Important Safety Instructions
1
Read and follow all warning notices and instructions marked on the product or included in
the manual.
2
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.
3
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.
4
Do not allow anything to rest on the power cord and do not locate the product where persons
will walk on the power cord.
5
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.
6
General purpose cables are provided with this product. A UL Listed/CSA Certified,
minimum No. 26 AWG, telecommunications cable is provided for connection to the
network. Use this cable to reduce the risk of fire.
Special cables, which may be required by the regulatory inspection authority for the
installation site, are the responsibility of the customer.
7
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.
8
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.
9
In addition, if the equipment is to be used with telecommunications circuits, take the
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.
