The front MMF-300-10 module positions of each chassis are offset below the
rear MMF-300-10 module positions so that all of the status indicators are vis-
ible.
Cabinets
A BB-6 cabinet will house the CH-6 chassis with up to six MMF-300-10 mod-
ules installed on it. Refer to cabinet installation documents for dimensions.
The BB-2 cabinet houses one or two MMF-300-10 modules on the internal
chassis that is part of the cabinet. Refer to cabinet installation documents for
dimensions.
INSTALLATION STEPS
1. Cabinet Mounting
In a clean, dry area, mount the backbox using the four holes provided in
the back surface of the cabinet (Figure 3).
2. Chassis Installation
The CH-6 chassis is mounted in the BB-6. 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).

3. Module Installation
There are two methods for installing a module in the rear position of a
chassis. 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 MMF-300-10 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 posi-
tion installation is possible only if the rear position is filled with a module.
