Have been emailing iOptron support regarding the above issue and today have sent off the iPolar camera and the input board opposite for their examination.
They sent me the following link to instructions on how to remove the iPolar, input board and cables for shipping.

I only sent the camera and input board as the cables connect up into the hub instead of going directly through. I was uneasy about removing the saddle to get to the hub connection points but they said that unless I could see any evidence of pinching or poor cable health not to worry. I felt the less I disturbed them the better.
Their response to emails over the last few days has been very quick and helpful in manner.
