c CSA Intrinsically Safe Type/CSA
Explosionproof Type
Model EJX Series pressure transmitters with
optional code /CU1 or /V1U can be selected the
type of protection (CSA Intrinsically Safe or CSA
Explosionproof) for use in hazardous locations.
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 instruction manual.
Note 2. In order to avoid confusion, unnecessary
marking is crossed out on the label other
than the selected type of protection when
the transmitter is installed.
