GENERATOR AC VOLTAGE CONNECTIONS
DESCRIPTION
. The regulator is equipped with seven numbered terminals (0
to 6) and their related brass jumpers. The illustrations show
connection points and jumpers for the 3 phase configuration
of
the generator. The sensing leads connect between pin #1
and pin #2 on the AC terminal block and connection #2 and
#0 on the voltage regulator board.
BLK AVR
NOTE: Series Delta requires the installation of a jumper on
the regulator board between terminal B and 10.
