SERIES 3000 MKIII TECHNICAL MANUAL
MAN0917_Issue 6_08/2015
21. Certification
The Series 3000 MkIII main unit is available in 6 versions: ATEX/IECEx approved version (Aluminium
version part number S3KAL3, Stainless Steel version part number S3KAS3) and UL/CSA approved
version (Aluminium version part number S3KUL3, Stainless Steel version part number S3KUS3) and
Inmetro approved version (Aluminium version part number S3KNL3, Stainless Steel version part number
S3KNS3). The remote sensor accessory has both ATEX and UL/CSA approval on the same part (part
number S3KRMK). The following sections detail the approvals and certification nameplates.
ATEX / IECEx Special Conditions of Use
S3KX***** Series EC Cartridges
When installed in the Series 3000 MkIII Transmitter, the Transmitter's Tamb rating of -20°C to +55°C
must be observed. When the Cartridge is installed remotely using the S3KRMK, a Tamb of -40°C to +55°C
is permissible however "W03 Sensor Operating Limits Exceeded" will be issued when temperatures are
outside limits published in Sec 17. General Specifications.
S3KRMK Remote Mount Sensor Kit
The enclosure of the S3KRMK contains aluminium. Care must be taken to avoid ignition hazards due to
impact or friction when installed in Zone 0 locations.
S3K**3 Series 3000 MkIII Transmitter
The enclosure of the Series 3000 MkIII transmitter contains aluminium. Care must be taken to avoid
ignition hazards due to impact or friction when installed in Zone 0 locations.
Intrinsic Safe Information for Capacitance and Inductance
For installations in which both the Ci and Li of the intrinsically safe apparatus exceeds 1% of the Co and
Lo parameters of the associated apparatus (excluding the cable), then 50% of Co and Lo parameters are
applicable and shall not be exceeded. The reduced capacitance of the external circuit (including cable)
shall not be greater than 600 nF for Group IIC. Be aware that the sensors and S3K-RMK Remote Sensor
Accessory listed in this manual meet these requirements.
