User Manual
Integra 1222
Panel Mounted Energy Meter
for Single and Three Phase
Electrical Systems
1 Introduction
This document provides operating, maintenance and installation instructions.
This unit measures and displays the characteristics of Single Phase Two Wire
(1P2W), Three Phase Three Wire (3P3W) and Three Phase Four Wire (3P4W)
networks. The measuring parameters include Voltage (V), Current (A),
Frequency (Hz), Power (kW/KVA/KVAr), Power Factor (PF), Imported, Exported
and Total Energy (kWh/kVArh). The unit also measures Maximum Demand
Current and Power, this is measured over preset periods of up to 60 minutes.
This particular model accommodates 1A or 5A Current Transformers and can
be configured to work with a wide range of CTs. It also comes with a complete
communications capability with built in Pulse and RS485 Modbus RTU outputs,
configuration is password protected. This product is self-powered from any
phase of the supply.
1.1 Unit Characteristics
The Integra 1222 can measure and display:
• Phase to Neutral Voltage and THD% (Total
Harmonic Distortion) of all Phases
• Line Frequency
• Current, Maximum Demand Current and Current
THD% of all Phases
• Power, Maximum Power Demand and Power Factor
• Imported, Exported & Total Active Energy
• Imported, Exported & Total Reactive Energy
The unit has a Password-Protected set up menu for:
• Changing the Password
• System Configuration - 1P2W, 3P3W, 3P4W.
• Demand Interval Time
• Reset for Demand Measurements
• Pulsed Output Duration
1.2 Current Transformer Primary Current
This unit requires configuring to operate with the appropriate current
transformer(s), the optional secondary currents are 1A or 5A. It is programmed
by inputting the CT Primary value. It can be used on primary currents up to
9999A. e.g. For a 250/5A CT. CT2 = 5, CT1 = 250
On the MID Version, you can only program the CT multiplier ONCE.
This cannot be overridden and must be returned to the factory.
1.3 RS485 Serial – Modbus RTU
This unit is compatible with remote monitoring through RS485 Modbus RTU.
Set-up screens are provided for configuring the RS485 port.
1.4 Pulsed Outputs
The Integra 1222 has Two Pulsed Outputs. One pulsed output is configurable
to active (kWh) or reactive (kVArh) energy. The second pulsed output is fixed to
3200imp/kWh.
2 Start Up Screens
The first screen lights up all display
segments and can be used as a display
check.
The second screen indicates the firmware
installed in the unit and its build number.
Please note: The numbers on the product
may vary from those shown here.
The interface performs a self-test and
indicates the result if the test passes.
*After a short delay, the screen will display active energy measurements.
3 Measurements
The buttons operate as follows:
Selects the Power, Voltage, Current, Energy per phase and the system
values.
In Setup Mode, this is “Escape” (hold 3 sec) button.
Selects the Voltage and Current display screens.
In Setup Mode, this is the “Left” (press) button.
Select the Frequency and Power factor display screens.
In Setup Mode, this is the “Up” (press) button.
Select the Power display screens.
In Setup Mode, this is the “Down” (press) button.
Select the Energy display screens.
In Setup mode, this is the “Right” (press) or “Enter” (hold 3 sec) button.
3.1 Phase and System

Warnings
During normal operation, voltages hazardous to life
may be present at some of the terminals of this unit.
At voltages below that specified in the Range of Use
the meter may shut down. However, voltages
hazardous to life may still be present at some of the
terminals of this unit.
Installation and servicing should be performed only by
qualified, properly trained personnel abiding by local
regulations.
Ensure all supplies are de-energised before attempting
connection or other procedures.
Terminals should not be user accessible after
installation and external installation provisions must
be sufficient to prevent hazards under fault conditions.
This unit is not intended to function as part of a system
providing the sole means of fault protection - good
engineering practice dictates that any critical function
be protected by at least two independent and diverse
means.
The unit does not have internal fuses therefore external
fuses must be used for protection and safety under
fault conditions.
Never open-circuit the secondary winding of an
energized current transformer.
This product should only be operated with the CT
secondary connections earthed.
If this equipment is used in a manner not specified by
the manufacturer, protection provided by the
equipment may be impaired.
