2.12 Wiring the Sampler
1. Disconnect all power to the 980 Flow Meter. See 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 insulation from the sampler leads ¼ inch.
Note: Route wires through
NEMA-approved conduit hubs
(Cat. No. 16483) to ensure
that water and dust do not enter the
enclosure.
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 wires
through this opening.
5. Connect wires to the proper screw terminal block (TB10).
Refer to Ta bl e 8 and Figure 18 for wire connections.
Cable Required for Sampler Connections
• Multi-Purpose Half Cable Assembly, 10 ft (3.0 m), 6-pin connector on one
end, tinned wire leads on the other end (Cat. No. 9708700).
