4. WIRING
4.5 Wiring Cautions
(1) Lay wiring as far as possible from electrical noise
sources such as large transformers, motors and power
supplies.
(2) It is recommended that crimp-on type solderless lugs be
used for large wire ends.
(3) For general use, it is recommended that conduits and
ducts or racks be used to protect wiring from water or
mechanical damage. A rigid steel conduit or flexible
metal conduit is recommended. See Figure 4.9.

4.6 Grounding
(1) For analog output version, ground the primary circuit in
the power supply and the ground terminal of the
flowmeter terminal box.
(2) For pulse output version, ground the flowmeter. Also
ground the shielded cable between the converter and the
pulse receiver.
(3) Grounding should satisfy Class D requirements (ground
resistance 100
Ω
or less).
(4) Use 600V PVC insulated wire for grounding.
