3.2 Wiring the Line Power (cont.)
Refer to Figure 23 on page 23 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 23 ).
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 23 .
IMPORTANT:
Do not remove the existing PC board ground wire or the cover ground wire.
3.3 Wiring the Transducers
Wiring a typical AT600 system requires interconnection of the following components:
•
Upstream and downstream transducers Installed in the clamping fixtures)
•
The electronics console
To wire the transducers, complete the following steps:
1. Locate the two transducer cables and connect them to the transducers.
2. Connect the cable connector with yellow
DN
jacket on the cable to the
DN
terminal, and connect cable
connector with white
UP
jacket on the cable to the
UP
terminal, as shown in Figure 23 on page 23 .
3. Secure the cable gland.
IMPORTANT:
Be sure to insert all cable connectors straight into the PCB receptacles to avoid damaging the
connector and/or the receptacle.
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.
ATTENTION EUROPEAN CUSTOMERS!
To meet CE Mark requirements, all cables must be installed
as described in “Wiring Cable Specifications and Requirements” on page 177 .
WARNING! Before connecting the transducers, take them to a safe area and discharge any static
build-up by shorting the center conductor of the transducer cables to the metal shield on the cable
connector.
