Step 1: Insert the bottom edge of the CR-6 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.

Step 1: Insert the bottom edge of the CR-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 1 1 /
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: Power must not be applied to the unit when changing functionality of
the shunts.
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 firstmodule (between 01 and 94). 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 94, as the other modules will be assigned to
nonexistent addresses.
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.
