NOTE:
If the Battery or is removed when power is off the contents of SRAM (on the CPU
Module) will not be retained. Once a Battery has been removed, don’t install a
replacement Battery for at least one minute unless SW2-5 on the CPU has been
set OFF.
2.3.11 Installation of a Bezel Assembly (see Figure 2-2 & 2-37)
Bezel Assemblies provide a protective cover and wire routing for any two ControlWave
EFM I/O Modules. One Bezel Assembly will cover Slots 3 & 4 (when equipped with I/O
Modules) and will provide the following functions:
• It can be removed to access the two I/O Modules.
• Bundled wires and cables are routed downward between the Modules and the Bezel.
• The Bezel is functional and its appearance is contiguous with the I/O Modules.
Bezel Assemblies are provided when two I/O Modules are ordered and should be installed
whenever the unit is operational (except during service). The Bezel is secured to the Covers
of two I/O Modules via four built-in latches (hooks). To remove the Bezel assembly, gently
grasp its sides and pull up and then away from the Chassis.
Installation of the Bezel Assembly requires that its latches be aligned with their mating
notches on the associated left and right I/O Module Covers. Once the Bezel has been
properly aligned with the notches on the I/O Module Covers, simply press in and then
downward to set it into place.
