POWER
CONNECTIONS
The DC power connector for the FT -100 must only be connected to a DC source providing
13.8 Volts
DC (±IO%), and capable
of
at least 22 Amperes
of
current. Always observe
proper polarity when making
DC connections:
The
RED
DC power lead connects to
the
POSITIVE
(+) DC terminal;
and
The
BLACK
DC power lead connects to
the
NEGATIVE
(-)
DC terminal.
For base station installations, Yaesu recommends the use
of
the FP-I 023, FP-I 025, or FP-
1 030A AC power supplies. Other models
of
power supplies may be used with the
FT
-100,
but the 13.8V DC input voltage,
22-Ampere
current capability, and DC cable polarity
guidelines described above must be strictly followed.
Note that other manufacturers may use the same type
of
DC
power connections as does your
FT-IOO
transceiver, but the wiring configuration
of
the other manufacturer's plug may be
different from that specified for your transceiver. Serious damage can be caused
if
improper
DC
connections are made; consult with a qualified service technician when
in
doubt.
In
mobile installations, noise pickup may
be
minimized by connecting the DC cable di-
rectly to your vehicle's battery, rather than to the ignition switch or
"accessory" circuitry.
Direct connection to the battery also provides the best voltage stability.
Tips
for
Successful Mobile Installations:
o Before connecting the
DC
cable to the battery, measure the voltage across the battery
terminals with the engine running fast enough to show a charge.
If
the voltage
is
above
15
Volts, the vehicle's voltage regulator should be adjusted to reduce the charging
voltage to
14
Volts or lower.
o Route the DC cable as far away from the ignition cables as possible.
o
If
the DC cable
is
not long enough, use #12 AWG (minimum) stranded, insulated wire
to extend it. Be certain to solder the connections at the splice securely, and provide
ample insulation for the soldered splice (heat shrink tubing plus black electrical tape
work well).
o Check the battery terminal connections frequently to be sure they are tight and not
corroded.

Caution
---------------,
Permanent damage can result
if
improper supply voltage,
or
reverse-polarity volt-
age,
is
applied to the FT-IOO. The Limited Warranty on this transceiver does not
cover damage caused by application
of
AC voltage, reversed polarity DC, or
DC
voltage outside the specified range
of
13
.8V ± I 0%. Never attempt to connect the
FT-JOO
to
a 24
Volt
battery system.

When replacing fuses, be certain to use a fuse
of
the proper rating. The FT -100
requires a 25A fast-blow fuse.
