When installing this apparatus in a potentially hazardous area, the following requirements must be met:
• The installation shall comply with IEC 60079-14.
• Apparatus Markings:
Ex d IIC T6 Gb
• Supply connection wiring shall be rated at least 10°C above rated ambient temperature of 60°C. Cable entries
are 3/4” NPT.
• Certificate Number: IECExFMG12.0011X
Complies with IEC 60079-0: 2011 and IEC 60079-1: 2007
Manufacturer: GE Infrastructure Sensing, Billerica, MA.
• The certification covers the following GE product types ― XMT868, XMT868i, XGF868, XGF868i, XGN868, XGN868i,
XGS868, XGS868i, XGM868, XGM868i, IGM878 &: IGM878i.
• This apparatus is equipment category 2 and may be employed in Zones 1 and 2. It may not be employed in a Zone 0
area. This apparatus is certified for gas hazards only.
• Enclosure Material: Si=95, Mg=0.35%, Mn=0.5%, Al = remainder.
• This apparatus must be securely mounted using the mounting fixtures provided on the enclosure.
• All covers are fitted with a locking device. This device must be tightened after the cover is replaced so as to preserve
the protection offered by the enclosure.
• Modifications to the flameproof enclosure are not permitted.
• Cable glands of an approved flameproof design are required. These must be installed according to the manufacturer's
instructions. Where the cable glands are provided by GE Sensing, the manufacturer’s instructions, as supplied to GE
Sensing, will be included in the documentation.
• Connecting cable shall be mounted securely and protected from mechanical damage, pulling and twisting.
• Unused entries must be sealed using a certified threaded plug.
• The apparatus should be de-energized before opening.
• If live working is necessary, the apparatus may only be opened when the surrounding atmosphere is known to be
safe. Measures must be taken to ensure that it remains safe while the unit is open, such as a system of hot work
permits.
• The apparatus uses standard printed circuit assemblies. Always quote the apparatus serial number when ordering
spares.
• This flameproof apparatus is only designed to be installed in a potentially hazardous area. This apparatus has not
been designed for use in a safe area, where it would be subject to CD 2006/95/EC (LVD). For a safe area installation, an
external mains disconnect must be provided close to this apparatus. If in doubt, consult GE.
