Circuit Pack
Installation
When replacing a circuit pack or adding a new circuit pack to a
controller which is in service, the circuit pack hardware must
first be set up as described in “Basic Hardware Setup”
in this
section.
WARNING Circuit packs can be damaged by static electricity.
Operators should always be grounded when handling circuit
packs. Connect the grounding wriststrap to the ESD ground
plug on the controller front panel.
To install a circuit pack, simply open the controller front panel,
pull out the drawer, and slide the board along its guide rails into
the proper backplane connectors. Backplane connectors are
arranged so that circuit packs cannot be inserted in the wrong
slots. It is not necessary to pull fuses or power down the plant or
controller in any manner to remove or add any circuit packs in
the controller.
