 ohms and a jumper provided for this purpose. To carry out this adaptation, according to the diagram below, connect the terminal «Rterm" to the terminal "- T/R» of the two end relays of the connection thanks to the jumper. The jumpers of the other relays of the connection will have to be removed

If the Master is connected at one end of the network, it is necessary to install a resistance of adaptation, not provided by ICE, then, according to the diagram below, connect the terminal «Rterm" to the terminal "- T/R» of the end relay of the connection thanks to the jumper. The jumpers of the other relays of the connection will have to be removed.

7.4.3 Polarization of the RS 485 connection

Polarization having to be single on a line to prevent the risks of transmission, it is in this case recommended to use the supplies and resistances (470 ohms) of polarization of the Master.

7.4.4 RS 485 connection not used

If the communication is not used, it is necessary to connect the terminal «Rterm" to the terminal "- T/R» of the relay thanks to the jumper(s) fitted for this purpose (RS485-1 and RS485-2).
