Det-Tronics OPECL Infrared Hydrocarbon Gas Detector - Manual (Page 34)

95-8556 10.1 C-2
ATEX Special Conditions for Safe Use for the [ib] HART communication port only:
• The intrinsically safe output on the HART Communicator Port is internally connected to frame.
• Um is restricted to 250 V, prospective short circuit current < 1500 A.
• When connecting to a circuit using up to 1% of Co or Lo, then the C or L is limited to the Co and Lo listed above. If
either the C or L is above 1% of Co or Lo, then C or L are each limited to 50% of the Co or Lo listed above.
• The Infrared Hydrocarbon Gas Detectors shall be powered from a SELV isolating transformer and the fuse for Isc
shall be of the type complying with IEC60127.
WARNING
Always ensure that the detector/junction box hazardous (classified) location ratings are applicable for the
intended use.
Additional Safety Notes:
• For ambient temperatures below –10°C, use field wiring suitable for the expected conditions, and for ambient
temperatures above +60°C, use field wiring suitable for 20°C above the maximum expected conditions.
