Ground Cable
The CommandPLUS Series Desktop Console is designed with a high degree of protection against electro-
static discharge (ESD), power line surges and telephone line surges. The protection circuitry is designed to
shunt the transient current to earth ground through the GND terminal, located on the back panel of the
console. This terminal must be connected to a high quality earth ground in order to obtain maximum
protection.

:
This ground should be connected through a utility entrance ground cable and the telephone
entrance ground cable, if different from the utility ground. Lightning is essentially RF, and as such does
not like long leads or sharp bends. Make connections appropriately.
Channel Interface Cable
A 12-pair interface cable (one supplied for each four channels of operation) plugs into the 25-pin
D-connectors on the back of the console. Refer to Figure 2 showing the rear view of the console. The
ICP9004A 4-channel console employs only one 25-pin D-connector-cable assembly for connections to the
base station(s) control and audio pairs, generally through a termination block or connector. Refer to Table
5 for wire colors and pin functions.

Some installations can use the optional CP0030A 25-pair Telco Interface Option, or the XCP0030A
25-pair Telco Interface Option Field Installation Kit, when the telephone company supplies a 50-pin
standard USOC, RJ21X Telephone Connector.
Power Supply (3308-00124-00)
The CommandPLUS Series Desktop Console uses an external power supply provided with the unit. This is
a self-contained unit that can be positioned on the desk with the console or located at some other convenient
spot. It requires an input of 90-264 V ac 50-60 Hz and delivers a regulated output of 12 V dc at 4.2 A
maximum.
Battery Revert Power Supply (XCP0080A)
The relay and associated devices for battery revert are incorporated on the main printed circuit board. This
option includes a modified power supply.
