Chapter 1. Installation
Note:
For compliance with the European Union’s Low Voltage Directive (73/23/EEC),
a transparent plastic shroud protects the electrical connections. The shroud
must remain in place, except while wiring the unit. Reinstall the shroud after
the wiring has been completed.
Once the Model GC868 is completely wired, proceed to Chapter 2,
Initial Setup
, to
configure the unit for operation.
1.8.1
Wiring the Line
Power
The Model GC868 may be ordered for operation with power inputs of 100-120 VAC,
220-240 VAC, or 12-28 VDC. The label on the shroud inside the electronics enclosure,
just above the
TB1
line power terminal block, lists the required line voltage and the
fuse rating for the unit (the fuse rating is also listed in Chapter 4,
Specifications
). 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 Model
GC868.
Refer to Figure 1-35 on page 1-25 or Figure 1-42 on page 1-43 to locate terminal block
TB1
and connect the line power as follows:
1.
Remove the plastic shroud that covers the terminal blocks. Be sure to reinstall
the shroud after all of the wiring has been completed.
2.
Strip ¼” of insulation from the end of the power and neutral AC leads (or the
positive and negative DC line power leads), and ½” from the end of the ground
lead.
3.
Connect the ground lead to the internal ground connection located on the side
panel of the enclosure (see Figure 1-35 below).
IMPORTANT:
The incoming ground lead must be connected to the internal ground
connection.
4.
Connect the neutral or line lead (or the negative – DC power lead) to TB1-2 and
the line power lead (or the po DC power lead) to TB1-3 as shown in
Figure 1-35 below.
IMPORTANT:
Do not remove the existing PC board ground wire or the cover ground
wire.
ATTENTION EUROPEAN CUSTOMERS! To meet CE Mark requirements,
all cables must be installed as described in Appendix A, CE Mark
Compliance.
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 and
within the electronics console.
