Safety

Take notice of the safety guidelines laid out in Chapter 6, Safety Precautions. These are specified in multiple languages.

Power

Make sure that the power source circuits are properly grounded and then use the power cord supplied with the appliance to connect it to the power source.

Using Other Power Cords

If your installation requires a different power cord than the one supplied with the appliance, be sure to use a cord displaying the mark of the safety agency that defines the regulations for power cords in your country. Such marks are an assurance that the cord is safe.

Power Overload

Ensure that the appliance does not overload the power circuits, wiring and over-current protection.

To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the appliance and compare the total with the rating limit for the circuit. The maximum ratings for the 300 Series are listed in Appendix A, NetShield 300 Series Specifications.

Surge Protection

A third party surge protection device should be considered and is strongly recommended as a means to prevent electrical surges reaching the appliance. This is mentioned again in Section 2.5, Connecting Power.

Temperature

Do not install the appliance in an environment where the ambient temperature during operation might fall outside the specified operating range. This range is documented in Appendix A, NetShield 300 Series Specifications.

The intended operating temperature range is "room temperature". That is to say, the temperature most commonly found in a modern office and in which humans feel comfortable. This is usually considered to be between 20 and 25 degrees Celsius (68 to 77 degrees Fahrenheit). Special rooms for computer equipment may use a lower range and this is also acceptable.

Airflow

Make sure that airflow around the appliance is not restricted.

Dust

Do not expose the appliance to environments with elevated dust levels.
