2.6.1 Input Power Connections
To access the wiring terminal blocks, locate and loosen the small set screw which locks the small enclosure cover in
place. Unscrew the cover to expose the terminal block.
2.6.1.1 AC Power Wiring
CAUTION!
The AC wire insulation temperature rating must meet or exceed 90°C (194°F), maximum
operating voltage 600VRMS.
The AC power wire size must be 10 to 20 AWG with 1/4 inch (7 mm) of insulation stripped from each conductor. The
wire insulation temperature must meet or exceed 90°C (194°F). Connect 100 to 240 VAC (5 W maximum) to the
Hot
and Neut terminals on the terminal block (see Figure 33 below), and connect the ground wire to the safety ground
lug . Torque all connections to 4.43 to 5.31 in-lbs (0.5 to 0.6 Nm). Use a separate conduit entry for signal lines to
reduce the possibility of AC noise interference.

2.6.1.2 DC Power Wiring
WARNING!
Use a Class 2 isolated power supply that is grounded, provides DC output, and has no
more than 10% output ripple.


A power switch is not provided with this meter, an approved switch meeting the power
requirements listed in Appendix A must be provided by the user. It must be easily
accessible and marked as the disconnect for the flow meter.


Only the connectors supplied with the meter are to be used for connecting wiring.


If the equipment is used in a manner not specified the protection provided by the
equipment may be impaired.
CAUTION!
The DC wire insulation temperature rating must meet or exceed 85°C (185°F),
maximum operating voltage 300 VRMS.
The DC power wire size must be 20 to 12 AWG with 1/4 inch (7 mm) of insulation stripped from each conductor. The
wire insulation temperature must meet or exceed 85°C (185°F). Connect 18 to 36 VDC (300 mA, 9 W maximum) to the
+DC Pwr and –DC Pwr terminals on the terminal block (see Figure 34 below). Torque all connections to 4.43 to 5.31
in-lbs (0.5 to 0.6 Nm).
