2.2 UNPACKING
The shipping container includes:
-the IPR96D Relay
-this instruction manual
-the fixing elements
-the Test Report (if required)
Inspect the unit and inform ORION ITALIA of any damage.
If reshipment is required, the original container and packing should be used.
2.3 MOUNTING
The mounting should be carried out as follows:
1. Install the relay in a place where the humidity and temperature are those for which it has been designed [General Information:
1.8 SPECIFICATIONS] and away from high current conductors and sources of strong magnetic fields.
2. Put the relay on a panel so that the keypad is easily accessible, and the display is visible.
3. Make a cutout in the panelboard [Figure 2.1] and fix the relay by using the fixing elements provided.

Before carrying out the installation of the unit, it is necessary to read and understand the indications provided by the
Constructor. All the installation operations must be carried out by qualified personnel with adequate knowledge of the
functioning of the unit and of the content of this manual.
The control power, current/voltage input and output contacts must be connected according to the supply voltage connection
diagram included in the present manual. Ensure applied currents/voltages abide by the IPR96D ratings indicated on the relay
label.
Orion Italia suggests that the maximum length of the digital input connections must be under 3mt.

2.5 COMMUNICATIONS
Thanks to the serial port the monitoring and control of the relay can be made by a SCADA system, a PC or PLC device.
The ports provided are:
1 two-wire RS-485 port
→
1 twisted pair which transmits and receives alternatively is used for the data
TX and RX
For the RS-485 port use shielded & twisted pair wire to minimize communication errors from noise.
A suitable type of wire is: BELDEN#9841, AWG 24 which is shielded and with a characteristic impedance of 120 .
Ground the shield only at one point [Figure 2.4]
For the RS-485 port a maximum of 35 relays can be daisy chained together in parallel mode on a communication channel for a
MAXIMUM DISTANCE OF 1000 METERS.
For larger systems, additional RS-485 channels must be added.
To increase the number of relays over 35 on single channel, consult the relay constructor.
2.6 POWER SUPPLY
Voltage ranges for the relay →[General Information: 1.8 SPECIFICATIONS]
Power supply connection terminals →[Installation: 2.3 WIRING]
The relay has no internal fuses, external protection should be applied.
Orion Italia advices the use of 1 A timed external fuse.

No digit in the resulting password can equal zero (0). If the sum of the two digits is greater
than ten (10), only the unit will be considered. If the sum equals ten (10), the digit will become
one (1).
For example: PSW1 = 9896 (new user password)
PSW1 = 1111 (factory default)

will be opened. In case of fault of the relay (STATUS led “On”) or of loss of power
supply, AUX2 will pass to safe state position and exchange its contacts.
If the fault disappears, the IPR96D will get back to normal operation; the Out of
Service relay will remain latched in safe state position (local HMI reset required).

IPR96D Ground Protection Relay 6.2 Instruction Manual: IPR96D GBM 24/11/2020
System Setup
Max Switching Current
Value ENABLED
RANGE: ENABLED; DISABLED
Indicate whether you want to enable or disable a current limit beyond which the
relay must not activate the TRIP output to avoid damaging the switching device
(useful when there is a switch/disconnector instead of a Circuit Breaker). In case
of Circuit Breaker, make sure to select DISABLED.
System Setup
Max Switching Current
Value 400 A
RANGE: 50 5000
STEPS: 10
The selected value indicates the current limit described in the screen above.
[6.2 Setpoints: SYSTEM SETUP]
If Max Switching Current = ENABLED
System Setup
Breaker Failure Relay
Value - - -
It allows selecting the output signaling the discrepancy between the trip command
sent by the protection relay and the signal received at the BREAKER STATUS
input from the circuit breaker or disconnector auxiliary contact.
This error information signals that the trip command has not provoked the opening
or that the auxiliary contact (52a) does not operate properly.
Disable this function in case of no connection between 52a auxiliary contact and
BREAKER STATUS input.
To disable the function, select "- - - ".
System Setup
Breaker Failure Delay
Value 1000 ms
RANGE: 10 2500
STEPS: 10
Delay for the circuit breaker auxiliary contacts to signal the opening. If a correct
reply is not obtained in this delay, an event for circuit breaker failure will be
displayed and the selected contact will activate.
[6.2 Setpoints: SYSTEM SETUP]
If Breaker Failure Relay ≠- - -
System Setup
Mech. Operations
Relay
Value - - -
Select the relays to be activated when reaching the max. number of mechanical
operations set in the next Line.
System Setup
Mech. Operations
Max
Value 3000
RANGE: 5 9995
STEPS: 5
This value represents the granted quantity of mechanical operations carried out
by the circuit breaker and the event indicates that maintenance is required.

Press ENTER to modify.
Following the intervention of the Breaker Failure function, once the circuit breaker has been repaired, it will be necessary to
reset the IPR96D (if still in Tripped state) before proceeding to close the circuit breaker.
