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.
Each option module is sold separately and is installed by the
user, following the details below.
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,
double Insulation. 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.
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 (electro-
magnetic 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.
Specification
Ethernet
The Ethernet modules supports dynamic IP addressing from a
DHCP server. Suitable software can be used to fix the IP address
if necessary. eg. www.chipkin.com

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.
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
