ATTENTION invisible Optical Radiation!
If connected to a
power supply, the unit provides invisible Laser-radiation. The source is class 3R Laser diode
as defined in DIN EN 60825-1:2001-11. P0=2mW, Lambda=1310nm.
Never look into fibre-optical components like connectors or fibres. Use an infrared
viewer, optical power meter or fluorescent screen for optical output verification.
Do not allow any dirt or foreign material to get into the optical connector bulkheads. This
may cause damage to the polished optical connector end faces
Follow standard Electrostatic Discharge (ESD) procedures when handling a the chassis and
the modules of the LFTRX.
Select and apply the appropriate 924DC voltage according to the data sheet and
documentation before connecting power.
Install suitable overvoltage protection to ensure that no overvoltage (such as that caused by
a bolt of lightning) or overcurrent can reach the product. Otherwise, the person operating
the product will be exposed to the danger of an electric shock.
The LFTRX can be damaged if the total RF input power is higher than +10dBm specified
maximum value. Do not connect equipment where the total output power is higher than the
specified value of the data sheet or indicated on the LFTRX unit.
In case of a failure do not open the sat-nms LFTRX, you will loose warranty, call SatService
GmbH for a RMA number.
Observe normal safety precautions when operating, servicing, and troubleshooting this
equipment.
Take standard safety precautions with hand and/or power tools.
When connecting the units fault relay circuits, observe the maximum ratings: 24V D/C 50mA.
2.2 Handling instructions for optical connectors
Do not allow any kind of dust or dirt on the fibre.
Do not touch the fibre! Otherwise you will get optical attenuation and the opposite fibre in the
corresponding connector will be contaminated as well.
When installing or changing optical connections, ensure that the environment of the room
where the unit is installed is as dust-free as possible.
If you install the unit on-site, make sure that the complete work that causes dust (e.g.
plastering or concreting) is already finished and the resulted dust is cleaned up properly.
Remove the fibre protection cap of FC/APC connectors just before you connect the optical
connector.
Store the protection caps in a closable box that is absolutely dirt- and dust-free.
After disconnecting a fibre, put a dirt- and dust-free protection cap into the connector in
order to avoid dust contamination.
Before connecting, we strongly recommend to clean the fibre. We recommend to use clean
compressed air spray like e.g. 'Kontakt 334' or a special cleaning device like e.g. 'CLETOP'
or 'one click cleaner'. Do not use compressed air produced by a standard air compressor,
this air is not clean enough! If a dirty fibre (e.g. contaminated with dust) is connected to a
LFTRX unit, the internal fibre of the LFTRX unit will be contaminated as well and you will get
optical attenuation. In the worst case, the fibre-end might be irreparably damaged and has to
