4.6.3 J6 EXTERNAL OSCILLATOR
This is an External Oscillator Input. This connector is a DA15S type. If the
Frequency Select Switch is rotated to the EXT position and the cabinet is ON,
inputs applied to J6 are amplified 25 times at the output terminals.
Example:
4.80 VAC, 60 Hz input at J6 equals
120 VAC, 60 Hz at the output contactor.
Pin Numbers are as follows:
7
Ext Phase A Oscillator Input
15
Ext Phase B Oscillator Input
8
Ext Phase C Oscillator Input

4.6.4 J5 AND J7 SYSTEM METERING OUTPUTS
J5 is a System Volts output signal connector. System Volts are divided down by
25 to 1 and sent to this connector. This connector is a DA15S type.
Example:
120 VAC, 60 Hz at the output contactor equals
4.80 VAC, 60 Hz at J5.
Pin Numbers are as follows:
1
Phase A System Volts Output
11
Phase B System Volts Output
8
Phase C System Volts Output

J7 is a System Amps output signal connector. System Amps are divided down
by 400 to 1 and sent to this connector. This connector is a DA15S type.
Example:
400 AAC, 60 Hz total system output equals
1.00 VAC, 60 Hz at J7.
Pin Numbers are as follows:
2
Phase A System Amps Output
7
Phase B System Amps Output
11
Phase C System Amps Output
