KSU ASSEMBLY – ADD-ON MODULES
• Whenever you expand the DX-120 system, you install a module into one of the KSU cabinets.
• Modules are connected to the various connectors on the 408M/E.
• Modules are mounted using standoff posts.
- Two standoff post sizes are used in the DX-120.
- The APM4 modules must be installed using the 2.5 cm (nickel) standoffs.
- All other modules use the 1.5 cm (brass) standoffs.
IMPORTANT!
Proper use of standoff is imperative to assure proper system operation.
