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 a UL-listed or
CSA-certified power source with a Class 2 or Limited Power Source (LPS) output. Input
power to the dc voltage configurations of this product must be provided by a National Electric
Code (NEC) or a Canadian Electric Code (CEC) Class 2 circuit.
10. This product contains a coin cell lithium battery that is only to be replaced at the factory.
Caution: There is a danger of explosion if the battery is incorrectly replaced. Replace only
with the same type. Dispose of used batteries according to the battery manufacturer’s
