7.2 Connection of modules
CAUTION
Note that the when the Ethernet cable is run in
the same raceway or conduit area it must have
insulation rated to the correct voltages and
listings required. For applications up to 240 VAC
the in insulation must be rated to 300 VAC. For
480 VAC applications use 600 VAC insulation.
The appropriate cables can be provided by
Janitza.
There are different application specifi c DIN Rail CT
Interface Boards that connect to Smart Ports on the
UMG 804 using network cable.
Cables are eight conductor network / Ethernet
cables with RJ45 connector terminations; cables
must have insulation voltages rated for the
environment.
Cable runs between the UMG 804 and Interface
Card can be up to 100 ft (33 m). For distances
longer consult factory for details.
Note:
CAT6A type cables are recommended for
maximum noise immunity.
Cables can also be fi eld constructed from network
cable and terminated with RJ45 connectors. Always
make sure that pin to cable connections on both
sides of the cable match when making custom
cables. Be sure that the mounting area allows for
adequate wire bending radiuses per local and
national electrical codes.

WARNING
Disregard of the connection conditions of the
transformers to Janitza measurement devic-
es or their components can lead to injuries or
even death or to material damage!
· Do not use Janitza measurement devices or
components for critical switching, control or
protection applications (protective relays)! It
is not permitted to use measured values or
measurement device outputs for critical appli-
cations!
· For Janitza measurement devices and their
components use
only “Transformers for mea-
surement purposes”
which are suitable for the
energy monitoring of your system. Do
not use
“Transformers for protection purposes”
!
· Observe the information, regulations and limit
values in the usage information on
“Transform-
ers for measuring purposes”
, specifi cally
during testing and commissioning of the Janitza
measurement device, the Janitza component
and your system.
The UMG 804 is installed by mounting on standard
35 mm DIN rail. The enclosure can be mounted
in any orientation. Secure the DIN rail using a
mechanical fastener such as sheet metal screw or
bolt to a secure surface.
