Installation and maintenanceshould only be performed by
qualified and competent personnel who have b een properly
trained to handle high vo ltage and current devices in accordance
with localand national electrical codes.
Hazardous voltage can causeelectric shock, burn or explosion.
Disconnect and lockout power s ource, open all PT secondaries
and short all CT secondaries before servicing. Failure to observe
proper precaution may result in serious injury ordeath.

Mounting the Meter
The iMeter 7A should be installed in a dry environment with no dust
and kept away from heat, radiation and electrical noise sources.
Installation steps:
▪Remove the mounting brackets from the meter
▪Fit themeter through a 138mm x 138mm cutout
▪Re-installthemounting bracketsandtightenthescrews againstthe
panel to secure the meter
Using the Front Panel Buttons
The Front PanelDisplay allows usersto access different measurements andperform basic configuration. Thereare five menus
in the Home Page, <Metering>, <Power Quality>, <PQ Insight>, <Events> and <Setup>. Each menu includes multiple sub-
menus for measurements, events or setup parameters. The following table provides an overview of the Front Panel buttons.

The four arrow buttons are usedfor navigation betweendifferentmenus in the Home Page.The current cursor location is
indicated by a larger icon where its available sub-menus are listed at the bottom of the screen for reference.
Before a sub-menu is selected,
•Press <> or <> to navigate the sub-menulist.
Aftera sub-menu is selected,
•Press <> or <> to display different pages of parameters.
•Use <> or <> to scroll to differentpages of Individual Harmonic or
Interharmonic measurements from 1st to 63rd in the Harmonics or
Interharmonics sub-menu.
•In the WFR and DWR page, press <> or <> to scroll backward or
forward through the waveform and <> or <> to zoom in/out of the
waveform.
Before a parameter is selected,
•Use <>, <>, <> and<> buttons
to navigate around.
If a parameter is selected,
•For a numeric parameter, press <>
or <> to increment or decrement a
numeric value.
•For an enumerated parameter, press
<> or <> to scroll through the
selection list.
<>
•Press <> to enter the selected Menu/Sub-menu
•In TOU, press<> to toggle between Energy and Max. Demand.
•In Max., Min., and 2-150kHz C.E., press <>toscroll through different
pages of measurements.
•In Harmonics / Interharmonics, press <> to view the Individual
Harmonics or Interharmonics details.
•In PQ Insight, press <> to Pause/Refresh the WF Capture, toggle the
signal selection for WF display, manually trigger WFR/DWR or view the
latest event details.
Before a parameter is selected,
•pressing <>selects a parameter for
modification.
Aftera parameter is selected,
•pressing <>saves the present value
of the selected parameter into
memory.
