The front CR-6 module positions of each chassis are offset below the rear CR-6
module positions so that all of the status indicators are visible.
Cabinets
A BB-6 cabinet will house the CH-6 chassis with up to six CR-6 modules in-
stalled on it.
The BB-2 cabinet houses one or two CR-6 modules on the internal chassis that
is part of the cabinet. Refer to cabinet installation documents for dimensions.
INSTALLATION STEPS
1. Cabinet Mounting
FIGURE 3: TYPICAL MOUNTING HOLE LOCATIONS

In a clean, dry area, mount the backbox using the four holes provided in the
back surface of the cabinet.
2. Chassis Installation
The CH-6 chassis is mounted in the BB-6 cabinet. It is shipped with two self-
threading screws, which are used to fasten the chassis to the back wall of the
cabinet (see Figure 4).

TO BACK OF CABINET
The BB-2 cabinet comes with the chassis already installed, so no mounting
is necessary.
3. Module Installation
There are two methods for installing a module in the rear position of a chas-
sis. Method one is for installation of a rear module only, when no module will
be installed in front of it. Refer to Figure 5 for instructions. Method two is for
installation of a rear module when another module will be installed in the
chassis position in front of it. Refer to Figures 6a and 6b for method two. All
necessary screws and standoffs are supplied with the modules.

Step 1:
Insert the bottom of the CR-6 module down into a rear slot
on the chassis.
Step 2: Carefully swing the upper edge of the board back towards the back of
the chassis until it touches the two standoffs.
Step 3: Align two 4-40 screws with the two standoffs and tighten.
Step 4:
Address and wire the modules according to the instructions in
this manual.
The steps in Figures 6a and 6b describe and illustrate module installation
when the rear chassis position and the position in front of it will be filled.
Front position installation is possible only if the rear position is filled with an
input/output module.
