J7 connectors
The output voltage of the connector J7 is 120 Vac and
the maximum current is 1A. Do not connect this plug to
a device with a leakage current greater than 1.75 mA.
(pin 11 positive, pin
(pin 12 positive, pin
exception of an overtemp
CAUTION!
The 120 Vac, 1 A maximum (independent of line
Voltage) output Voltage is present when the main
power switch is set to 1 position and after START push-
button is pressed and will remain present until a fault

condition is displayed on the front panel display or the
turbopump is stopped.
The connector J7 is for vent device, forepump
connector coils, pump cooling fan etc.
To make connections, remove the plug and wire the
pins (maximum wire size 18 AWG, 1 mm²) as indicated
4
in the figure to obtain the desired capability.
Forepump relay coil is an independent user supplied
item.
Connection J10
Controller-to-Pump Connection
A five-meter long cable is provided to connect the
controller to the pump. The following figures show the
controller output connector configuration where pins:
•
A-F = upper bearing sensor
•
B-C-D = 54 Vac 3-phase output to pump motor
stator
•
E = ground
•
A-G =lower bearing sensor
