2 Product 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 B
digital device.
Please refer to the Declaration of Conformity.
2.2 Independent Laboratory Testing
This unit has undergone extensive testing according to the European Union Directive and Standards.
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 outdoor area. See certificate and tests of compliance.
EasyGrid Base has been extensively tested to stringent environmental standards to ensure it remains reliable
when used under published specifications.

4.1 ntroducing the EasyGrid Base
The EasyGrid Base fiber optic temperature measurement system is designed for real-time monitoring of
transformer hotspot.
It can be configured to have 4, 6, 8, 10 or 12 channels. Monitors can be daisy chained in serial Modbus mode
to a maximum of 247 units.
Each unit has multiple serial interfaces (1x USB and 1 x RS-48 ) and 1x optional Ethernet communication port.
Standard supported serial communication protocol is MODBUS.
Optional supported Ethernet communication protocols are: IEC-618 0, IEC-60870- -104, DNP3 and TCP-IP
MODBUS.

multiple braid 8 AWG copper wire) to insure adequate protection.

EasyGrid Base User Guide v1.0

4.5 Powering the EasyGrid Base
The EasyGrid Base requires a 24V DC power supply.
The power input terminal block is located at the bottom left of the terminal face panel.
There is no Power Switch per say. As soon as connected, it is energized and powered up.
1. Connect the unit to the power supply using terminal block connectors V+, V-
2. Wire the power input terminal block to a power supply providing the required
voltage and power.
Please refer to the power supply operating guide for important notices and installation
information.
WARN NG
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.
4.6 Optical Connectors
There can be up to 12 optical channels on each EasyGrid Base. Each
channel is designed to be connected with a fibre Optic extension, an
EasyThrough and a Fiber Optic sensor.
CAUT ON
Use care in handling fiber optic connectors. Always clean the fiber tip prior to insertion into
the connector for optimum performance. For details on connector handling and
maintenance, please refer to Cleaning Procedure section.
To connect a ST connector, follow these steps:
1. Remove the protective cap from the Male ST Connector and ST Mating
2. Use the One-Click-Cleaner tool to clean the Male ST connector and the ST Mating
3. Align the male connector key with the mating slot
4. Insert the connector in the mating
. Twist to lock

4.7 Protecti e Dust Caps
This monitor now includes permanently mounted protective
dust caps for each individual optical connector. The cap(s) is
designed to help you keep the connector(s) clean preventing
the dust from accumulating inside when not in use.
The cap(s) just need to be pulled off to uncover the desired
optical connector(s) and left dandling when a sensor is
connected.
It is recommended to always put the protective caps back on
when a channel is not in use and no sensor is connected.

4.9 Analog Outputs
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 Base provides one analog output for each
temperature channel present in the unit.
Wire length and gage 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.
Please refer to Channel Setup and Analog Output Scale section of the Nortech Client II User Guide for detailed
information.
4.10 Connection - USB
The USB configuration port is accessible off the side panel in the lower left section.
The USB port is used to link to a PC for parameter configuration, data retrieval and
firmware update using the Client Software.

connected into the COM port.
The configuration connection can be achieved in one of the 2 following configurations:
Option #1

4.12 Connection – RS-485 / RS-422
A RS-48 / RS-422 serial port is provided on the EasyGrid Base.
It can be used to connect the EasyGrid Base to any RS-48 or RS-422 communication bus.
It also allows multiple EasyGrid Base to be link together off the same communication bus.
The physical port is accessible using the dedicated terminal block.

4.13 RS-485 / RS-422 Network Recommendations
FISO recommends shielded, twisted pair wiring, 24 AWG with 120Ω line impedance to connect the RS-
48 / RS-422 interface to the network.
FISO also recommends biasing the RS-48 BUS using pull-down and pull-up 1 KΩ resistors. Biasing the
RS-48 BUS line will prevent unknown voltage on these lines (RS-48 BUS floating).
Leaving the RS-48 BUS floating may result in conditioner communication failure.
FISO also recommends biasing the RS-48 BUS using pull-down and pull-up 1 KΩ resistors. Biasing the
RS-48 BUS line will prevent unknown voltage on these lines (RS-48 BUS floating).
Leaving the RS-48 BUS floating may result in conditioner communication failure.
You must identify the host device on the RS-48 network and then proceed with its RS-48 BUS line biasing.
Two termination resistors must be installed and have the same characteristic impedance value as the twisted
wire used on the RS-48 network. RS-48 network termination resistors typical values are respectively 120Ω
and ½ Watt.
The only protocol used thru the RS-48
port is MODBUS RTU and it supports
up to 247 nodes over the serial bus.
MPORTANT
When linking more than 1 device together off the same network bus line, make sure that all
units have a different network IDs in order to avoid communication conflicts.
The factory-defined address for all units is one “1”.
