Before Installing An Expansion Ksu; Connecting The Ksu-B And Ksu-E Cabinets Together - NEC UX5000 Hardware Manual

Chapter 1 - Installing the KSUs
The Expansion KSU uses an expansion bracket which attaches to the right side of the Controlling/Base KSU.
When multiple cabinets (combined KSU-B and KSU-E or a KSU-A) are to be connected, an Expansion KSU
kit is required to connect the KSUs together (using the EXIFU PCB).
●
Note: When wall-mounting a UX5000 system, make sure the wall can support the weight of the
KSUs. It is recommended that plywood first be installed on the wall where the KSUs will be positioned,
allowing for secure anchoring.
