5 INSTALLATION AND OPERATION
5.1
Operation
The Model 2825R/24/XX AMCOM II rack mount diver communicator is designed to mount in
a standard electronic equipment rack, 19 inches wide. The unit has connections located on
both the front and rear of the enclosure, to facilitate system wiring. For system installation all
connections can be made to the rear of the unit, eliminating wires hanging from the front
panel.
The AMCOM II panels are graphically divided into sections; Tender Controls, Diver Controls,
and Options. Items within these areas are functions or controls relating to the Tender,
Diver(s) or Optional items.

AC Power
When the unit is connected to AC power the LED power indicator on the STATUS section of
the front panel will illuminate, confirming the presence of AC power.
The AMCOM II is designed to operate from AC voltage (90-264 V
RMS
47-440 Hz). This option
includes two 6 volt gel cell batteries (connected in series for 12 V
DC
) for backup operation in
the event of loss of AC power. The switch over to battery operation is completely automatic,
and occurs whenever AC power is interrupted. The internal rechargeable battery is
maintained at full charge while the unit is operating from AC power. AC power indicator on
the optional panel confirms the presence of AC power.
WARNING: All AC powered equipment should be used with a ground fault interrupter.
All ground fault interrupters have a built in test circuit, check for proper operation
before using.
