2Product Certification
2.1 CE Information
Electronic test equipment is subject to the EMC Directive in the European
Union. The EN61326 standard prescribes both emission and immunity
requirements for laboratory, measurement, and control equipment.
This unit has been tested and found to comply with the limits for a Class A
digital device. Contact FISO for access to the Declaration of Conformity.
2.2 Independent Laboratory Testing
This unit has undergone extensive testing according to the European Union Directive and Standards. All
pre-qualification tests were performed internally, at FISO, while final tests were performed externally, at
an independent, accredited laboratory. This guarantees the unerring objectivity and authoritative
compliance of all test results.
Use of shielded remote I/O cables, with properly grounded shields and metal connectors, is
recommended in order to reduce radio frequency interference that may emanate from these cables.
Shielded I/O cables are recommended to improve protection against lightning surge if unit or cables are
installed in an outdoor area. See certificate and tests of compliance.
EasyGrid has been extensively tested to stringent environmental standards to ensure it remains reliable
when used under published specifications.
Contact FISO for any inquiry related to monitor certification.

3.2 Safety Information
The level of radiation from the monitor light sources is below the level known to cause eye injury
through accidental short-term exposure. However, avoid prolonged exposure to light emitted from the
fiber and do not stare directly at any light beam, visible or not.
The following safety instructions must be observed whenever the EasyGrid is operated. Failure to comply
with any of these instructions or with any precaution or warning contained in the Nortech Fiber Optic
Thermometer and Client Software user’s guide is in direct violation of the standards of design,
manufacture and intended uses of the EasyGrid. FISO assumes no liability for the customer failure to
comply with these safety requirements. THIS PRODUCT IS NOT DESIGNED FOR USE IN LIFE SUPPORT OR
CRITICAL HUMAN APPLICATIONS.
In no case will FISO be liable to the buyer, or to any third parties, for any consequential damage or
indirect damage that is caused by product failure, malfunction, or any other problem.
FISO recommends using the qualified power supply available for purchase with your EasyGrid and verify
that the voltage specifications indicated on the power supply are compatible with the AC voltage and
frequency delivered at the power outlet.

EasyGrid User Guide MAN-00084 R 11.0

4First Steps
4.1 Introducing the Nortech EasyGrid
The EasyGrid fiber optic temperature measurement system is designed for real-time monitoring of
transformer hotspots.
It can be configured to have 4 to 18 channels. Modules can be daisy chained to a maximum of 32, which
gives the possibility to have up to 576 channels in a single system. Each unit has multiple serial
interfaces (1 x USB and 1 x RS485) and 1x optional Ethernet communication port. Supported
communication protocols are Nortech and MODBUS (RTU and ASCII). Optional supported
communication protocols are IEC-61850, IEC-60870-5-104, DNP3 and TCPIP-MODBUS, either through an
RJ45 output or an ST optical output.
4.2 Quick Start
4.2.1 Powering the EasyGrid
The EasyGrid requires 24 volts DC (± 10%) power. The power input terminal block is coloured orange for
additional visual aid.
WARNING
Make sure to have a power supply providing the specified power and compatible with your local
power outlet
Power Input
ON/OFF Switch

1. Make sure that the power switch is OFF when connecting the power supply to the unit.
2. Wire the power input terminal block to a power supply providing the required voltage and
respect connector polarity.
3. Power up the unit using the ON/OFF switch located on the panel above the relay terminal block.
4.2.2 Connecting Temperature Sensors
The EasyGrid is compatible with all FISO TPT-62 sensors. No calibration factor or calibration procedure is
required to get accurate temperature measurements.
1. Remove the protective cap from the Male ST Connector and ST Mating
2. Using the One Click tool clean the Male ST connector and the ST Mating
3. Align the male connector alignment key with the mating slot.
4. Insert ceramic ferrule of the Male ST connector in the ST Mating
5. After making sure it is properly inserted, Push and Twist to lock the spring loaded ring to the ST
Mating

4.2.3 Reading Temperature Measurements
With the power switch to ON and sensors connected you can read the temperature of each sensor on
the EasyGrid display, up to 18 channels at one time, as displayed below.
For more information on FISO system characteristics, maintenance and installation, refer to document
MAN-00098 Nortech System Installation User Guide.

5.6 Action Buttons or State Icons
To help during navigate through the various Settings and Monitoring displays, one basic interface
information is important to know.
Contoured round knobs, for example , are Action Buttons; they allow parameter modification or
function selection.
Round knobs without contour, for example , are State Icons; they simply provide information on the
state of the related parameter or function.
5.7 Communication and System Status LED

5.8 USB Configuration Port
The USB configuration interface is accessible in the maintenance panel.
The port serves two purposes:
Communicating with a PC through Nortech Client Software to configure the EasyGrid monitor
parameters, retrieve stored data, upload data or operate the EasyGrid monitor.
Upload updated version of the firmware.

5.9 Power Input
The EasyGrid accepts only 24 volts DC (± 10%), 40W.
WARNING
To avoid damage to the unit, make sure that the power fed into the input complies with technical
specifications. No other voltage level or range is accepted.
Connect the unit to the power supply using terminal block connectors 24VDC and ground.
Please refer to your power-supply operation manual for important notices and
installation information.
5.10 Power Switch
The power ON/OFF switch is located above the relay terminal blocks
Once all wires are connected, press Ion the switch to power ON the unit. To
power OFF, press the Oon the switch.

EasyGrid User Guide MAN-00084 R 11.0

5.11 Analog Output
Each analog output offers a standard 4-20 mA factory configuration.
Analog outputs provide a means of transmitting temperature data directly
from the unit to an external data-gathering system or monitoring
equipment. The EasyGrid provides one output for each temperature channel
present in the unit.
Wire length and gauge are related when connecting analog outputs. For a
run of 100 m or less, recommended gage is 24 AWG or greater. The longer
the run, the smaller the recommended gage will be. Recommendations call
for shielded wire, or for installation in a metal conduit.

5.12 RS-485/RS-422 Ports
A RS-485/RS-422 serial port is provided on the EasyGrid. It can be used to connect the EasyGrid to any
RS485 or RS422 communication bus. It also allows multiple EasyGrid monitors to be link together.
IMPORTANT
When linking many EasyGrid monitors on the same party line, make sure that all units have a different
network ID. The factory-defined address for all units is one (1).
The port is accessible using the dedicated terminal block. The pin layout is the following
A set of dip switches are used to configure the port. They are located behind the access plate on the
right of the screen

FISO recommends shielded, twisted pair wiring, 24 AWG with 120Ω line impedance to connect the RS-
485 interface to the network.
FISO also recommends biasing the RS-485 BUS using pull-down and pull-up 1 KΩresistors. Biasing the
RS-485 BUS line will prevent unknown voltage on these lines (RS-485 BUS floating). Leaving the RS-485
BUS floating may result in NORTECH conditioner communication failure.
You must identify the host device on the RS-485 network and then proceed with its 485 BUS line biasing,
as shown above.
Two termination resistors must be installed and have the same characteristic impedance value as the
twisted wire used on the 485 network. RS485 network termination resistors typical values are
respectively 120Ω and ½ Watt.
In Nortech mode, it is possible to connect up to 32 units together. When all units are connected on the
same RS-485 bus, this allows a user to execute the software configuration from a single USB port.
In MODBUS mode, it is possible to connect up to 247 units.
