Accessibility
Allowing space around the rack (Rear access racks)
o
Rear access racks require adequate space in front to remove and replace
modules (minimum 80cm, 150cm recommended) and rear access to allow the
rear door for ventilation purposes and so that the door can be opened fully for
installation and maintenance access (minimum 100cm, 180cm recommended).
o
Racks may be positioned with their side to a wall surface, and may be located
side to side as required.
o
Where top access is planned for cables, ensure space above the rack is
adequate to allow for the bend radius of the supply cable, or access for main
power supply cable or bus bar trunking and load cable trunking. Allow adequate
space to allow for future cable checking and maintenance access to trunking lids.
Allowing space around the rack (Swing frame racks)
o
Swing frame racks require adequate space in front to remove and replace
modules and sufficient space for the door to be hinged fully open for access to
wiring terminations inside the rack. A distance of 1.8m is recommended between
the front of the rack and the wall.
o
Racks may be positioned with their side and rear to a wall surface, and may be
located side to side as required.
o
Where top access is planned for cables, ensure space above the rack is
adequate to allow for the bend radius of the supply cable, or access for main
power supply cable or bus bar trunking and load cable trunking. Allow adequate
space to allow for future cable checking and maintenance access to trunking lids.
