Return to Task List
When installing additional features or equipment, it may be necessary to install additional port circuit
packs. See Circuit Packs and Circuit Modules by Code for a list of circuit packs. This is a general
procedure to use when adding features or equipment that require adding circuit packs.
CAUTION:
Control circuit packs with white rectangles on the label cannot be removed or installed
when the power is on. The port circuit packs with gray rectangles on the label (older
version port circuit packs had purple labels) can be removed or installed when the power
is on.
