3.18 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.
Note: Numeric code in junction box label matches wire labels.
