The Ex-certified version of this product (ASM0627-09-N-Cx-O-Gx-D3x) was assessed against
the following standards for hazardous environments:
IEC60079-0 Explosive Atmospheres –Equipment General Requirements
IEC60079-1 Explosive Atmospheres –Equipment protection by flameproof enclosures
IEC60079-26 Explosive Atmospheres –Equipment with EPL Ga
In addition, IEC60079-28 Explosive Atmospheres –Protection of equipment using optical
radiation was considered but the equipment is not in the scope of this standard because (ref
section 1, part 5) it has an enclosure that fully contains the optical radiation and provides IP6X
protection in accordance with IEC60529 Degrees of protection provided by enclosures (IP
code).
Furthermore, elements of IEC60079-31 Explosive Atmospheres –Equipment dust ignition
protection by enclosure have been applied to preclude optical absorbers from entering the
probe.
In accordance with IEC60079-26, the rigid dip probe achieves EPL Ga and can be inserted
into zone 0 environments while the main instrument achieves EPL Gb for use in zone 1. The
user should be aware that creating an opening in a zone 0 environment may lead to the release
of flammable gas and flame entrance. EPL Ga is achieved for the dip probe since it is an
enclosure providing protection against dust ignition.

2. HOW TO POWER AND CONNECT THE IRmadilloNA
2.1. Powering the IRmadilloNA
NOTE
REMARQUE
See Section 1 Safety prior to attempting installation.
Reportez-vous à la section 1 Safety avant de procéder à
l’installation.
The spectrometer is normally supplied with a blunt-cut mains cable to be wired into your
electrical supply. The instrument requires single-phase mains input and must be connected to
a permanent earth (grounding) connection. A 5A fuse should be fitted in the live/hot supply
connection.
The power supply needs to be fitted with a means of isolating both live and neutral by fitting a
disconnecting switch or using a suitable circuit breaker that meets the requirements of IEC
60947-1 and IEC 60947-3. The switch must be located within easy reach of the instrument
and must be marked as the disconnection device for the equipment. The disconnection device
must not interrupt the earth connection.
The spectrometer is designed to operate over a wide range of voltages shown below in Table
2 - IRmadilloNA power specifications. If you plan to operate the spectrometer outside of
these ranges, contact Keit for advice before powering up the instrument.

2.1.1. Uninterruptible power supply (UPS)
To ensure a reliable supply of power to the IRmadilloNA, we strongly recommend use of an
uninterruptible power supply (UPS). Contact support@keit.co.uk for further information.
If you are unable to use a UPS, you may find that the system fails to start correctly following
a power cut. In this situation, Keit recommends power cycling first the IRmadilloNA and then
the controller.
2.1.2. Power cable
The power cable for the IRmadilloNA is a permanently connected flying lead passed through
a cable gland; this is located at the rear of the spectrometer. The gland and cable must be
sufficiently protected from loading and twisting. The cable should ideally be routed above
ground to avoid accidental damage.
Page 9
DOC1048R (21 December 2023 17:31)
www.keit.co.uk Back to Table of Contents
Figure 1: Power and communication gland locations
The spectrometer body has an optional external M6 earth attachment point below the probe.
This can be used where local codes require it. The internal earth bonding through the power
supply cable is the primary earth and the external is optional. Please identify and adhere to
any applicable local standards.
WARNING
AVERTISSEMENT
Failure to properly earth the spectrometer may cause
serious injury or death.
Une mise à la terre incorrecte du spectromètre peut causer des
blessures graves, voire la mort.

2.2. How to connect data communications
Like the power cable, the IRmadilloNA is supplied with a permanently connected flying lead
for communication that is passed through a cable gland. You must ensure that the cables are
sufficiently protected from loading and twisting. The cable should ideally be routed above
ground to avoid accidental damage.
NOTE
REMARQUE
Ensure the mains and data communication cable connectors
are dry prior to mating.
Assurez-vous que les connecteurs du câble d’alimentation et de
celui de communication des données sont secs avant de les
brancher.
NOTE
REMARQUE
Keep the dust caps fitted on connectors when not in use.
Never leave an exposed connector.
Maintenez les bouchons antipoussière installés sur les
connecteurs lorsqu’ils ne sont pas utilisés. Ne laissez jamais un
connecteur exposé.
Model numbers of the form ASM0627-09-N-Cx-O-G-xx have the Hawke FibreEx in-line
connector for use in explosive atmospheres. The flying lead from the IRmadilloNA mates with
the supplied extension cable.
2.2.1. Connecting the Hawke FibreEx in-line connector
•Unscrew the cap on the end of the connector.
•Align the key on the connector with the keyways in the corresponding connector
•Mate the two connectors together
•Rotate the shell secure and complete the connection
•Check that the green and orange lights on the controller are present (Figure 5)

The extension cable is terminated with a Souriau UTS-LC in-line plug.
Figure 4 Souriau in-line plug
2.2.2. Connecting the fibre data communication cable to the controller
•Remove the dust cap from the data communication cable.
•Carefully match up the data communication cable with the corresponding port on the
back of the controller.
•Tighten the locking nut. This will make a secure connection.
•Check that the green and orange lights on the controller are present (see image).
Figure 5: Front panel of Keit controller
NOTE
REMARQUE
Protect the data communication fibre from stress and tight
bends (< 80mm bend radius not allowed!). Tight bends cause
a stress at the glass surface and increase the probability of
fracture.
Protégez la fibre de communication de données des contraintes et
des courbures serrées (rayon de courbure < 80 mm interdit!). Les
courbures serrées provoquent des contraintes à la surface du
verre et augmentent la probabilité de fracture.
2.3. Installation best practice
Having cleaned the probe and taken a background spectrum, the IRmadilloNA is ready to be
inserted into the reaction/process of interest.
Probe installation is unique for each application. Safe installation of the probe into the process
is the responsibility of the user and should be assessed by a suitably trained person.
Please refer to the interface drawings of your probe and mounting system for further guidance.
To ensure success with installs, it is important to consider the following requirements:
Page 12
DOC1048R (21 December 2023 17:31)
www.keit.co.uk Back to Table of Contents
•The IRmadilloNA needs to be suitably supported. The weight of the instrument is ~18
kg, and it must be supported using the mounting points at the base, either through a
custom stand or using a Keit Cradle. The probe should not be used to support the
instrument.
•The body of the IRmadilloNA should not be placed in direct sunlight or near a heat
source. The instrument has internal temperature control, but this rating is limited and
model dependant. Direct heat sources can force the instrument beyond its operating
range and cause damage.
•The IRmadilloNA must be axially restrained when in the flow. Pressure on the probe
will cause the system to move if not properly restrained along the probe’s axis.
Figure 6: Probe immersion depth in pipework
•The central axis of the probe must be in line with the centre of the pipework.
•The probe must be aligned correctly with the port in which it is placed. It should not be
forced or bent into place as this will cause damage to the instrument.
•The nominal position of the probe end from the internal pipe wall is 10 ± 5 mm.
•The IRmadilloNA must be exposed to the flow when in operation. The probe tip must
be positioned in the flow within the pipeline or vessel to perform correctly; turbulent
flow is desired. If the tip is held in stagnant chemistry, building representative
chemometric models will not be possible.
•It is preferable to mount the IRmadilloNA with the probe positioned horizontally.
Mounting the IRmadilloNA with the probe pointing downwards risks the formation of
bubbles on the ATR element, and prevents the ATR from coming into full contact with
the analyte to correctly analyse the process liquid.
•Similarly, avoid mounting the IRmadilloNA with the probe pointing upwards. If there
are any suspended solids in the mixture, there is a risk of these solids settling on the
probe tip, which may result in the spectra not being representative of the process liquid.

5.1.2. Installation
The sealing face on the probe requires a gasket to mate against the flange on the process
pipework. The gasket material must be chosen to be compatible with the pressure and
temperature range of the process media and must be chemically compatible.
WARNING
AVERTISSEMENT
Choice of gasket material must be appropriate for the
chemistry and process being used.
Le matériau du joint choisi doit être approprié pour le produit
chimique et le processus utilisés.
The probe body and hub are manufactured from Hastelloy as standard, which is resistant to
many aggressive chemicals. However, you are advised to check with Keit before
installing on a new process.
Before beginning installation, ensure that the gasket is in good condition and that the sealing
faces are not scratched or dented.
Support the spectrometer on a suitable mounting frame that aligns the probe with the flange
port that it will be fitted to. Avoid applying stress to the probe, weld, or flange by ensuring that
the sealing face of the hub sits flush against the gasket and sealing face of the mating flange
before fitting any mounting bolts to the flange.
