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 0.1A Current Transformers and can be
used 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 1221 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 secondary current is 0.1A. The CT Primary value should be
set according to the CT. It can be used on primary currents up to 9999A. e.g.
For a 250/0.1A CT. CT2 = 0.1, 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.

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 1221 has Two Pulsed Outputs. One pulsed output is configurable
to active (kWh) or reactive (kVArh) energy. The second pulsed output is fixed to

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.
