INSTALLATION
•Installation work must only be carried out by a
competent person under qualified supervision.
•A fused isolation switch must be fitted between
the main power supply and the X8I or X12I.
•The X8I or X12I should be mounted in such a
location as to allow operational and maintenance
access without obstruction or hazard and to
allow clear visibility of indicators at all times.
•If raised platforms are required to provide access
to the X8I or X12I they must not interfere with
normal operation or obstruct access. Platforms
and stairs should be of grid or plate construction
with safety rails on all open sides.
instructions. If you have any questions regarding the X8I
or X12I, please contact your local authorized and trained
Ingersoll Rand Service Center or contact Technical
Support Services at 800-820-0308 to speak one of our
Technical Support Engineers.
OPERATION
•The X8I or X12I must only be operated by
competent personnel under qualified
supervision.
•Never remove or tamper with safety devices,
guards or insulation materials fitted to the X8I or
X12I.
•The X8I or X12I must only be operated at the
supply voltage and frequency for which it is
designed.
•When main power is switched on, lethal voltages
are present in the electrical circuits and extreme
caution must be exercised whenever it is
necessary to carry out any work on the unit.
•Do not open access panels or touch electrical
components while voltage is applied unless it is
necessary for measurements, tests or
adjustments. Such work should be carried out
only by a qualified electrician equipped with the
correct tools and wearing appropriate protection
against electrical hazards.
•All air compressors and/or other equipment
connected to the unit should have a warning sign
attached stating ‘THIS UNIT MAY START
WITHOUT WARNING' next to the display panel.
•If an air compressor and/or other equipment
connected to the unit is to be started remotely,
attach warning signs to the equipment stating
‘THIS UNIT CAN BE STARTED REMOTELY’ in a
prominent location, one on the outside of the
equipment, the other inside the equipment
control compartment.
MAINTENANCE AND REPAIR
•Maintenance, repairs or modifications must only
be carried out by competent personnel under
qualified supervision.
•If replacement parts are required use only
genuine parts from the original equipment
manufacturer, or an alternative approved source.
•Carry out the following operations before
opening or removing any access panels or
carrying out any work on the X8I or X12I:
•Isolate the X8I or X12I from the main electrical
power supply. Lock the isolator in the 'OFF'
position and remove the fuses.
2
•Attach a label to the isolator switch and to the
unit stating ‘WORK IN PROGRESS - DO NOT APPLY
VOLTAGE'. Do not switch on electrical power or
attempt to start the X8I or X12I if such a warning
label is attached.
•Make sure that all instructions concerning
operation and maintenance are strictly followed
and that the complete unit, with all accessories
and safety devices, is kept in good working
order.
•The accuracy of sensor devices must be checked
on a regular basis. They must be calibrated when
acceptable tolerances are exceeded. Always
ensure any pressure within the compressed air
system is safely vented to atmosphere before
attempting to remove or install a sensor device.
•The X8I or X12I must only be cleaned with a
damp cloth, using mild detergents if necessary.
Avoid the use of any substances containing
corrosive acids or alkalis.
•Do not paint the control faceplate or obscure any
indicators, controls, instructions or warnings.

CHECK LIST GUIDANCE
oElectrical Drawing For Each Compressor: It is
important to have the Electrical drawing for each
compressor so that the correct interconnect
drawing can be referenced from the Interconnect
and Application Guide
oTypes of Compressors To Be Sequenced: Refer
to the Interconnect and Application Guide for
specific details on the types of compressors that
can be sequenced and their individual
requirements such as Auto Restart, Intellisys
Software, etc.
oir-PCB and ir-485 and/or irV-485 Gateway
Mounting: The ir-PCB and the Gateway module
is designed to be installed within the compressor
starter enclosure. The mounting location of the
ir-PCB should be away from any high voltage
connections, contactors, or transformers.
oir-PCB, ir-485 and/or irV-485 Gateway and
Compressor Interconnections: Refer to the
Interconnect and Application Guide for specific
drawings for various compressors and the X8I or
X12I. If there is not a specific drawing available
for the compressor being sequenced at the site,
please contact Technical Support Services for
assistance.
oir-PCB, ir-485 and/or irV-485 Gateway and
Compressor Interconnection Wire: The X8I or
X12I Installation kit contains 330 Ft (100m) of 18
gauge stranded wire (Orange) to use for the
connections between the ir-PCB and the
compressor. In most cases, this is sufficient for
most installations. If additional wire is required,
any 18 gauge stranded wire can be used in lieu
of the wire provided in the kit.
X8I or X12I Installation kit also contains an
interconnect cable for the connection between
the ir-485 Gateway and the Intellisys Controller.

485 and/or irV-485 Gateway or any Optional
Integration Boxes is Belden 9841 (or equivalent).
It should be run in grounded conduit and should
not be greater than 4000 feet (1219 meters) in
length (The exception to this is connecting the

oAll external wiring to the X8I or X12I should be
made through the holes (grommets are provided)
in the X8I or X12I enclosure (8 in total). Drilling
or tapping additional holes in the enclosure can
result metal shavings making contact with the
circuit boards. Damage due to metal shavings in
the circuit boards is not covered by warranty.
oPower / Local Disconnect (Breaker): Incoming
power (115VAC/230VAC, single phase) should
be fused (100VA) and a local disconnect
provided. The power source should be regulated
and noise free. The use of a power supply
regulator might be required in applications
where unregulated power is an issue
oConfirm that all electrical connections are made
properly and tightened and conform to local
standards.
oCommon Receiver: The X8I or X12I must have
its pressure transducer located in a common
receiver for proper Wet Side or Dry Side System
pressure control.
