2.2.1 Hazardous location
Explosion hazard. The GS1440 sensor is not approved for use in hazardous locations.
The GS2440EX sensor is compliant with ATEX (EU), UKEX (UK), IECEx and North American
(US/Canada) hazardous location requirements. Refer to
user to obey all of the conditions of use to keep safety compliance.
• The GS2440EX sensor is an isolated metal part with a maximum capacitance of 97.2 pF on the
enclosure screws. Make sure to use grounding or installation conditions that prevent electrostatic
charging of the GS2440EX sensor. Refer to the instruction manual from the manufacturer for
instructions on how to prevent electrostatic charging.
• The GS2440EX sensor must not be disassembled.
• If the GS2440EX sensor is installed in a hazardous location, it is the responsibility of the end user
to select the correct barriers to use with the sensor.
• Obey all ATEX, UKEX, IECEx, North American Classification Certificate specifications and the
national and local regulations.
• Obey the safety warnings of the other intrinsically safe (Ex) equipment installed near the sensor.
2.2.2 EMI (electro-magnetic interference)
The GS1140 and GS2440EX sensors are compliant with the certifications that follow:
• EU EMC Directive 2014/30/EU
• UKCA Electromagnetic Compatibility Regulations 2016
• FCC Part 15B
• ICES-003
