Installation
This chapter describes installation of the 6155 Computer.
The 6155 Computer meets the European Union Directive requirements
when installed within the European Union or EEA regions and has the
CE mark. A copy of the Declaration of Conformity is available at the
Rockwell Automation / Allen-Bradley Internet site: www.ab.com
For proper cooling, the computer requires a minimum free air space of
76mm (3 in.) behind, 51mm (2in.) above and below, and 25mm (1 in.)
on the sides of the chassis. The computer is equipped with fans to help
ensure proper cooling.
The computer can be installed in a rack cabinet that conforms to EIA
standards for equipment with 19 in. wide panels. The cabinet must be
tall enough to accommodate the computer's height and deep enough to
accommodate the unit's depth, while providing rear clearance for
cabling and air flow. A cabinet with a depth of 61 cm (24 in.) is
sufficient.
The computer is designed to be supported by rack slides or to be placed
on a shelf. The front flanges of the computer are intended to
horizontally secure the unit to the rack cabinet's front mounting rails.
ATTENTION: The 6155 Computer is intended to
operate in an industrial or control room environment,
which utilizes some form of power isolation from the
public low voltage mains. Some 6155 Computer
configurations may not comply with the EN 61000-3-2
Harmonic Emissions standard as specified by the EMC
Directive of the European Union. Obtain permission
from the local power authority before connecting any
6155 Computer configuration that draws more than 75
watts of AC power directly to the public mains.
