** 480 VAC only applies to the H8163 and H8167
Connect white wire to (-).
Connect red/black/yellow wire to (+).
5. Use color coding to attach current transformer (CT) leads to the input terminals
(e.g. red labeled lead to red terminal). Polarity is indicated in the wiring diagrams,
but the meter is not polarity sensitive. See the Wiring section.
6. Use color coding to connect voltage leads to phase conductors (e.g. red
transformer lead to red terminal). The meter is powered from the monitored
source, so connect the voltage leads to a circuit that is normally left on. See the
Wiring section.
7.
H8163 and H8167:
Connect the output terminals to the control/data acquisition
system. The Pulse Output is normally open. For the H8163, the Phase Loss Output
is normally open, and for the H8167, it is normally closed. Both are rated for 24
VAC/VDC@100 mA maximum. Ensure that the installation method and insulation
ratings conform to local and national electrical codes.
8. Set the backlight enabling jumper as desired. Remove the jumper to disable the
backlight.
9. Set the Display Data jumper for either Plain or Full settings. Plain mode cycles
the display through five data elements (kW, max. kW since last reset, average PF,
line-to-line voltage, and amps) for four seconds each. Full mode cycles through all
of the data available in the meter. See the Information Reporting section for more
details.
