WARNING
A fully loaded module weighs approximately 60 kg
(130 lbs). More than one person is required to move
a module.
DANGER OF ELECTRIC SHOCK
In a DC-powered system, power to the column can
remain on during the following procedures. In an
AC-powered system, however, power to the entire
column must be shut down throughout the
procedures.
If conduit or other cabling runs through modules that are being moved, you
must tag and disconnect the cables, pull them out of the modules, and reroute
them after all of the modules are repositioned. The top cap can remain on the
module to which it is attached.
