Introduction
The Integra, INT-2270 and Integra INT-2170, are a multifunction digital meter for the measurement of power quality. They provide measurement isolation and conversion of all main electrical parameters. Both INT-2270 and INT-2170 can be used in single and three-phase balanced or unbalanced, 3 or 4 wire electrical systems.
The INT-2270 has an accuracy of CL0.2S.
The INT-2170 has an accuracy of CL0.5S.
Both include RS485 Modbus RTU communications protocol and Pulse/Alarm input/outputs as standard.
Measurement
The device is supplied programmed to the users requirements but can be easily reprogrammed to suit any application.
Setup
The Integra, INT-2*70, is individually calibrated to full accuracy. No further adjustments or setup is required.
Should the unit need reprogramming please refer to the Programming Guide for further information.
Warnings
Risk of Electric Shock
- 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.
- During installation suitable PPE, including eye protection MUST be worn at all times.
Safety
The unit is designed in accordance with BS EN 61010-1:2001 (IEC 61010-1:2001) – Permanently connected use, Normal condition. Installation category III, pollution degree 2, basic insulation for rated voltage. Measurement Category III.
Maintenance
In normal use, no maintenance is needed. As appropriate for service conditions, isolate from electrical power, inspect the unit, and remove any dust or other foreign material present. Periodically check all connections for freedom from corrosion and screw tightness, particularly if vibration is present.
The front of the case should be wiped with a dry cloth only. Use minimal pressure, especially over the viewing window area. If necessary wipe the rear case with a dry cloth. If a cleaning agent is necessary, isopropyl alcohol is the only recommended agent and should be used sparingly. Water should not be used. If the rear case exterior or terminals should be contaminated accidentally with water, the unit must be thoroughly dried before further service. Should it be suspected that water might have entered the unit, factory inspection and refurbishment is recommended.
It is essential that the primary current is isolated BEFORE connecting or disconnecting the secondary current connections
The unit is intended for panel mounting. Avoid mounting the unit where there is excessive vibration; in excessive direct sunlight; or outside a reasonably stable ambient temperature.

EMC Installation Requirements
Whilst this unit complies with all relevant EU EMC (electromagnetic compatibility) regulations, any additional precautions necessary to provide proper operation of this and adjacent equipment will be installation dependent and so the following can only be general guidance:
- Avoid routing wiring to this unit alongside cables and products that are, or could be, a source of interference.
- The supply to the unit should not be subject to excessive interference. In some cases, a supply line filter may be required.
- To protect the product against incorrect operation or permanent damage, surge transients must be controlled. It is good EMC practice to suppress transients and surges at the source. The unit has been designed to automatically recover from typical transients; however in extreme circumstances it may be necessary to temporarily disconnect the supply for a period of greater than 10 seconds to restore correct operation.
- Screened communication leads are recommended and may be required. These and other connecting leads may require the fitting of RF suppression components, such as ferrite absorbers, line filters etc., if RF fields cause problems.
- It is good practice to install sensitive electronic instruments that are performing critical functions in EMC enclosures that protect against electrical interference causing a disturbance in function.
Wiring
Connections are made via shrouded screw-clamp 0.05-4mm wire. Choice of cable should meet local regulations for the operating voltage.
Connector plugs are suitable for copper wires only and will accept one stranded 0·05 – 4mm2 (30 - 11AWG) stranded core cables. This instrument is intended for panel mounting. Terminals must be enclosed within the panel. For mains terminals use wire rated at 1000V, 60°C minimum temperature. Terminal screws are fully tightened for shipment and must be undone before wire insertion. Terminal screws should be tightened to 0·5 Nm (4·4 lbf in) only.
Fusing
This unit must be installed with external fuses in the voltage supply lines of type slow blow 1A maximum. Choose fuses of a type and with a breaking capacity appropriate to the supply and in accordance with local regulations.
A suitable switch or circuit breaker conforming to the relevant parts of IEC 60947-1 and IEC 60947-3 should be included in the installation. It should be positioned so as to be easy to operate, in close proximity to the equipment, and clearly identified as the disconnecting device.
