Models CAB2-BD/-RD and CAB3-BD/-RD
Medium and Large Enclosure Doors
The Models CAB2-BD/-RD and CAB3-BD/-RD Enclosure Doors from Siemens
Industry, Inc., are used with the CAB2-BB/-RB and CAB3-BB/-RB Enclosure
Backboxes. Two doors, an outer and an inner, are required for each enclosure. The
CAB2-BD and CAB3-BD outer and inner doors are black; the CAB2-RD and CAB3-RD
outer doors are red and inner doors are black.
The outer door consists of the door frame and either two or three removable panels,
depending on the enclosure size (two for the CAB2 and three for the CAB3). Each
removable panel is secured to the door with 10-32 nuts. The removable panels may
be clear (OD-LP), blank (OD-BP/-R), or vented (OD-GP/-R) depending on the applica-
tion. The OD-BP-R and OD-GP-R panels are red. The outer door is attached to the
backbox by hinge pins and secured to the backbox by keyed latch.
The inner door has two or three openings in it for the installation of an operator
interface and other modules. There are eight threaded studs around each opening on
the inner door. These threaded studs allow equipment installation on the door. The
equipment is secured by 10-32 nuts. The inner door is permanently hinged left, is
attached to the backbox by hinge pins, and is secured to the backbox by a ¼ turn
fastener or a 10-32 x 1/2" screw (user provided), if desired.
CAB2-BD/-RD and CAB3-BD/-RD Enclosure Doors are for indoor use only in dry

the left side of the outer door. (See page 2.)
The handle for the inner door comes taped to the outside of the inner door. Remove
the tape from the handle and from the door. To insert the handle, press the handle
