Required Equipment
The cables needed to connect to the PL-1000RO depend on the PL-1000RO
application. You can use standard cables or prepare the appropriate cables
yourself (see
2.3.3
Cable Connections
Before starting, refer to the site installation plan and identify the cables intended
for connection to this PL-1000RO unit (see
) and
2.3.3.1
Optical Cable Handling Precautions
The following are the optical cable handing precautions:
•
Make sure that all the optical connectors are closed at all times, either by the
appropriate protective caps or by the mating cable connector. Do not remove
the protective cap until an optical fiber is connected to the corresponding
connector, and immediately install a protective cap after a cable is
disconnected.
•
(Recommended) Before installing optical cables, thoroughly clean their
connectors using an approved cleaning kit.
•
When connecting optical cables, make sure to prevent cable twisting and
avoid sharp bends. Unless otherwise specified by the optical cable
manufacturer, the minimum fiber bending radius is 35 mm. Always leave
some slack, to prevent stress.
•
(Recommended) Install plastic supports on each cable connector. These
supports determine the fiber bending radius at the connector entry point and
also prevent stress at this point.
2.3.3.2
Connecting the PL-1000RO to Ground and Power
W
ARNING
:
Any interruption of the protective (grounding) conductor (inside
or outside the device) or disconnecting the protective earth terminal can make
the device dangerous. Intentional interruption is prohibited.
G
ROUNDING
:
The PL-1000RO protective ground terminals must be connected to protective
ground before power is applied and before connecting any other cable. This
connection is made through the AC or DC power cable.
The power cord plug should only be inserted in an outlet provided with a
protective ground (earth) contact. The protective action must not be negated
by using an extension cord (power cable) without a protective conductor
(grounding).
