Dear All,
you can find in attachment the LV cable diagram. To ensure the voltage 
sense function will work properly and be able to test the interlocks 
with the cable disconnected, you should:
- short pin 1 and 2
- short pin 4 and 5
on connectors J2 and J3 (white 6 pin connectors).
Note that the pin numbering shown for J2 and J3 in the diagram is what 
you would see looking at the connector from the wires side.
Let us know if you have any question.
Regards,
     Raffaella
