1. General Utilization and Commissioning Directions
Always make reference to the specific description of the product and to the Manufacturer's instruction.
Carefully observe the following warnings.
1.1 - Storage and Transportation
Must comply with the environmental conditions stated in the product's specification or by the applicable
IEC standards.
1.2 - Installation
Must be properly made and in compliance with the operational ambient conditions stated by the
Manufacturer.
1.3 - Electrical Connection
Must be made strictly according to the wiring diagram supplied with the Product, to its electrical
characteristics and in compliance with the applicable standards particularly with reference to human
safety.
1.4 - Measuring Inputs and Power Supply
Carefully check that the value of input quantities and power supply voltage are proper and within the
permissible variation limits.
1.5 - Outputs Loading
Must be compatible with their declared performance.
1.6 - Protection Earthing
When earthing is required, carefully check its effectiveness.
1.7 - Setting and Calibration
Carefully check the proper setting of the different functions according to the configuration of the
protected system, the safety regulations and the co-ordination with other equipment.
1.8 - Safety Protection
Carefully check that all safety means are correctly mounted, apply proper seals where required and
periodically check their integrity.
1.9 - Handling
Notwithstanding the highest practicable protection means used in designing M.S. electronic circuits,
the electronic components and semiconductor devices mounted on the modules can be seriously
damaged by electrostatic voltage discharge which can be experienced when handling the modules.
The damage caused by electrostatic discharge may not be immediately apparent but the design
reliability and the long life of the product will have been reduced. The electronic circuits produced by
M.S. are completely safe from electrostatic discharge (8 kV IEC 255.22.2) when housed in their case;
withdrawing the modules without proper cautions expose them to the risk of damage.
1.10 - Maintenance
Make reference to the instruction manual of the Manufacturer; maintenance must be carried-out by
specially trained people and in strict conformity with the safety regulations.
1.11 - Waste Disposal of Electrical & Electronic Equipment
(Applicable throughout the European Union and other European countries with separate collection
program). This product should not be treated as household waste when you wish dispose of it. Instead,
it should be handed over to an applicable collection point for the recycling of electrical and electronic
equipment. By ensuring this product is disposed of correctly, you will help prevent potential negative
consequence to the environment and human health, which could otherwise be caused by inappropriate
disposal of this product. The recycling of materials will help to conserve natural resource.

1.12 - Fault Detection and Repair
Internal calibrations and components should not be altered or replaced.
For repair please ask the Manufacturer or its authorized Dealers.
Misapplication of the above warnings and instruction relieves the Manufacturer of any liability.
2. General
Input currents are supplied to 8 current transformers: - three measuring phase current side 1 –
three measuring phase current side 2 - one measuring the earth fault zero-sequence current side 1 -
one measuring the earth fault zero-sequence current side 2.
Current input can be selected 1A or 5A by movable jumpers available on relay cards.
The Measuring Ranges of the different inputs are respectively:
Phase Currents
:
(0.02-25)In
Neutral Current
:
(0.005-4)On
Make electric connection in conformity with the diagram reported on relay's enclosure.
Check that input currents and voltages are the same as reported on the diagram and on the test
certificate.
The auxiliary power is supplied by a built-in interchangeable module fully isolated and self protected.
2.1 - Power Supply
The relay can be fitted with two different types of power supply:

24V(-20%) / 110V(+15%) a.c.

80V(-20%) / 220V(+15%) a.c.
Type


24V(-20%) / 125V(+20%) d.c.

90V(-20%) / 250V(+20%) d.c.
Before energizing the unit check that supply voltage is within the allowed limits.
