Installation Tips
WARNING!
Only authorized service personnel should attempt to install
and/or repair this equipment. All problem discovery and repair procedures
are detailed to allow only sub-assembly or module level repair. Due to the
complexity of design, no one should attempt to make repairs at the
component level or make modifications to any circuit board. Improper
repairs can create a safety hazard.
Follow these tips when installing the ONT:
y
Keep fiber optic cables and splicing equipment clean at all times. Use manufacturer
approved solvents and cleaning applicators. For more detailed information on Fiber
Optic Cable installation and maintenance,
see Chapter 4
y
Take care to use the proper connectors for the application. Mismatching connectors
or the use of the wrong type of connector can result in the loss of optical power and
damage to the connectors. It is absolutely critical that the ONT is connected to a
known good earth ground. Failure to properly ground the unit during installation will
cause loss of services.
Important:
Installations which utilize off-premises telephone extensions must also
incorporate a primary ground protection device for each off premises instance.
WARNING!
This device does not incorporate a primary protector. If off
premises coax or telephone cable lengths exceed 140 feet (42.7 m), a
listed primary protector is required per the National Electric Code.
y
When routing optic fibers, be careful to avoid bending the fibers beyond the
manufacturer recommended 1” (2.54 cm) bend radius. Exceeding the bend radius can
cause excess attenuation and possibly break the fiber.
y
Verify all optical power levels before connections are made. If excessive loss is noted,
the use of an optical time domain reflectometer (OTDR) may be required.
y
Clean the fiber ends before making any connections.
ALERT!
A Class I laser product is used in this equipment. Use an
optical power meter to identify active fibers. Never assume laster
power is turned off or that the fiber is disconnected at the other end.
A protective cap or hood must be place over any radiating bulkhead
receptacle or optical fiber connector.
Important:
If grommets are inadvertently removed during the installation process, make
certain you reseal these openings prior to leaving the site. Openings in the ONT housing
can invite insects or rodents to nest inside the unit creating service delivery problems in
the future.
y
The electronics inside the Model 560 housing can be sensitive to electrostatic
discharge. Use of a static wrist strap is required.
