NOTES:
1. The temperature class (T6) is limited to T4 when the MPD sensor is attached locally to the transmitter.
2. XNX EC cartridges and Remote Mount Kit have been evaluated by Underwriters Laboratories (UL) to
Canadian National Standards.
3. CSA Listing is only to Class I, Division 1 does not include Class II, Div.1 approval
4. Peer to peer and multi-drop network (daisy chained) HART, Modbus®, and FoundationTM Fieldbus
congurations have not been evaluated by CSA to the requirements of CSA 22:2 No. 152 for
Combustible Gas Detection and may be used only for diagnostics and data collection.
