Chapter 1. Installation
1.7.1 Wiring the Line Power (cont.)
1. Prepare the line power leads by trimming the line and neutral AC power leads (or the positive and negative DC
power leads) to a length 0.5 in. (1 cm) shorter than the ground lead. This ensures that the ground lead is the last
to detach if the power cable is forcibly disconnected from the meter.
2. Install a suitable cable clamp in the conduit hole indicated in Figure 10 on page 23. If possible, avoid using the
other conduit holes for this purpose, to minimize any interference in the circuitry from the AC power line.
3. Strip 1/4-in. of insulation from the end of each of the three line power leads.
4. Route the cable through the conduit hole and connect the line power leads to terminal block
TB5
, using the pin
number assignments shown in Figure 10 on page 23.
5. Leaving a bit of slack, secure the power line with the cable clamp.
Proceed to the next section to continue the initial wiring of the Model XMT868i flow transmitter.
