Figure 4: Mounting the CHS-6 chassis
The BB-XP 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 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 neces-
sary screws and standoffs are supplied with the modules.

Figure 5: Installation of rear module only, method one
Step 1: Insert the bottom of the XP6-C 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 instruc-
tions 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 XP module.

Figure 6a:
Installation of XP6-C module in a rear
chassis position, method two
Step 1: Insert the bottom edge of the XP6-C module down into a
rear slot of the chassis.
Step 2: Carefully swing the upper edge of the board towards the
back of the chassis until it touches the short standoff
attached to the chassis.
Step 3: Align the long standoff with the short standoff and tighten.

WIRING
NOTE:
All wiring must conform to applicable local codes, ordi-
nances, and regulations.
1. Install module wiring in accordance with the job drawings and
appropriate wiring diagrams.
2. All wiring to the XP6-C is done via terminal blocks. In order
to properly make electrical connections strip approximately
1
/
4
″
of insulation from the end of wire, sliding the bare end of the
wire under the clamping plate screw.
3. Set the address on the modules per the job drawing. Use the
rotary code switches to set the address of the first module
(between 01 and 154).
To select Class B operation, install the J1 Shunt. The remain-
ing modules are automatically assigned to the next five higher
addresses. For example, if the base address switch is set to 28, the
next five modules will be addressed to 29, 30, 31, 32, and 33.
To select Class A operation, remove the J1 Shunt. A maximum
of three Class A circuits are available. For example, if the base
address switch is set to 28, 30 and 32 will be automatically
assigned to the modules while 29, 31 and 33 are available to be
used for other modules on the SLC. For Class A and B operation,
DO NOT set the lowest address above 154, as the other modules
will be assigned to nonexistent addresses.
NOTE:
Some panels support extended addressing. In order to
set the module above address 99 on compatible systems,
carefully remove the stop on the upper rotary switch
(see Figure 7). If the panel does not support extended
addressing, do not set the lowest address above 94.
