1 RECEPTION, HANDLING & INSTALLATION
1.1 Unpacking
Relays must only be handled by qualified personnel and special care must be taken
to protect all of their parts from any damage while they are being unpacked and
installed. The use of good illumination is recommended to facilitate the relay visual
inspection.
The facility must be clean and dry, and relays should not be stored in places that are
exposed to dust or humidity. Special care must be taken if construction work is taking
place.
1.2 Reception of relays
It is necessary to inspect the relay at the time it is delivered to ensure that the
relays have not been damaged during transport.
If any defect is found, the transport company and Mevoco should be informed
immediately. If the relays are not for immediate use, they should be returned to their
original packaging.
1.3 Handling electronic relay
Relays contain an electronic component that is sensitive to electrostatic discharges.
Just by moving, a person can build up an electrostatic potential of several thousand
volts. Discharging this energy into electronic components can cause serious damage
to electronic circuits. It is possible that this damage may not be detected straight
away, but the electronic circuit reliability and life will be reduced. This electronic
component in the relay is well protected by the metal housing, which should not be
removed as the relay cannot be adjusted internally.
If it is necessary to disassemble the electronic component, this must be carried out
with care and contact with electronic components, printed circuits and connections
must be avoided to prevent an electrostatic discharge that could damage one of the
components. If the electronic components are stored outside the metal housing, they
must be placed in an antistatic conductive bag.
If it is necessary to open a module, care must be taken to preserve the relay
reliability and the duration of the life cycle as designed by the manufacturer by taking
the following actions
● Touch the housing to ensure that you have the same potential
● Avoid touching the electronic components and handle the module by its
edges.
● Remember that everyone who handles the module must have the same
potential.
● Use a conductive bag to transport the module.
For more information about how to handle electronic circuits, consult official
documents such as the IEC 147-OF
7
!
1.4 Installation, commissioning and service
The personnel in charge of installing, commissioning and maintaining this relay must
be qualified and must be aware of the procedures for handling it. The product
documentation should be read before installing, commissioning or carrying out
maintenance work on the relay.
Personnel should take specific protection measures to avoid the risk of electronic
discharge when access is unlocked on the rear part of the relay.
In order to guarantee safety, the crimp terminal and a suitable group tool must be
used to meet isolation requirements on the terminal strip. Crimped terminations must
be used for the voltage and current connections.
It is necessary to connect the relay to earth through the corresponding terminal,
using the shortest possible cable. As well as guaranteeing safety for the personnel,
this connection allows high frequency noise to be evacuated directly to earth.
The following checks must be performed before the relay is supplied:
● The rated voltage and polarity.
● The power rating of the CT circuit and the integrity of the connections.
● The integrity of the earth connection.
The relay must be used within the stipulated electrical and environmental limits.
Note: Regarding the current transformer circuits: Do not open a live CT secondary
circuit. The high voltage produced as a result could damage the isolation and
threaten lives.
1.5 Storage
If the relays are not going to be installed immediately, they must be stored in a dust-
and humidity free environment after the visual inspection has been performed.
1.6 Recycling
Before recycling the relay, the capacitors should be discharged through the external
terminals. All electrical power sources should be removed before performing this
operation to avoid the risk of electrical discharge.
This product must be disposed of in a safe way. It should not be incinerated or
brought into contact with water sources like rivers, lakes, etc.
Fanox Electronic, S.L. adheres itself to the 1st additional disposal of the Spanish
11/97 Standard in which it is said that the final user of the containers should give
them, properly segregated by materials, to an authorized recovery, recycler or valuer
company.
