1.7 Making Electrical Connections
This section contains instructions for making all the necessary electrical connections to the Model GF868 flowmeter.
See Figure 9 on page 18 for a complete wiring diagram.
Except for the power connector, all terminal blocks are stored in their terminal blocks during shipment and are
removable for more convenient wiring. Feed all cables through the conduit holes on the bottom of the enclosure, attach
the wires to the appropriate connectors, and plug the connectors back into their terminal blocks.
Note: If your unit complies with the European Union’s Low Voltage Directive, it has a transparent plastic cover over
the electrical connections. This cover must remain in place except while you are wiring your unit. Reinstall the
shroud after the wiring has been completed.
Once the GF868 is completely wired, proceed to Chapter 2, Initial Setup, to configure the unit for operation.
1.7.1 Wiring the Line Power
The Model GF868 may be ordered 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 line voltage setting and
fuse rating for your unit. (The fuse rating also appears in Chapter 4, Specifications.) Be sure to connect the meter only
to the correct line voltage. The allowable line voltages and fuse ratings are shown in Table 1 on page 9.
Note: For compliance with the European Union’s Low Voltage Directive, 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 6 ft (1.8 m) of the GF868.
