Power Supply (3308-00124-00)
The ICP9000 Navigator MCU requires an external power supply provided with the unit. This is a self-
contained unit that can be located at some convenient spot near the MCU. It requires an input of 90–264
V ac 50-60 Hz and delivers a regulated output of 12 V dc at 4.2 amps 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.
Ground Cable
The ICP9000 Navigator MCU 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.
N
OTE
: 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.
External Accessories Connector
The rear panel connector labeled EXTERNAL ACCESSORIES , an 8-pin modular connector, provides for
a desk microphone connection. It can also be used as a convenient connection to the Audio Accessory
Box if only a short cable length is required. The pinout is mirrored with respect to J1 on the Audio
Accessory Box so the modular cable provided with the Audio Accessory Box will provide the proper
connection. See the pinout in Table 5 below.
