Chapter 1. Previous steps and precautions
1.1. Initial inspection
Please, check that the contents of the consignment are correct and verify that no element has been
damaged during the transport. In case of mistaken or damaged material, please state an immediate
claim to the transport carrier and notify it immediately to the manufacturer or distributor, either for a
new remittance or for the repair or replacement of the damaged material.
1.2. Safety instructions
All the devices described in this manual have been designed to be properly performed by qualified
technical personnel only. Personnel skilled enough to foresee the possible consequences of
inadequate handling must carry out the installation, setting, maintenance or repair of this equipment.
For a correct and safe use of the provided equipment and in order to achieve the best possible
security conditions, it is essential to follow not only general security procedures but also the special
ones described in this manual.
Never switch on the systems should there be the slightest suspicion of bad functioning.
This may happen as a consequence of damages during storage, transport, etc.
Before any setting or maintenance operations, disconnect the equipment from any power
supply or optical emitter. After electrical disconnection, inside capacitors could remain
loaded for one second.
Active power circuitry could appear when protecting lids or coverings are taken away. Likewise,
unplugged optical connectors must be immediately covered with the corresponding protecting caps.
Should the equipment need to be checked while functioning, remember that maintenance operations
can only be carried out by qualified technical personnel who is aware of the risks of the operation,
both from the electrical and optical point of view.
The security classification of this product is Class III
The modification of the electrical protection elements and the disconnection of the earth terminal
may result in personal injury.
Before the equipment is switched on, make sure that it has been properly grounded (through the
protective conductor of the a.c. power cable) to a socket outlet provided with protective earth contact.
The earth circuit cover of the electrical external connectors must not be used as protective general
earth contact for the equipment.
The optical transmitters could cause safety problems to the personnel in charge of the installation,
test, service or maintenance of the equipment. This is due to the high level of optical power in some
fibre-optic installations and to the fact that light radiation is infrared type (not visible for the human
eye).
As a consequence, never look directly either at the optical output of an optical transmitter, or
at the end of an optical fibre connected to an active optical transmitter. This situation will be
especially dangerous when the inspection takes place with the assistance of light focusing
elements, magnifying glasses, microscopes, etc.
In case these recommendations are not followed, eyes would be exposed to a level of light radiation
that would be higher than the maximum admissible level. This could result in permanent and
irreversible damages in eyes.
The use of controls, adjustments or procedures different from the ones specified here, could cause a
dangerous exposure to radiation.
