3. Wiring Example
when EX-630 is used
1. For LM units: Connect K1 through K16 of the exchange to L1
through L16 of the terminal board (A), and L1
through L16 of the exchange to L1 through L16
of the terminal board (B).
Use YR-810 cable for this connection.
2. For PI units: Connect PI1 (J9, zone 1-7 plus All-call) and PI2
(J10, zone 8-15) of the exchange to P1 and P2 of
the terminal board (A), respectively.
Similarly, connect PIS (J11, zone 16-23) and PI4
(J12, zone 24-31) to P1 and P2 of the terminal
board (B), respectively.
UseYR-801 cable for this connection.
3. For TI units: Connect TI1 (J11, in the place of PI3) and TI2
(J12, in the place of PI4) of the exchange to each
T1 of the terminal boards (A) and (B), respec-
tively, with YR-801 cable.
4. For SI unit: Connect K2 or an exchange to L2 of a terminal
board (A).
