3.25 Remote electronics wiring
The remote electronics enclosure should be mounted in a convenient, easy to reach
location. For hazardous location installations, make sure to observe agency requirements
for installation. Allow some slack in the interface cable between the junction box and the
remote electronics enclosure.
To prevent damage to the wiring
connections, do not put stress on the
terminations at any time.
The meter is shipped with temporary
strain relief glands at each end of
the cable. Disconnect the cable from
the meter's terminal block inside the
junction box-not at the remote electronics
enclosure. Remove both glands and
install appropriate conduit entry glands
and conduit. The cable entry device shall
be of a certified flameproof type, suitable
for the conditions of use and correctly
installed. The degree of protection of at
least IP66 to EN 60529 is only achieved
if certified cable entries are used that are
suitable for the application and correctly
installed. Unused apertures shall be
closed with suitable blanking elements.
When installation is complete, reconnect
each labeled wire to the corresponding
terminal position on the junction box
terminal block. Make sure to connect each
wire pair's shield.
Note: incorrect connection will cause the
meter to malfunction.

matches wire labels.
3.26 Optional input electronics wiring
The meter has two optional input wiring terminals. These can be used to input a Remote
or Second RTD input in the case of an Energy Monitoring meter, for the input of a Remote
Pressure Transducer, to pass a Contact Closure or for a Remote Density measurement to
name a few. In any case, the wiring diagram will be included with the meter if any of the options
are specified. Otherwise, the optional terminal blocks will be left blank and non functional.
