Step 2:
Carefully swing the bottom edge of the board towards the back of
the board until it touches the short standoff attached to the chassis.
Step 3:
Align the long standoff with the short standoff and tighten.

Step 1:
Insert the bottom edge of the CRF-300-6 module down into a front
slot of the chassis.
Step 2: Carefully swing the upper edge of the board towards the back of
the chassis until it touches the 11/4″ (31.75mm) standoffs installed
on the rear module.
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.
WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and
regulations.
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
2. Make electrical connections by stripping approximately 1/4˝ (6.35mm)
of insulation from the end of the wire sliding the bare end of the wire
under the clamping plate, and tightening 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). The
remaining 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. 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 up
-
per rotary switch. If the panel does not support extended addressing, do not
set the lowest address above 94.
4. A shunt is provided to disable a maximum of three unused modules.
Modules are disabled from the highest address and work downward. If
two modules are disabled, the lowest four addresses will be functional,
while the highest two will be disabled. For example, if the shunt for Ad
-
dress Disable is placed on “two” and the base address switch is set to 28,
the modules will be assigned to 28, 29, 30 and 31.
NOTE: Power must not be applied to the unit when changing functionality of
the shunts.

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 CRF-300-6 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 a
module.
