General
The safety information contained in this section, and on
other pages of this manual, must be observed whenever this
unit is operated, serviced, or repaired. Failure to comply with
any precaution, warning, or instruction noted in the manual
is in violation of the standards of design, manufacture, and
intended use of the unit.
Installation, adjustment, maintenance and repair of this
equipment are to be performed by trained personnel aware of
the hazards involved. For correct and safe use of the
equipment and in order to keep the equipment in a safe
condition, it is essential that both operating and servicing
personnel follow standard safety procedures in addition to the
safety precautions and warnings specified in this manual, and
that this unit be installed in locations accessible to trained
service personnel only.
Siqura assumes no liability for the customer’s failure to
comply with any of these safety requirements.
UL/IEC/EN
60950-1: General safety requirements
The equipment described in this manual has been
designed and tested according to the UL/IEC/EN 60950-1
safety requirements.
If there is any doubt regarding the safety of the equipment, do
not put it into operation.
This might be the case when the
equipment shows physical damage or is stressed beyond
tolerable limits (e.g. during storage and transportation).
Before opening the equipment, disconnect it from all power
sources.
The equipment must be powered by a SELV
*)
power
supply.
When this unit is operated in extremely elevated temperature
conditions, it is possible for internal and external metal
surfaces to become extremely hot.
Optical safety
This optical equipment contains Class 1M lasers or LEDs
and has been designed and tested to meet IEC 60825-
1:1993+A1+A2 and IEC 60825-2:2004 safety class 1M
requirements.
Optical equipment presents potential hazards to testing and
servicing personnel owing to high levels of optical radiation.
When using magnifying optical instruments, avoid looking
directly into the output of an operating transmitter or into the
end of a fiber connected to an operating transmitter, or there
will be a risk of permanent eye damage
.
Precautions should
be taken to prevent exposure to optical radiation when the
unit is removed from its enclosure or when the fiber is
disconnected from the unit. The optical radiation is invisible
to the eye.
Use of controls or adjustments or procedures other than
those specified herein may result in hazardous radiation
exposure.
The installer is responsible for ensuring that the label
depicted below (background: yellow; border and text: black)
is present in the restricted locations where this equipment is
installed.
The locations of all optical connections are listed in the
Indications and Connectors section of this manual.
Optical outputs and wavelengths are listed in the Technical
Specifications section of this manual.
