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 equipment 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 equipment 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 FANOX should be informed immediately.
If the relays are not for immediate use, they should be returned to their original packaging.
1.3. Handling electronic equipment
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 equipment is well protected by the metal housing, which
should not be removed as the equipment 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 equipment 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.

1.4. Installation, commissioning and service
The personnel in charge of installing, commissioning and maintaining this equipment 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 equipment.
Personnel should take specific protection measures to avoid the risk of electronic discharge when
access is unlocked on the rear part of the equipment.
In order to guarantee safety, the crimp terminal and a suitable 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 equipment 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 equipment 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 equipment 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 equipment, 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…
