Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or included in the manual.
2. The power supply for 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. Input power to this product must be provided by one of the following:
—
A UL Listed/CSA Certified power supply with a Class 2 or Limited Power Source (LPS) output for use in North
America.
—
A Certified power supply with a Safety Extra Low Voltage (SELV) output for use in the country of installation,
having a maximum 240 VA available.
4. 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.
5. Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the

agencies and inspection authorities to ensure compliance.
9. 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.
