Rosemount 3051S Series
B-8
IECEx Dust
Certificate No. IECExBAS09.0014X
Ex tD A20 T105°C (-20 °C ≤ T
amb
≤ 85 °C)
Vmax = 42.4 V
A = 22 mA
IP66
Special conditions for safe use (x)
1. Cable entries must be used which maintain the ingress protection of the enclosure to at
least IP66.
2. Unused cable entries must be filled with suitable blanking plugs which maintain the
ingress protection of the enclosure to at least IP66.
3. Cable entries and blanking plugs must be suitable for the ambient range of the
apparatus and capable of withstanding a 7J impact test.
4. The 3051S must be securely screwed in place to maintain the ingress protection of the
enclosure. (The 3051S SuperModule must be properly assembled to the 3051S housing
to maintain ingress protection.)

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.
