c. ATEX Intrinsically Safe Type/ATEX
Flameproof Type
EJX/EJA-E Series pressure transmitters with
optional code /KU24 can be selected the type
of protection ATEX Flameproof or Intrinsically
Safe. Ex ia for use in hazardous area.
Note 1. For the installation of this transmitter,
once a particular type of protection is
selected, any other type of protection
cannot be used. The installation must be in
accordance with the description about the
type of protection in this user’s manual.
Note 2. For combined approval types, once a
device of multiple approval type is installed,
it should not be re-installed using any
other approval types. Apply a permanent
mark in the check box of the selected
approval type on the certification label on
the transmitter to distinguish it from unused
approval types.
