CONDITIONS OF ACCEPTABILITY- Due to the risk of discharge the non-metallic parts of the equipment and of all non-metallic
accessories have to be protected from electrostatic charging during installation and operation(e.g. only wipe with damp cloth and do not expose to high voltage fields).
- The equipment is for use under atmospheric conditions only, the permissible pressure range isto 1.1 bar (80 to 110 kPa) and the permissible normal oxygen content is typically 21 % v/v.
- The end user shall ensure appropriate earthing of the metallic field housing (optional) and all
metallic accessories if used (wall or pipe mounting accessories for the field housing and the DIN railclip for the head transmitter) upon installation.
- For the use as an intrinsically safe equipment, and for Zone 0 (EPL Ga), Zone 1 (EPL Gb) and Class I,
Division 1 applications, the head transmitter TMT71/TMT72/L20221/L20222 shall be installed
completely inside an additional enclosure, providing a degree of protection of not less than IP20
according to CSA/UL 60079-0 and CSA/UL 60079-11. The ambient temperature within the end use
enclosure shall not exceed the limits of the permissible ambient temperature range. Clearances,
creepage distances and separations as defined in CSA/UL 60079-11 must be considered for theinstallation.
- If the head transmitter TMT71/TMT72/L20221/L20222 was used in a Zone 1 (EPL Gb), Zone 2(EPL Gc) or Class I, Division 2 application it is not allowed to use it in Zone 0 (EPL Ga) or Class I,Division 1 applications in the future.
- When connecting the head transmitter TMT71/TMT72/L20221/L20222 with a certified circuit ofcategory “ib” into an IIC or IIB hazardous area the ignition class changes to: Ex ib IIC or Ex ib IIB.
- The use of the display type TID10 with the head transmitter TMT71/TMT72/L20221/L20222 byconnecting display to the CDI interface of the head transmitter is only permitted for Zone 1 (EPL Gb),Zone 2 (EPL Gc) and Class I, Division 2 applications.
- The CDI interface is only allowed to be used for connecting the display type TID10. Irrespective of
inside or outside the hazardous area, no other circuits/equipment is allowed to be connected to theCDI Interface.
- The use of the additional field housing (optional) with the head transmitter
TMT71/TMT72/L20221/L20222 is only permitted for Zone 1 (EPL Gb), Zone 2 (EPL Gc) and Class I,Division 2 applications.
- Final acceptance of this equipment when installed is subject to the jurisdiction of the local inspection
authority.
