Rosemount 3051S
Special conditions for safe use (x)
1. The 3051S HART 4-20 mA, 3051S F
OUNDATION fieldbus, 3051S Profibus and 3051S
FISCO are not capable of withstanding the 500V test as defined in clause 6.3.12 of IEC
60079-11. This must be taken into account during installation.
2. The terminal pins of the Types 3051S-T and 3051S-C must be protected to IP20
minimum.

Special conditions for safe use (x)
The apparatus is not capable of withstanding the 500 V insulation test required by Clause 8
of IEC 60079-15.
Combinations of Certifications
Stainless steel certification tag is provided when optional approval is specified. Once a device
labeled with multiple approval types is installed, it should not be reinstalled using any other
approval types. Permanently mark the approval label to distinguish it from unused approval types.
