The generator's data plate gives the voltage, current and frequency rating
of
the generator. An AC wiring
decal
is
affixed
to
the inside
of
the louvered cover on the generator end. A diagram of the various AC volt-
age connections is provided on the decal.
The generator
is
a single-phase, reconnectable 120 Volts AC two-wire
or
120/240 Volts AC three-wire, at 60
Hertz;
or
110 Volts AC two-wire, 110/220 Volts AC three-wire,
or
220 Volts AC two-wire, at 50 Hertz. Refer
to the
"SYSTEM SPECIFICATIONS" section of this manual for generator ratings, page
13
for
the BCG 4.0KW,
and page 17
for
the BCG 6.5KW.
NOTE: The frame ground wire must be moved when changing from 110 Volts,
50
Hertz
to
/220
Volts, 50 Hertz.
A circuit breaker should be installed between the generator and the AC load. This circuit breaker should be
rated at 120%
of
the generator's AC output and be able
to
react quickly to overloads, subject
to
motor
start-
ing considerations.

For making connections
to
the AC terminal block, use terminal ends for
#10
studs which will accept multi-
strand wire sized
for
the number
of
conductors in the bundle, the rating of the conductor's insulation, and
amperage that will be drawn through the conductor(s). (Refer
to
the generator's data plate for the gener-
ator's amperage and voltage ratings.)
NOTE: When changing Hertz produced
by
the generator, an engine speed adjustment at the
governor must be made. The AC output connections on the above illustrated terminal blocks
must be selected for the voltage and Hertz
to
be produced. A plug at the capacitor must be
changed
for
50 (#5)
or
60 (#6) Hertz use. Early models with 3 wire connections
to
the in-
tegral controller require a 50 (#5) or
60
(#6) Hertz connection change at the bridge rectifier
in the DC charging circuit. Refer
to
the "Generator's Internal Wiring Schematic" on page
57.
