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 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 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

The main features of the relays are:

User friendly front face with hi-resolution graphic display (240x128), 10 programmable signal Leds, 6 push-

buttons (configurable) and four push-button for complete local managemen, USB for local communication.

Eight user programmable Output Relays.

Eight opto-isolated, self powered Digital Inputs.

Additional RS485 communication port

Input currents are supplied to 3 current transformers: measuring phase currents.

An additional internal CT directly measures the residual (Zero Sequence) current of the three inputs.

Current inputs can be 1 or 5A: selection between 1A or 5A is made by movable jumpers provided inside the

Relay.

2.1 - Power Supply

The relay can be fitted with two different types of power supply:

Type 1

24V(-20%) / 110V(+15%) a.c.

24V(-20%) / 125V(+20%) d.c.

Type 2

80V(-20%) / 220V(+15%) a.c.

90V(-20%) / 250V(+20%) d.c.

Before energizing the unit check that supply voltage is within the allowed limits.
