Read and follow all warning notices and instructions marked on the product or included in the
manual.
This product is intended to be used with a 3-wire grounding type plug – a plug which has a
grounding pin. This is a safety feature. Equipment grounding is vital to ensure safe operation.
Do not defeat the purpose of the grounding type plug by modifying the plug or using an
adapter.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for the
presence of earth ground. If the receptacle is not properly grounded, the installation must not
continue until a qualified electrician has corrected the problem.
If a 3-wire grounding type power source is not available, consult a qualified electrician to
determine another method of grounding the equipment.
The dc configuration of this product is to be grounded by connecting an external wire
between the building ground and the equipment ground screw on the rear of the power supply
assembly. Consult a qualified electrician to ensure that the ground connections are connected.
Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of
the product and to protect it from overheating, these slots and openings must not be blocked
or covered.
Do not allow anything to rest on the power cord and do not locate the product where persons
will walk on the power cord.
Do not attempt to service this product yourself, as opening or removing covers may expose
you to dangerous high voltage points or other risks. Refer all servicing to qualified service
personnel.
General purpose cables are provided with this product. Special cables, which may be required
by the regulatory inspection authority for the installation site, are the responsibility of the
customer.
Install carriers while still empty. Start at the bottom of the cabinet and work up.
When installed in the final configuration, the product must comply with the applicable Safety
Standards and regulatory requirements of the country in which it is installed. If necessary,
consult with the appropriate regulatory agencies and inspection authorities to ensure
compliance.
A rare phenomenon can create a voltage potential between the earth grounds of two or more
buildings. If products installed in separate buildings are interconnected, the voltage potential
may cause a hazardous condition. Consult a qualified electrical consultant to determine
whether or not this phenomenon exists and, if necessary, implement corrective action prior to
interconnecting the products.
following precautions:
– Never install telephone wiring during a lightning storm.
– Never install telephone jacks in wet locations unless the jack is specifically designed for
wet locations.
– Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
– Use caution when installing or modifying telephone lines.
– Avoid using a telephone (other than a cordless type) during an electrical storm. There may
be a remote risk of electric shock from lightning.
– Do not use the telephone to report a gas leak in the vicinity of the leak.
