We just received a used Matsuura H.Plus 405, without a full wiring diagram.

There is a problem that is keeping us from being able to use the machine that we are told is due to a loose connection on a terminal block XT-36, located in the APC Box (according to the manuals we have)

Our problem is we can't find XT-36.
We found just about every terminal strip but XT-36


Does anyone have this machine and knows where this strip can be found?


Our only other option than to find it ourselves is to fly in a service person to show us where is it... (read big $$$$$)
