SECTION 2 — INTRODUCTION
The X4I is a specialized controller designed to provide
safe, reliable, and energy-efficient control of your
compressed air system. The X4I is capable of controlling
up to four positive displacement air compressors. The
compressors may have electro-pneumatic or
microprocessor based controls. The X4I is completely
customizable to meet the specific needs of your
compressed air system.

• Before installing or operating the X4I,
take time to carefully read all the
instructions contained in this manual, all
compressor manuals, and all manuals of
any other peripheral devices that may be
installed or connected to the unit.
• Electricity and compressed air have the
potential to cause severe personal injury
or property damage.
• The operator should use common sense
and good working practices while
operating and maintaining this system.
All applicable codes should be strictly
adhered to.
• Maintenance must be performed by
adequately qualified personnel that are
equipped with the proper tools.
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
X4I.
• The X4I 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 X4I, 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.
OPERATION
• The X4I must only be operated by
competent personnel under qualified
supervision.
• Never remove or tamper with safety
devices, guards or insulation materials
fitted to the X4I.
• The X4I 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 two warning
signs to the equipment stating “THIS
UNIT CAN BE STARTED REMOTELY”.
Attach one sign in a prominent location
on the outside of the equipment, and
the other sign 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.
