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.
