1.5.4 Wiring the Line Power

The XMT1000 may be ordered for operation with power inputs of either 100-240 VAC or 12-28 VDC. The label on the
side of the enclosure lists the meter's required line voltage and power rating. Be sure to connect the meter to the
specified line voltage only.
Attention European Customers! For compliance with the European Union's Low Voltage Directive,
this unit requires an external power disconnect device such as a switch or circuit breaker. The
disconnect device must be marked as such, clearly visible, directly accessible, and located within
1.8 m (6 ft) of the unit.
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.
Refer to Figure 6 on page 8 to locate the terminal blocks and connect the line power as follows:
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 gland in the conduit hole. If possible, avoid using the other conduit holes for this
purpose, to minimize any interference in the circuitry from the AC power line.
Attention European Customers! To meet CE Marking requirements, all cables must be installed as
described in "CE Marking Compliance" on page 1.
3. Route the cable through the conduit hole and connect the line power leads to the power terminal, using the pin
number assignments shown in Figure 6 on page 8.
IMPORTANT: The ground wire must be connected to the system chassis.
4. Leaving a bit of slack, secure the power line with the cable clamp.
5. If wiring of the unit has been completed, reinstall the wiring cover on the enclosure and tighten the set screw.
WARNING! Make sure all covers, with their o-ring seals, are installed and the set screws tightened
before applying power in a hazardous environment.
CAUTION! The transducers must be properly wired before applying power to the meter.
