. . .10 Hazardous Area considerations
Conditions of Acceptability
The SIL2 version of the Pressure Transmitter, which is identified
by 'NL' being included model designation, is not capable of
passing a 500V r.m.s. dielectric strength test in accordance
Clause 10.3 of ANSI/ISA 60079-11 (12.02.01)-2012 – ANSI/UL
60079-11 Sixth Edition and CAN/CSA-C22.2 No. 60079-11:14
between its Intrinsically Safe circuits and its enclosure.
This shall be considered in any equipment intrinsic safety
installation.
When the Pressure Transmitter is used in a Group III Db
Hazardous Area it shall be installed such that it is not subjected
to flowing dust.
For Group III installations the Pressure Transmitter shall be
fitted with a hazardous location approved cable entry device.
For Group III Ex tb installations this device shall provide ingress
protection of at least IP 6X.
For Group III Ex ia installations this device shall provide ingress
protection of at least IP 5X.
