Setup
Selecting a Site
The system operates reliably in a typical office
environment. Choose a site that is:
■
Near grounded, three-pronged power outlets.
Note: For the United States and Canada, this
means a NEMA 5-15R outlets for 100-120 VAC or
NEMA 6-15R outlets for 200-240 VAC. For other
international sites, this means three-pronged power
outlets applicable for the electrical code of the
region.
CAUTION: Be sure the power service connection is
through a properly grounded outlet.
Each power cord can be plugged into a separate
phase of a main AC supply, assuming the circuit is
rated for that load.
Note: For Denmark, the system must be connected
to an AC power source rated at 16 Amps.
■
Clean, dust-free, and well ventilated. Front and
rear ventilating openings kept free of obstructions.
Away from sources of heat, vibration or physical
shock
■
Isolated from strong electromagnetic fields and
electrical noise produced by electrical devices (such
as air conditioners, large fans, large electric motors,
radio and TV transmitters, and high-frequency
security devices)
■
Spacious enough to provide at least five inches (13
centimeters) behind the system and three inches
(eight centimeters) on each side of the system for
proper cooling, airflow, and cable clearance
■
Easily accessible for system maintenance and
installation of system upgrades.
