LIMITED WARRANTY
The manufacturer offers the customer an 24-month functional warranty on the
instrument for faulty workmanship or parts from date of dispatch from the
distributor. In all cases, this warranty is valid for 36 months from the date of
production. This warranty is on a return to factory basis.
The manufacturer does not accept liability for any damage caused by instrument
malfunction. The manufacturer accepts no responsibility for the suitability of the
instrument to the application for which it was purchased.
Failure to install, set up or operate the instrument according to the instructions
herein will void the warranty.
Your instrument may be opened only by a duly authorized representative of the
manufacturer. The unit should only be opened in a fully anti-static environment.
Failure to do so may damage the electronic components and will void the
warranty.
NOTE
The greatest care has been taken to manufacture and calibrate your instrument.
However, these instructions do not cover all possible contingencies that may
arise during installation, operation or maintenance, and all details and variations
of this equipment are not covered by these instructions.
For additional information regarding installation, operation or maintenance of this
instrument, contact the manufacturer or your local representative or distributor.
IMPORTANT
Please read the instructions this manual before performing installation,
and take note of the following precautions:
Ensure that all incoming AC power and other power sources are
turned OFF before performing any work on the instrument. Failure to
do so may result in serious or even fatal injury and/or equipment
damage.
Before connecting the instrument to the power source, check the labels on
the side of the instrument to ensure that your instrument is equipped with
the appropriate power supply voltage, input voltages, currents and
communication protocol for your application.
Under no circumstances should the instrument be connected to a
power source if it is damaged.
To prevent potential fire or shock hazard, do not expose the
instrument to rain or moisture.

ii
The secondary of an external current transformer must never be allowed
to be open circuit when the primary is energized. An open circuit can cause
high voltages, possibly resulting in equipment damage, fire and even
serious or fatal injury. Ensure that the current transformer wiring is made
through shorting switches and is secured using an external strain relief to
reduce mechanical strain on the screw terminals, if necessary.
Setup procedures must be performed only by qualified personnel
familiar with the instrument and its associated electrical equipment.
DO NOT open the instrument under any circumstances.
Modbus is a trademark of Modicon, Inc.
Read this manual thoroughly before connecting the meter to the current
carrying circuits. During operation of the meter, hazardous voltages are
present on input terminals. Failure to observe precautions can result in
serious or even fatal injury or damage to equipment.

1.1 About This Manual
This manual is intended for the user of the C191HM Powermeter. This
Powermeter is a microprocessor-based instrument used for the measurement,
monitoring, and management of electrical parameters.
This chapter gives an overview of this manual and an introduction to the
C191HM.
Chapter 2, Installation, provides instructions for mechanical and electrical
installation.
Chapter 3, Using the Menus, presents the structure of menus for setup and
status viewing.
Chapter 4, Setup Menus, provides instructions for performing parameter setup
via the front panel.
Chapter 5, Data Display, guides you through the display pages.
Chapter 6, Viewing Status Information, tells you how to access additional status
information on the instrument. This information may be useful during installation.
Chapter 7 contains Technical Specifications for the C191HM.
1.2 About The C191HM
The C191HM is a compact panel mounted three-phase AC Powermeter and
Harmonic Manager, specially designed to meet the requirements of users
ranging from electrical panel builders to substation operators. The C191HM
provides basic voltage, current, frequency, power, power factor and energy
measurements, plus total harmonic distortion (THD, TDD and K-Factor) and
individual harmonic measurements.
The C191HM is suitable for mounting on 136x136mm square cut-outs.
Features
Harmonic Measurements
• Individual voltage and current harmonics with harmonic angles up to
order 40.
• Harmonic power direction (through PAS software)
• Synthesized voltage and current waveforms (through PAS software)
Display
The front panel features bright LED displays (three windows, up to 45 pages)
with adjustable display update time. Display auto scroll is available on the main

2 Chapter 1 Introduction
screen with a programmable scroll interval of 2 to 15 seconds. Automatic return
to the main screen is available after 30 seconds of uninterrupted use. The front
panel also includes:
• bar graph showing percentage load with respect to user-definable nominal
(100%) load current
• alarm LED providing a local indication when a predefined alarm condition
appears. The alarm LED is shut off manually (by pressing on both up and
down keys more than 5 sec)
• RXD/TXD LEDs showing communications receive/transmit status
Setup is menu driven, with optional password protection. 16 programmable
setups are provided for alarm and control functions (for programmable
parameters, see ‘Measured Parameters’ below).
Communications are available using an RS-232 or RS-485 standard (factory
set), with ASCII/Modbus (and optional DNP3.0) protocols. 120 user assignable
registers are available in ASCII/Modbus protocols.
Eight relays are provided for energy pulsing (KYZ) or alarm and remote control.
Contacts of six relays may switch loads up to 250V, 5A AC and are
recommended for alarm and remote control; contacts of two relays may switch
loads up to 250V, 3A AC and may be used for energy pulsing.
One optically isolated analog output is provided for remote monitoring or
control. Current loop options are 0-20 and 4-20 mA. The analog output must be
used with an external power supply.
Four counters are provided for counting user-defined events or their duration.
These can be used for counting total operation time of generators or overload
time of transformers or power lines. The counters are operated and released by
user-defined triggers.
One digital input can be used as a status input for monitoring external contacts
or as an external synchronization input for power demand interval
synchronization. When no external synchronization pulse is provided, the power
demand interval can be synchronized through communications.
Three user-selectable options are provided:
Power calculation mode
Energy rollover value
This option specifies the point at which the energy value rolls over to zero.
Phase energy calculations mode
This option is used to enable or disable phase energy calculations.

2.2 Electrical Installation
Before installation ensure that all incoming power sources are shut
OFF. Failure to observe this practice can result in serious or even fatal
injury and damage to equipment.
2.2.1 Power Supply Connection
The power supply can be dedicated-fused, or from a monitored voltage if it is
within the instrument’s power supply range. Use an external circuit breaker or
switch.
AC power supply: line to terminal 12; neutral to terminal 10.
DC power supply: positive to terminal 12; negative to terminal 10.
2.2.2 Current Inputs
Connect the instrument to the current transformer as shown in Figures 2-2
through 2-8.
2.2.3 Ground
Connect the chassis ground C191HM terminal to the switchgear earth ground
using dedicated wire of greater than 2.5 mm2/13 AWG.
2.2.4 Voltage Inputs
Input of 690V (Standard): Use any of the seven wiring configurations shown in
Figures 2-2 through 2-8.
Input of 120V (Option U): 120V input usually implies use of a potential
transformer (PT). The PT requires use of any of the four wiring configurations
shown in Figures 2-4 through 2-7.
