Installation & Operation Manual for the 

Active Vibration Cancellation (AVC) System 

Attach the Wiring Harnesses 

The components of the AVC system are interconnected with the cryocooler and with other interfacing equipment 
using the two supplied wiring harnesses: the power wiring harness, and the instrumentation wiring harness. 

Power Wiring Harness 

The power wiring harness (figure 6) has four connections: 

• 

DC Power Supply Leads

 – A black lead and a red lead that connect to the DC power supply [not included] 

for the cooler. 

• 

AVC Controller Power Wiring Harness Connector

 – A D-sub connector with various pin sizes that connects 

to the power wiring harness connector on the AVC controller. 

• 

Cryocooler Power Connector

 – A two-pin connector that mounts to the back plate of the cryocooler and 

connects to the two feedthrough pins used to power the cryocooler. 

• 

AVC Balancer Power Connector

 – A small, two-conductor white plastic connector that connects to the pow-

er connector on the AVC balancer’s power cable (figure 2).
