RECEPTION, HANDLING, INSTALLATION
1.1 Unpackaging
Relays must only be handled by qualified personnel and special care must be taken to protect all
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. 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 device 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. This damage may not be detected, but the electronic circuit reliability and life will be
reduced. The electronic component in the device is well protected by the metal housing, which
should not be removed as the device 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
electrostatic discharges 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 device reliability and the
duration of the life cycle as designed by the manufacturer, 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.

www.fanox.com Rev. 36 7/212
1.4 Installation, commissioning and service
The personnel in charge of installing, commissioning and maintaining this device 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 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 device 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 device 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 device 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
resulting high voltage 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 device, capacitors should be discharged through their 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.
