Installing the Modules 2
CAUTION:
When installing the modules, use a properly grounded wrist strap to
prevent damage from electrostatic discharge (ESD), and avoid touching
leads, connectors, pins, and other components. The wrist strap can be
clipped to the ground-screw or plugged into the hole next to the ground-
screw.
WARNING:
All unused slots must be covered with a blank panel. Remove back panels
only from slots where modules will be installed.
Guidelines 2
Follow these guidelines when you install modules, as indicated on the Control
Unit Diagram of Form 1, System Planning:
■ For a MERLIN MAGIX Release 1.0 system, do not leave empty slots
between modules. The system ignores modules installed beyond any
empty slot.
■ For a MERLIN MAGIX Release 1.5 system, you may leave empty slots
between modules, but you must program these empty slots to be Bridge
modules. (See “Upgrading to the MERLIN MAGIX System” on page 7-9.)
■ If a phantom module (a programmed empty slot) is indicated on the Control
Unit Diagram, make sure the slot remains empty and do not install any
modules to the right of it. The system ignores any modules installed to the
right of a programmed empty slot.
■ Remove a blank panel from a slot by prying up the latch at the bottom of
the panel with a flat bladed screwdriver.
■ Make sure you install each module in its assigned slot. If you install a
module in the wrong slot, the system will not function properly.
