SYSTEM INTERCONNECTION
The B & K Exciter Body Type 4801 is supplied with the following cables
for interconnection to the 2707:
a) a 5 conductor 30/0.25 mm 250 V cable for interconnection between
the AMPLIFIER OUTPUT and the Exciter Head moving coil. Dia-
gonal conductors in this cable should be connected together, one pair
going to pin 1 and the other to pin 2 of the connectors. The fifth
conductor is used for the Exciter Interlock signal and is connected to
pin 3.
b) a 4 conductor (use diagonal conductors paired) 32/0.20 mm 750 V
cable for the AC POWER EXCITER connection.
c) a 2 conductor 24/0.20 mm 250 V cable for the EXCITER TRIGGER
connection.
The system is connected as shown in Fig.3.3 and details are given in the
