2. Applicable standards
IEC 60079-0:2011
IEC 60079-11:2011
3. Instruction for safe use
3.1 To maintain the degree of protection of at least IP66 in accordance with IEC
60529, suitable cable entries must be used and correctly installed. Unused
openings must be closed with a suitable stopping plug.
3.2 Thread type of entry
When Model No. is given with JTx9xxx-x … x-yx … x-x …
If y=X, 2, or 3, the thread type of entries is G1/2, or
If y=A, the thread type of entries is 1/2NPT.
4. Special conditions for safe use of intrinsic safety Ex ia (X certificate)
If the enclosure of the transmitter is aluminium, and if it is mounted in an area
where the use of EPL Ga equipment is required, it must be installed such that,
even in the event of rare incidents, ignition sources due to impact and friction
sparks are excluded.
For the use in the area where an EPL Da apparatus is required, electrostatic
discharge shall be avoided.
