2.4.3 Wiring the Line Power
The
Sentinel LNG
may be ordered for operation with a power input of 100-240 VAC or 12-32 VDC (see the
Electronics
Ordering Information
in Table 5 on page 10). The label on the side of the electronics enclosure lists the required line
voltage and power rating. The fuse size is listed in
Specifications
in Chapter 1. Be sure to connect the
Sentinel LNG
to
the specified line voltage only.
Note:
For compliance with N. American and European Low Voltage Directive (2006/95/EC), 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
.
Note:
Use one conduit inlet for power. Use the two other conduit inlets for input/output as needed. All unused
conduit inlet ports should be sealed with suitable blanking elements.
See Figure 13 on page 23 to locate terminal block TB1 and to connect the line power as outlined below:
WARNING!
Improper connection of the line power leads or connecting a Sentinel to the incorrect line voltage
may damage the unit. It may also result in hazardous voltages at the meter body and associated
piping as well as within the electronics enclosure.
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.
Figure 12: Conduit Inlet Ports
2.
Route the cable through one of three conduit inlet ports (see Figure 12 above) and connect the line power leads
to the terminal block TB1, using the pin number assignments shown in Figure 27 on page 34 and Figure 13 or
WARNING!
To meet CE Mark requirements, all cables must be installed as described in Appendix B,
CE Mark Compliance
.
