The module is shipped in Class B position, remove shunt for Class
A. When operating in Class A, alternate modules are paired together
(+0/+1, +2/+3, +4/+5, +6/+7, +8/+9), resulting in a total of five
modules. For example, if the base address switch is set to 28, then 30,
32, 34 and 36 will be automatically assigned to the modules while 29, 31,
33, 35 and 37 are available to be used for other modules on the SLC. For
Class A and B operation, DO NOT set the lowest address above 90, as the
other modules will be assigned to nonexistent addresses.
4. A shunt is provided to disable a maximum of two unused modules in
Class B operation and one unused module in Class A operation. Modules
are disabled from the highest address and work downward. If two mod-
ules are disabled, the lowest eight addresses will be functional, while the

highest two will be disabled. For example, in Class B operation, if the
shunt for Address Disable is placed on "two" and the base switch is set
to 28, the modules will be assigned to 28, 29, 30, 31, 32, 33, 34 and 35
while disabling the highest two positions.
NOTE: Place unused shunts on single pin to store on board for future use.
NOTE: Power must not be applied to the unit when changing functionality
of the shunts.
WIRING NOTES
• Power-limited circuits must employ type FPL, FPLR, or FPLP cable as
required by Article 760 of the NEC.
