Installation and use restrictions
(Applicable in the European Union and other European countries with separate
collection systems). This marking on the product, accessories or literature
indicates that the product should not be disposed of with other household
waste at the end of their working life. To prevent possible harm to the
environment or human health from uncontrolled waste disposal, please
separate these items from other types of waste and recycle them responsibly to promote
the sustainable reuse of material resources. Household users should contact either the
retailer where they purchased this product, or their local government office, for details of
where and how they can take these items for environmentally safe recycling. This product
and its electronic accessories should not be mixed with other commercial wastes for
disposal.
Iono Pi contains a small non rechargeable manganese dioxide lithium coin battery. This
cell battery contain so little lithium that it should not qualify as a reactive hazardous waste.
If you need to follow specific disposal procedures for the battery, it can be easily separated
from the circuit board by simply cutting its two terminals near the soldering points (paying
attention not to pinch or fracture the battery body).
Standards and regulations
The design and the setting up of electrical systems must be performed according to the
relevant standards, guidelines, specifications and regulations of the relevant country. The
installation, configuration and programming of the devices must be carried out by trained
personnel. The installation and wiring of connected devices must be performed according
to the recommendations of the manufacturers (reported on the specific data sheet of the
product) and according to the applicable standards. All the relevant safety regulations, e.g.
accident prevention regulations, law on technical work equipment, must also be observed.
Safety instructions
Protect the unit against moisture, dirt and any kind of damage during transport, storage
and operation. Do not operate the unit outside the specified technical data. Never open the
housing. If not otherwise specified, install in closed housing (e.g. distribution cabinet).
Earth the unit at the terminals provided, if existing, for this purpose. Do not obstruct cooling
of the units. Keep out of the reach of children.
Set-up
For the first installation of the device proceed according to the following procedure:
✓make sure all connections, including the power supply and any other external devices
are disconnected
✓install and wire the device according to the schematic diagrams on the specific data
sheet of the product
✓after completing the previous steps, switch on the power supply and other related
circuits.

Standards
✓2014/35/UE (Low Voltage)
✓2014/30/UE (EMC)
✓EN61000-6-2:2005 (EMC Immunity)
✓EN60664-1:2007 (Electrical safety)
✓EN61000-6-3:2007 (Emission)
✓2011/65/UE (RoHS).
WiFi and Bluetooth must be disabled on the Raspberry Pi 3 to meet the above CE
directives.
Hardware Installation
The Iono Pi board is supplied with all connectors pre-installed. No soldering is required.
You should connect Iono Pi to Raspberry Pi aligning the GPIO connector. Use appropriate
turrets/spacers to firmly bolt the two boards together, ensuring that no conductive part of
one board touches any part of the other board.
Be particularly careful to ensure there is enough clearance between the Ethernet and USB
connectors and the bottom of Iono Pi’s circuit board.
The Iono Pi board is compatible with Raspberry Pi 2 Model%B and Raspberry Pi 3 Model%B.
Installing boards that are not fully compatible, both mechanically or electrically, may and
probably will damage both Iono Pi and any other component connected to it, and may
create a safety risk.
The factory warranty does not cover any damage directly or indirectly caused by the
installation and removal of the Iono Pi board and Raspberry Pi.
Terminal block
Iono Pi has two terminal blocks: a 15 positions terminal block, used for power supply and
low-power input/output connections, and a 8 positions terminal block on the opposite side,
for the power relays outputs.
Power supply
Iono Pi can be powered with DC voltage only:
✓DC: nominal voltage range 9.0V to 28.0V.
Respect the correct polarity shown in the schematic diagram (+ -).
A blue on-board LED, also visible through the front panel of the DIN-rail case, is lit when
power supply is available.
When a Iono Pi board is used, never connect the Raspberry Pi micro-USB power plug.
Read the Iono Pi User Guide for detailed installation and use information related to the
auxiliary power supply output (VSOUT and 5VOUT).
