Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or included in this document.
2. This product is intended to be used with a three-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 three-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.
