66M1-50
•
The 66M1-50 is split into a left and right half for
termination wiring.
•
Each row conducts between the two left
columns and the two right columns. This is the
source of the term “Split 50”
•
Be sure to treminate cable pairs from the KSU
and from telephone locations on outer column
pins (one lead only per pin).
IMPORTANT!
NEVER
terminate two wires on one pin!
This is refered 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.
