Adding a module to a column
In a DC-powered system, power to the column can remain on during this
procedure.
If conduit or other cabling runs through the top cap, you must tag and
disconnect the cables, pull them out of the way, and reroute them after the
new module and the top cap are positioned.

Turn off power as necessary:
•
With AC power, set the main circuit breaker for the column to OFF
(down) in the rear of the pedestal.
DANGER OF ELECTRIC SHOCK
Due to hazardous voltage in AC-powered systems,
power to the entire column must be shut down. This
shuts down all functions in the column.
•
With DC power, set the switch on the module power supply and the
circuit breaker in the rear of the pedestal to OFF (down) for the
module being added.
