Installing the Modular Adaptor
The Modular Adaptor (P/N 62598) simplifies the
installation of stations in a BUSINESSCOM PLUS 
only.Two connectors are recommended for each system.
This section provides information on installing a
Modular Adaptor.
Refer to Figure 2-34 Modular  Adaptor  Installation:
1. The 
 on the back of the adaptor is
connected to either 
 or B2 on the side of the
KSU. The screws on the adaptor are screwed into
predrilled holes in the KSU.
2. Mount the wall-mounting brackets on 
 so as
to offset the KSU from the wall.
3. The numbers on the block correspond to the column
markedModular Adaptor Number on the 
block illustrations for the system (see Table 2-1,
BUSINESSCOM PLUS 
 Cut Down Block, and Table
2-2, BUSINESSCOM PLUS 12 Cut Down Block).

Installing  and DISA Ports
This section provides information on installing the
 PCB in a BUSINESSCOM PLUS  or the B-STU-D
PCB in a BUSINESSCOM PLUS 
 Both  are used
for Off-Premises Extensions and DISA ports.
External Ring
GeneratorUse of the 
 or B-STU-D  for  requires
an External Ring Generator power source in order to
provide non-interrupted ring generator output in the
range of 90 VAC at a nominal frequency of 20 Hz.
External
Talk BatteryThe 
 or B-STU-D  for On-Premise Single-Line
sets or DISA ports may use the internal talk battery
source from the system power supply.
An external Talk Battery supply must be used with
these 
 for Off-Premise Extensions  The
Talk Battery supply must correspond with the Telco
OPX requirements and be either 24 VDC or 48 VDC out-
put.Neither Talk Battery output may be lead-grounded.
Ground Connection
for 
When the  or B-STU-D  are used for 
or served by an External Talk Battery source, they
must be grounded to the CWP ground.
The GND connection to the OPX card, located on
the station B Block,provides the OPX Reference
Ground for Telco OPX circuits.
The ETH connection to the OPX card, located on
the station B Block,provides Protective Ground
to the OPX card 
 protection) from power surges.
The GND and ETH leads should be connected to the same
CWP ground source.

 B2 Block
Connections):
1. Connect the pair of wires from the station to the
D clips of the AT/AR pair on the B Block corres-
ponding to the station number being installed.
2. Install bridging clips.
Each 
 PCB must be connected to a ring
generator source.
Connect the TIE Ring Generator
(P/N 12185) to the MDF as follows (see Figure 2-36
and Table 2-4):
1. Connect the output terminals from the Ring
Generator to the B2 Block, D clips 
 (the
RED-BRN, BRN-RED pair).
2. Install bridging clips.
3. Connect the input terminals designated + from the
RG to the B2 Block, D clip 19, the RED-SLT wire.
4. Connect the input terminal des-ignated G from the RG
to the B2 Block, D clip 20, the SLT-RED wire.
 Install bridging clips.
(To connect the B-STU-D PCB to a ring generator
source, seeRing Generator Connection in Installing
the B-STU-D 
Earth Ground
Connection Whenever a 
 PCB is installed in a BUSINESSCOM
PLUS 
 using a  facility, an earth ground is
required.
To connect the earth ground (see Figure 2-36 and
Table 
1. Connect a wire from the B2 Block, D clips 
(BLK-BLU, BLU-BLK pair) to an earth ground.
2. Install bridging clips.
External Battery
Connection T o  connect an external battery (see Table 
1. Connect a wire from clip 23 on the B2 Block to the
external battery positive terminal.
2. Connect a wire from clip 24 on the B2 Block to the
negative terminal.
MAKE SURE THAT NEITHER BATTERY TERMINAL
IS GROUNDED.
