FOREWORD
The aim of this handbook is to provide to the User information useful for the operation of
NPM800 and NPM800R-NPM800RE 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.
This guide is the substitute of the A0343E1E. (NPM800 USER’S GUIDE)

1. Safety instructions
For your safety, we recommend you to read the following information carefully. They aim to
specify the precautions essential to the good installation and the correct operation of the
relays.
1.1 Documentation
Following documentations are available for the NP800 and NP800R:
♦ Application guide of the NP800 and NP800R series
♦ User’s Guide of Setting Software
♦ User’s Guide (for each kind of relay)
♦ First Handling Guide (for each kind of relay)
♦ Diagram of each relay
♦ Dimensions and mounting diagram
♦ Matrix choice and dimensions of ring core type C.T.
♦ User’s Guide and diagram of the BA800
We advise you to read them before any handling.
1.2 Connection of the 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 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:
- fixing rods of the current terminal blocks (NPM800)
- fixing rods of the relay case (NPM800R - NPM800RE)
♦ The good realization of connections
♦ The integrity of the connection to the earth.
1.3 On load withdrawal
With voltage or on load, it is formally misadvised to withdraw the:
- connectors and the current terminal blocks*
- relay (NPM800R - NPM800RE)
* for NPM800 relay fitted with short-circuiting devices
1.4 Removal and destruction

ICE. No duplication nor release to third

Page 6
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.

2.3 Locally available User’s functions
Locally, the following functions are available:
♦ Choice of language
♦ Setting in or out of order of the functions
♦ Customized identification of protection
♦ Setting of adjustment and primary values for the two tables
♦ Assignment of the inputs / outputs
♦ Reading of fault values

2.4 Remotely available User’s functions
The following functionalities can be accessed through the RS232 or RS485 links:
♦ Saving of configuration
♦ Commissioning tests: LCD display, adjustment of contrast, LEDs
♦ Commissioning tests: relays, wiring
♦ Reading of real time values: measurement and counters
♦ Reading of disturbance recordings.
♦ ANSI 50BF & 50_NBF circuit breaker failure function
♦ ANSI 86, latching output contacts

3. 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.
TRIP
PHASE FAULT
This message disappears at once after acknowledgement of the fault and is replaced by the
following message.
TRIP PH FAULT S
10/12 16:38.15 R
This message remains until the acknowledgement of the fault by the User.
Note: if the mode «simplified recording of events" is not chosen, the display will be as
follows:

Events are different according to information recorded when fault occurs. There are three
different types of structures of event.
They can be read with the local MMI, the setting software (RS232 link) and the Modbus
communication network.
6.1 Events generated on 50/51N/37/46 thresholds (NPM800 and NPM800R NPM800RE)
Events are recorded as soon as a trip or alarm threshold of the current functions is reached:
♦ INST PH FAULT
♦ TRIP PH FAULT
♦ INST Io FAULT
♦ TRIP Io FAULT
♦ INST UNBALA PH
♦ TRIP UNBALA PH
♦ TRIP START LON

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
The NP800 and NP800R relays are fitted with one fixing clamp to hold the network cable and
recover the shielding of the network cable:
- the network cable must be stripped
- the shielding braid of the cable must be in contact with the clamp
In order to ensure continuity of the cable and its earthing, check that the fixing clamp is
tightened on the shield recovering the jacket.

10.2 Resistance of adaptation of the RS 485 connection
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

ded to use the supplies and resistances (470 ohms) of polarization of the Master.
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.
10.3 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

10.4 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).
