Important Instructions

Important Safety Instructions

1. Read and follow all warning notices and instructions marked on the product or included in the

manual.

2. When an ac power source is used, 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 may be 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. Input power to the ac voltage configuration of this product must be provided by one of the

following: (1) a UL Listed/CSA certified power source with a Class 2 or Limited Power

Source (LPS) output for use in North America, or (2) a certified power source with a Safety

Extra Low Voltage (SELV) output for use in the country of installation.

Input power to the dc voltage configurations of this product must be provided by one of the

following: (1) a National Electric Code (NEC)/Canadian Electric Code (CEC) Class 2 circuit

for use in North America, or (2) a certified Safety Extra Low Voltage (SELV) circuit input for

use in the country of installation.
