holes shall be equipped with certified stopping plugs; non-certified plugs
(e.g. used for transport or storage) shall also be replaced by certified plugs.
The client is responsible to provide suitable glands and stopping plugs, with
regards to e.g. thread type, hazardous area certification, ingress protection.
The rear compartment contains the field terminal board (see Figure 2-3). All
connections for external wiring are placed on this PCB, therefore when
connecting to a flow computer only the connection on this PCB should be
used. For long distance network connections an optional DSL modem can
be placed behind the field terminal board.

3 Installation Instructions
Suitable armored shielded cables must be used for wiring the meter
(communication cables should also be twisted), whereby the cables are
protected from mechanical damages as well as electrical interference. In
addition, ensure the length, diameter, core, and resistance of the cables are
an optimal match for the particular application.
For making reliable and durable connections to your UFM it is highly
recommended to use insulated wire end terminals. To avoid cables hanging
in the glands; all cables must be clamped and cleated properly and close to
the UFM connections. The SPU can rotate almost 360°, keep this in mind
when wiring your meter. Ensure the wires can rotate as well, if needed.
