Wiring The Line Power - GE AquaTrans AT868 Abridged Manual

Wiring the Line Power

Installation
The AT868 may be purchased for operation with power inputs of
85-265 VAC or 12-28 VDC. The label on the side of the electronics
enclosure lists the required line voltage and power rating. The fuse
rating is listed on label located under the fuse.
IMPORTANT: Be sure to connect the meter only to the specified line
voltage.
Note: For compliance with the European Union's Low Voltage
Directive (73/23/EEC), 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.
Refer to Figure 1-5 on page 1-16 to locate the power input terminal
block and connect the line power as follows:
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. 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. (12 mm) 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 where the line
power wires will enter the enclosure. If possible, avoid using a
conduit hole containing any other cables cables, 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 the power terminal block as shown in Figure 1-5
on page 1-16.
