PREFACE
This aim of this handbook is to provide to the User information useful for the operation of
NPI800 and NPID800 relays with the local MMI.
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 protection display.
To be fully exploited, the available functions must be parameterized and consulted with the
setting software PC – Protection, provided with the product.
Before any use, we recommend you to read the safety instructions of this User’s guide.

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 relays.
1.1 Documentation
Following documentations are available for the products of the range NP800:
♦ General Presentation of the NP800 range
♦ User’s Guide of Setting Software for NP800 range
♦ User’s Guide (for each kind of relay)
♦ First Handling Guide (for each kind of relay)
♦ Diagram of each relay.
We advise you to read them before any handling.
1.2 Connection of NP800 relays
The terminal blocks of the relays are studied to ensure the safety of the people during the
operation of the relays.
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 relays, it will be necessary to check in particular:
♦ The value of the voltage rating of the auxiliary supply and its polarization
♦ The tightening of the intensity circuits and the good realization of connections
♦ The integrity of the connection to the earth.
1.3
On load withdrawal
It is formally misadvised to withdraw the connectors, in particular the current terminal blocks,
under voltage or on load.
1.4 Removal and destruction
The relays should in no case be opened by the User. During their removal, they must be
completely isolated from any external polarity and condensers must be discharged by
connecting their external terminals to the earth.
Destruction of the relays will have to be carried out in accordance with legislation in force, in
particular in compliance with the environment and safety requirements.

First use
When powering the relay, the displays below can appear. The recommended action allows
starting the parameter setting of protection.
3.1
Default screen
In absence of a fault, the protection displays the phase 1 current measurement in HV value.
CURRENT I1
0.0 A
3.2
Presence of a fault or an alarm
If a fault or alarm occurs, a message indicates the type of fault.
When threshold is exceeded or when tripping, the following messages appear:
INSTANT. PHASE
THRESHOLD
Followed
by

Note: According to the type of fault, the message of the second line changes.
This message disappears at once after acknowledgement of the fault and is replaced by the
following message.

Connection of the current inputs
Connection is done by 6mm² ring terminals for M4 screw. It is identical for all the variants of
inputs:
♦ Phases CT 1A or 5A
♦ Earth-fault CT 1A or 5A or CT Ring.
Respect the rotating sense of phases and the direction of the connection of phases.

Connection of the Modbus RS485 communication
8.5.1 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.
8.5.2 Resistance of adaptation
Connect a 120 ohms resistance of adaptation to each protection located at each end of the
network.
It is necessary to connect the Rterm +T/R according to the diagram
RS485

If the Master is connected at one end of the network, it is necessary to place a resistance of
adaptation on the Master and another on the protection located at the other end of line using
the switches of the communication board.
