a. Before removing a module, ensure that you are at the same electrostatic potential as the equipment
by touching the case.
b. Handle the module by its front-plate, frame, or edges of the printed circuit board. Avoid touching the
electronic components, printed circuit tracks or connectors.
c. Do not pass the module to any person without first ensuring that you are both at the same
electrostatic potential. Shaking hands achieves equipotential.
d. Place the module on an antistatic surface, or on a conducting surface which is at the same potential
as yourself.
e. Store or transport the module in a conductive bag.
More information on safe working procedures for all electronic equipment can be found in
BS5783 and IEC 147-OF.
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 authorised Dealers.
Misapplication of the above warnings and instruction relieves the Manufacturer of any liability.
2. General
Input currents are supplied to 2 current transformers measuring the earth fault zero-sequence current.
The first (HI = High Input) supplied from terminals 29
– 28 (5A) or 29 – 30 (1A) operates the third
high-set Earth Fault element 3I.
The second (LI = Low Input) supplied from terminals 32
– 31 (5A) or 32 – 33 (1A) operates the first and
the second Low-set Earth Fault elements 1I, 2I.
Taps for 1A and 5A input are provided on relay’s terminal board.
Make electric connection in conformity with the diagram reported on relay's enclosure.
Check that input currents are same as reported on the diagram and on the test certificate.
2.1 - Power Supply
The relay can be fitted with two different types of
power supply
module :
24V(-20%) / 110V(+15%) a.c.
80V(-20%) / 220V(+15%) a.c.
a) -
b) -
24V(-20%) / 125V(+20%) d.c.
90V(-20%) / 250V(+20%) d.c.
Before energising the unit check that supply voltage is within the allowed limits.
