Safety Information - Crowcon IRmax M20 Instrucciones De Instalación, Operación Y Mantenimiento

Concept and safety

Safety information

• IRmax gas detectors must be installed, operated and maintained in strict accordance
with these instructions, warnings, label information, and within the limitations stated.
• The rear nut on IRmax must be kept tightly closed during operation. Do not attempt
to remove the rear nut until power to the detector is isolated - otherwise ignition
of a flammable atmosphere can occur. Before removing the nut for maintenance,
calibration or servicing, check that the surrounding atmosphere is free of flammable
gases or vapours. Do not open until several minutes after the power has been removed.
• Maintenance and calibration operations must only be performed by qualified service personnel.
• Only genuine Crowcon replacement parts must be used; substitute components may
invalidate the certification and warranty of the IRmax.
• IRmax must be protected from extreme vibration, and direct sunlight in hot
environments as this may cause the temperature of the IRmax to rise above its specified
limits and cause premature failure.
• IRmax will not detect hydrogen, ammonia or carbon dioxide.
• The equipment must be earthed using the cable gland and steel armoured cable.
• Certification for Zone 21/22 dust environments: IRmax basic (without IR Display or
IS Barrier module) may be used in environments that may contain hazardous dusts
(Zones 21 or 22).
• IRmax with an IS Barrier module may be used in Zones 21 or 22 provided the ambient
temperature remains below 40°C and a remote IR Display or Hand-Held IR Displays are
installed/used outside the hazardous area only.
• IRmax with a Fixed IR Display cannot be installed in a Zone 21 or 22 area.
