Chapter 3. Wiring the AT600 electronics
3.2 Wiring the line power
The AT600 may be ordered for operation with power inputs of either 85-264 VAC or 12-28 VDC. The label on the shroud
inside the electronics enclosure lists the required line voltage for your meter.
Examples of AT600 labels indicating the required line voltage are shown in figure 25 below.
Refer to Figure 23 on page 19 to locate the terminal block and connect the line power as follows:
1. Strip 1/4” of insulation from the end of the line and neutral AC leads (or the positive and negative DC leads), and
1/2” of insulation from the end of the ground lead.
2. Connect the ground lead to the internal ground connection (GROUNDING 1) located on the bottom panel of the
electronics enclosure (See Figure 23 on page 19).
IMPORTANT: The incoming ground lead must be connected to the internal ground connection.
3. Connect the neutral AC lead (or the negative - DC lead) to L2/N(-) and the AC line lead (or the positive DC lead) to
L1(+), as shown in Figure 23 on page 19.
IMPORTANT: Do not remove the existing PC board ground wire or the cover ground wire.
Attention European Customers!To meet CE marking requirements, all cables must be installed as
described in "Wiring cable specifications and requirements" on page 144.
WARNING!
Be sure to connect the AT600 only to the specified line voltage.
Attention European Customers! For compliance with the European Union’s low voltage directive, this
unit requires and 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 will damage the unit. It will also result in hazardous voltages at the flowcell
and associated piping and within the electronics console.
