Figure 14 Locating TB4 and TB9 for Analog Input Connections
2.9 Wiring the Mechanical Totalizer
Note: Use NEMA-approved conduit
hubs (Cat. No. 16483) to ensure
that water and dust do not enter the
enclosure.
1. Disconnect all power to the 980 Flow Meter. Refer to Wiring Safety
Information on page 31.
2. Use a large flat-blade screwdriver to loosen the two screws securing the
980 Flow Meter cover. Open the cover.
3. Strip the insulation from the mechanical totalizer leads ¼ inch.
4. Attach a NEMA-approved conduit or compression fitting to one of the
½ in. openings on the bottom of the instrument, and route the cable wires
through this opening.
5. Connect wires to the proper terminal block connection (TB7), shown in
Table 5 and Figure 15.
