SPU Overview

2 SPU Overview
The SPU box contains two separated compartments; a main and a rear
compartment (see Figure 2-1 and Figure 2-2). The main compartment can
be opened from the side of the SPU and contains the most important circuit
boards. All connections herein are factory set and should not be adjusted on
site. It is strongly advised to only open this compartment after consultation
with Elster.
For all external connections to the meter the connection holes in the bottom
of the rear compartment should be used (see Figure 2-2). Five connection
holes are provided; the thread type can be either M20 or ½” NPT. Unused

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.
