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.
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.
WARNING.
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.
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.
During installation suitable PPE, including eye
protection MUST be worn at all times.
