FIPLEX BIDIRECTIONAL AMPLIFIER - USER MANUAL
AC Power
THE POWER SUPPLY UNIT CONTAINS DANGEROUS VOLTAGE THAT CAN
CAUSE ELECTRIC SHOCK.
DISCONNECT THE MAINS PRIOR TO ANY WORK IN THE REPEATER.
AUTHORIZED SERVICE PERSONNEL ONLY ARE ALLOWED TO SERVICE
REPEATERS WHILE THE MAINS IS CONNECTED.
Mains should be 110-220 VAC 50-60 Hz with ground terminal connection (yellow
and green cable).
A good ground connection must be done in order to preserve the equipment and
system reliability.
A 2 Amps fuse (5 x 20mm) is used as power supply protection against severe
failure in mains power.
DANGER
ALWAYS REMOVE MAINS POWER BEFORE CHECKING OR CHANGING FUSES.
120 VAC CAN BE LETHAL.
DC Power
There is an alternative way to power the repeater, this is by means of a DC power
source. DC power must be feed to the repeater main board by means of a specific
connector (please see figure below). Accessing the repeater from the outside with the DC
power cord must be done through the cable gland labeled “BATERY BACKUP”.
Nominal DC voltage is specified in the repeater datasheet specifications.
When DC voltage goes under the 80% of the nominal voltage, system will be in
BATTERY FAIL status.
