doors than the smaller 8U and 15U cabinets.
The 28U and 40U cabinets are available as factory build-to-order systems. Use the 4100Cost tool to determine
the cabinet size and panel contents.

Mounting the cabinet

Ensure the following when mounting a 28U or 40U cabinet:
⋅
The operator can access the cabinet.
⋅
Ensure that all fan controls and the Fire Brigade Interface are between 750 millimeters and 1850
millimeters above the floor.
⋅
There is sufficient space to fully open the cabinet door, particularly for cabinets used by emergency
personnel.
⋅
There is access to the cable entry points for field wiring.
Fire panel height requirement and minimum access requirements are outlined in AS 1670.1. The
recommended cabinet wall fixing is M8 screws or studs.
28U cabinets are wall mounted. There are six dimpled mounting holes in the rear of the cabinet. The mounting
holes are accessible from inside the cabinet when the APS and CPU bays are removed.
40U cabinets are floor mounted, and secured to the wall using the dimpled mounting holes in the rear of the
cabinet. The mounting holes are accessible from inside the cabinet when the APS and CPU bays, and lowest
Expansion bay are removed.
The standard door opening is to the left, but the cabinets can be ordered or adjusted on site to open to the right.
Note:
40U cabinets may require a plinth to ensure that all controls and indicators are positioned
adhering to height restrictions.
