1. Be sure to read and follow all warning notices and instructions.
2. The maximum recommended ambient temperature for the PES-1014 is 50º Celsius. Care must be taken to allow
sufficient air circulation or space between units when the PES-1014 is installed inside a closed rack assembly.
The operating ambient temperature of the rack environment might be greater than room temperature.
3. Installation in a rack without sufficient airflow can be unsafe.
4. Racks should safely support the combined weight of all equipment.
5. The connections and equipment that supply power to the PES-1014 should be capable of operating safely with
the maximum power requirements of the PES-1014. In case of a power overload, the supply circuits and supply
wiring should not become hazardous. The input rating of the PES-1014 is printed on the nameplate.
6. The power cord must plug in to the right supply voltage, i.e. 110VAC for North America and 230VAC for
Europe. Make sure that the supplied AC voltage is correct and stable.
7. Installation in restricted access areas must comply with Articles 110-16, 110-17, and 110-18 of the National
Electrical Code, ANSI/NFPA 70.
8. Do not allow anything to rest on the power cord and do not locate the product where anyone can walk on the
power cord.
9. Do not service the product by yourself. Opening or removing covers can expose you to dangerous high voltage
points or other risks. Refer all servicing to qualified service personnel.
10. Generally, when installed after 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 the
appropriate regulatory agencies and inspection authorities to ensure compliance.
11. A rare condition can create a voltage potential between the earth grounds of two or more buildings. If products
installed in separate building are interconnected, the voltage potential can cause a hazardous condition. Consult
a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action before interconnecting the products. If the equipment is to be used with
telecommunications circuit, take the following precautions:
Never install or modify telephone wiring during a lightning storm.
Never install telephone jacks in a wet location unless the jack is specially designed for use in wet locations.
Never touch uninsulated (bare) telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
