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.
