Firefly Safety Requirements
IMPORTANT SAFETY INSTRUCTIONS:
The following safety instructions apply to Visual Circuits
Corporation Firefly:
1. Read and follow all warning notices and instructions marked on the
product or included in this manual. Opening or removing covers and/
or components may expose you to dangerous high voltage points or
other risks. Qualified personnel should perform all servicing.
2. The maximum ambient temperature for the Firefly is 114 degrees
Fahrenheit (45 degrees Celsius). Care should be given to allow
sufficient air circulation or space between units when Firefly is
installed in a closed or multi-unit rack assembly because the
operating ambient temperature of the rack environment must be
greater than room ambient temperature.
3. Slots and openings in the cabinet (chassis) are provided for
ventilation. To ensure reliable operation of the product and to protect
it from overheating, maintain a minimum of 1-inch (2.5-cm)
clearance on the top and sides.
4. Installation of the Firefly in a rack without sufficient airflow can be
unsafe.
5. If installed in a rack, the rack should safely support the combined
weight of all equipment it supports. A fully loaded Firefly weighs 12
pounds (4.6 kg).
6. The connections and equipment of the Firefly should be capable of
operating safely with the maximum power requirements of the
Firefly. In the event of a power overload, the supply circuits and
supply wiring should not become hazardous.
7. Models with AC power inputs are intended to be used with the three-
wire grounding type plug (a plug that has a grounding pin). This is a
safety feature. Equipment grounding is vital to ensure safe operation.
Do not defeat the purpose of grounding type plugs by modifying the
plug or using an adapter.
8. If a three-wire grounding type power source is not available, consult
a qualified electrician to determine another method of grounding the
equipment.
9. Install only in restricted areas in accordance with Articles 110-16,
100-17 and 110-18 of the National Electrical Code, ANSI/NFPA 70.
