“WARNING” refers to situations that could result in personal injury.

“CAUTION” refers to situations that could result in equipment damage.

Failure to follow the requirements below may lead to dangerous situations.

FR:

«AVERTISSEMENT» fait référence à des situations pouvant entraîner des

blessures corporelles.

«ATTENTION» fait référence à des situations pouvant entraîner des dommages

matériels.

Le non-respect des exigences ci-dessous peut conduire à des situations

dangereuses.

If the equipment is used in a manner not specified by Keit, the protection provided by the

equipment may be impaired.

This manual is intended to be read in conjunction with DOC1049R which describes non-safety

aspects of using the IRmadilloNA.

1.1. General safety

WARNING

AVERTISSEMENT

The spectrometer weighs ~18 kg; handle with care

Le spectrometer pèse environ 18 kg; manipulez-le avec soin

CAUTION

MISE EN GARDE

analyte conditions specified on the product label

N’utilisez pas l’équipement hors des conditions

environnementales ou d’analyte spécifiées dans la plaque

signalétique

CAUTION

MISE EN GARDE

The probe is NOT a carry handle

1.3. Electrical safety

WARNING

AVERTISSEMENT

The electrical mains cable must be earthed and should

include a 5A fuse with a means of isolating both live and

neutral; obey local electrical safety codes

Le câble d’alimentation électrique doit être mis à la terre et doit

comporter un fusible de 5 A avec un moyen d’isoler la phase et

le neutre ; respectez les codes de sécurité électrique locaux.

WARNING

AVERTISSEMENT

An additional earth connection is provided on the

enclosure chassis using an M6 screw; use if required by

local codes

Une mise à la terre supplémentaire est fournie sur le châssis

de l’enceinte au moyen d’une vis M6 ; utilisez-la si cela est

requis par les codes locaux.

WARNING

AVERTISSEMENT

Never disconnect the mains power connector when

energised

Ne débranchez jamais le connecteur d’alimentation réseau

lorsqu’il est branché.

CAUTION

MISE EN GARDE

Residual current protection or ground fault interrupter

devices are recommended

L’installation d’une protection contre le courant résiduel ou d’un

interrupteur de défaut de terre est recommandée.

1.4. Pressure and temperature limits

The maximum pressure and temperature (ambient and analyte) limits for the device vary

depending on the model and mechanical interface. Refer to the product label to confirm the

limits.

Do not exceed the pressure limits on the product label as this could be dangerous and will

invalidate the warranty. If in doubt, contact Keit for advice before installing the spectrometer.

When purging the instrument, the maximum total flow rate of the purge gas is 3 liters/minute.

1.5. Operating environment limits

The spectrometer is thermally stabilised and designed to operate indoors or outdoors under a

variety of conditions and environments. Avoiding exposure to direct sunlight will help maintain

this thermal stability.

Pollution degree of the environment refers to the level of contamination that the exterior of the

device can cope with. Pollution degree 4 means that continuous conductivity from conductive

dust, rain or other wet conditions will not cause electrical safety to be compromised.

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.

The North American Class 1, Zone 0/1 (Class 1, Division 2) product (ASM0627-09-N-Cx-O-

Gx-D3x) was also assessed against the following standards for hazardous environments:

UL 61010-1 / CSA C22.2 No.61010-1-12 Standard for Safety Electrical Equipment For

Measurement, Control, and Laboratory Use Part 1: General requirements

UL 60079-0 / CSA C22.2 No. 60079-0 Standard for Safety Explosive Atmospheres –Part 0:

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.

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.
