Electrical Guidelines

These enclosures work with single-phase power systems having an earth ground
■
connection. To reduce the risk of electric shock, do not plug an enclosure into
any other type of power system. Contact your facilities manager or a qualified
electrician if you are not sure what type of power is supplied to your building.
Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce
■
the risk of electric shock, always plug the cord into a grounded power outlet.
Do not use household extension cords with the enclosures. Not all power cords
■
have the same current ratings. Household extension cords do not have overload
protection and are not meant for use with computer systems.

Ventilation Requirements

Refer to "Environmental Requirements" on page 75 for detailed environmental
requirements.
Do not block or cover ventilation openings at the front and rear of an enclosure.
■
Never place an enclosure near a radiator or heating vent. Failure to follow these
guidelines can cause overheating and affect the reliability and warranty of your
enclosure.
Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to
■
ensure adequate airflow for cooling. No cooling clearance is required on the
sides, top, or bottom of enclosures.
Leave enough space in front and in back of an enclosure to allow access to
■
enclosure components for servicing. Removing a component requires a clearance
of at least 15 inches (37 cm) in front of and behind the enclosure.

Cabling Requirements

Keep power and interface cables clear of foot traffic. Route cables in locations
■
that protect the cables from damage.
Route interface cables away from motors and other sources of magnetic or radio
■
frequency interference.
Stay within the cable length limitations.
