Wiring the Line Power
(cont.)
Refer to Figure 1-4 on page 1-14 to locate the power terminal block
and connect the line power as follows:
!WARNING!
Improper connection of the line power leads or connecting
the meter to the incorrect line voltage may damage the
unit. It may also result in hazardous voltages at the
flowcell and associated piping as well as within the
electronics enclosure.
1. Follow the instructions on page 1-4 to prepare the unit before you
connect power.
2. 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.
3. Install a suitable cable clamp in the conduit hole where the line
power is fed through. If possible, avoid using a conduit hole
containing input/output cables for this purpose, to minimize any
interference in the circuitry from the AC power line.
!ATTENTION EUROPEAN CUSTOMERS!
To meet CE Mark requirements, all cables must be installed
as described in Appendix B, CE Mark Compliance.
4. Strip 1/4-in. of insulation from the end of each of the three line
power leads.
5. Route the cable through the conduit hole and connect the line
power leads to the power terminal block as shown in Figure 1-4 on
page 1-14.
6. Leaving a bit of slack, secure the power line with the cable clamp.
Caution!
The transducers must be properly wired
before applying power to the meter.
7. Do one of the following:
• Proceed to the next section to continue wiring the Model AT868
flow transmitter.
• Reinstall the plastic shroud, replace the front cover on the
enclosure and tighten the screws.
