IMPORTANT NOTICE
Use this Guide to begin performing basic
metering functions quickly, without reviewing
complete instructions provided in the User’s
Manual. To more fully understand the wide
array of features offered by your IQ Analyzer,
it is strongly recommended that operators
read the User’s Manual.
Following initial power-up of the IQ Analyzer,
the displayed “Meter Menu” values may not
be what is anticipated for your specific system.
The unit must first be programmed with
“General Setup” information relating to your
electrical system.

Introduction
Introduction
The IQ Analyzer is a compact, panel mount-
ed, micro-processor based device for users
who want to monitor all aspects of their
electrical distribution system. It has been
engineered to provide comprehensive
metering, power quality analysis, remote
input monitoring, control relaying, analog
inputs/outputs and communications
capabilities. It will replace dozens of existing
individual meters, recorders, and relays.
The IQ Analyzer displays a comprehensive
list of metered parameters, historical values,
harmonic profiles, peak demands and alarm
data. Custom screens may be easily pro-
grammed to conveniently view parameter
groupings, or to concurrently observe rela-
tionships as system conditions change.
Information display options and device pro-
gramming are accessible through a commu-
nications port via IMPACC (Integrated
Monitoring Protection and Control
Communications), or directly at the Operator
Panel using Meter Menu and Function Keys.
The IQ Analyzer directly monitors 3-phase
lines to 600 Vac without the need for
external potential transformers. Above 600
Vac, external transformers are required.
The device complies with rigid ANSI C12.16
Class 10 revenue meter accuracy standards,
and provides true rms readings through the
50th harmonic. Accuracy is maintained in
applications with high distortion levels,
including systems exhibiting 3.0 Crest
Factor.

4 K-Factor: A derating factor that is essentially the sum of the
squares of individual harmonic currents times the squares of
their harmonic number (i.e., multiples of fundamental). One
for each current is displayed with largest recorded in Event
metered data.
5CBEMA Factor: A transformer harmonic derating factor defined
as a pure sine wave’s crest factor (1.414) divided by the mea-
sured crest factor.
6Crest Factor: The ratio of peak current to rms current.

This password protected mode is used to configure
the Unit. Use Program Mode to specify General
Setup Settings and for advanced features.
Reset Mode:
(USER’S MANUAL SECTION 5-10)
Using this password protected mode, the operator
can reset or clear certain items such as Min/Max val-
ues, Alarm Triggers, Relays and Peak Demand
Values.
Help Mode:(USER’S MANUAL SECTION 5-3)
The IQ Analyzer displays various Help screens and
useful information relating to device operation, pro-
gramming and troubleshooting.
Modes of Operation
Communications
(USER’S MANUAL SECTIONS 5-8)
TheIQ Analyzer is an IMPACC (Integrated
Monitoring Protection and Control
Communications) compatible device. It can be
remotely monitored, controlled and programmed
when equipped with the communications option.
The small, addressable communications module
(IPONI), is mounted to the back of the IQ Analyzer.

The IQ Analyzer is typically mounted on an
enclosure door. This installation makes it
necessary to prepare a cutout into which the
device will be placed. Top, bottom and two
center side holes are used to mount the unit.
A flange mounting option and separate
NEMA 12/3R enclosure are available.
Contact your local distributor or sales office.

When the IQ Analyzer is initially powered up, it is
in Display Mode. The “Normal LED” will blink
green and the “Current LED” will glow red. The
display will show phases A, B and C currents in
amperes for the system being monitored.
Initial Meter Menu Current Screen
The Up and Down pushbuttons (PBs) provide fast
access to other Meter Menu parameters such as
those outlined in the table. The Function pushbut-
tons (F1-F4) access TRND, EVNT, HARM and
DEMD from the Display Mode. These are Analysis
Modes for Trend, Event, Harmonic and Demand
information.
Note on Sign Convention
(USER’S MANUAL SECTIONS 5-22)
As a factory default, lagging vars and power factor
are represented as negative values at the load.
This is a negative sign convention consistent with
P=VI. The alternative is a power engineering con-
vention which uses P=VI such that consumption of
power is positive. This sign convention can be
changed in the Program Mode under Power/
Energy Options in General Setup. Changing this
setting will have no effect on the unsigned “LEAD-
ING KVAR-HR” and “LAGGING KVAR-HR” ener-
gy readings. However, the “NET KVAR-HR” ener-
gy will begin counting in the opposite direction.
Manual Capture
(USER’S MANUAL SECTIONS 5-7.2.5.12)
Capture and store system values for analysis and
to aid in verifying proper operation of the
IQ Analyzer by using Manual Capture. Enter the
Harmonic Analysis Mode from Display Mode
using the F3 Function PB. In the Harmonic
Analysis Mode, the unit captures new system mea-
surements when the F4 pushbutton (NEW) is
pressed twice. (F3, F4, F4)
NOTE: For proper operation, an Event Trigger must be
set to Manual Capture. This can be done in the Event
Triggers section of the Program Mode.

WARNING !
Wiring procedures must be performed only by
qualified personnel who are familiar with the
IQ Analyzer and its associated electrical equipment.
Ensure that incoming ac power (or foreign power)
sources are turned off and locked out prior to
performing any electrical work. Failure to do so may
result in serious injury or death, or equipment
damage. The only exception is when connecting/
disconnecting ribbon cables at J2 or J3.
11
Wiring installation for the IQ Analyzer must
follow a suitable Wiring Plan Drawing and
conform to applicable Federal, State and
Local codes.
Wires to the terminal blocks must not be larg-
er than AWG No. 14. Larger wire sizes may
be used on the CT connections when using
appropriate ring terminals.
The following two figures show typical
wiring diagrams. Additional wiring diagrams
are shown in the User’s Manual.
