6-3 Connection of station plug to jack
6-4 Mounting option unit
(1) Bl unit
Insert the Bl unit into its exclusive bay and connect its connector to CN4 on the CC unit.
Notes
(1) Use 4"×2" back box for YC-603.
(2) Terminals 1 and 2 inside the jack
have no polarity.
(2) Mounting other option units than the Bl unit
Option units other than the BI-20 are all connected to the CC unit via a common bus and so, any bay can be
used to mount them so far as it is not the one solely intended for the Bl unit. The EX-200 exchange has 5 bays
for option units, while the FC-210 has 6 bays. Insert the option units in order, stating with the bay closest to
the CC unit, and connect the connector as illustrated below.
Notes
(1) No YR-821 cable is needed when a maximum of 5 option units is mounted.
(2) Connect an earth wire of the YR-821 to the earth terminal of the FC-210.
