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. 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.
