132 Specifications and requirements
• 2U 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 135 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 15.2 cm (6 inches) 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 38.1 cm (15 inches) 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.
• 4004 Series controller and drive enclosures are suitable for connection to intra-building or non-exposed
wiring or cabling only.
• 4004 Series controller and drive enclosures are suitable for installation in Network Telecommunication
Facilities and locations where the NEC applies. 4004 Series enclosures are not suitable for Outside
Plant (OSP) installations.
Management host requirements
A local management host with at least one mini-USB connection is recommended for the initial installation
and configuration of a controller enclosure. After you configure one or both of the controller modules with
an IP address, you then use a remote management host on an Ethernet network to manage and monitor.
NOTE: Connections to this device must be made with shielded cables – grounded at both ends – with
metallic RFI/EMI connector hoods, in order to maintain compliance with NEBS and FCC Rules and
Regulations.
