Regardless of the method used, station / MDF cables are routed out of the
KSU through the opening at the lower left of the KSU housing. A cable
restraint clamp is provided and may be used to secure cables exiting the
KSU.
Typical MDF Installation
The example install below illustrates a two-cabinet installation using the MDF installation method.
66M1-50
The 66M1-50 is split into a left half and right half
for wiring terminations.
Each row is conductive between the left two
columns and the right two columns. This is the
source of the term “Split 50.”
Terminate cable pairs from the KSU and from
telephone locations on outer column pins, one lead
only per pin.
NEVER terminate two wires on one pin!
This is referred to as “double-punching” and
causes poor connection of wires on the terminal.
(
Note:
When used with “Bridging Clips,” the Split
50 block can be used to isolate trouble in wiring.)
