We dealt with Advance Yacht Systems throughout this project who provided an invaluable source of information and advice including suitable locations for mounting the XTM power management unit bearing in mind it needs to remain within 3 metres of the battery and having the two cabin version of the Oceanis 43 means that there is good access to space above and behind the prop shaft in the rear cabin.
The large cable ties were undone and we constructed a full width plinth which was supported on the starboard side by an off cut of the plinth and rested on the support brace on the port side. Both were bonded and screwed. An additional central brace was also added to provide additional support. This was bonded to the hull and screwed to the plinth.
The XTM was placed on a smaller piece of wood that extended beyond the connections to allow some cable management when we have finished, however all of the inverter was supported by the plinth. The XTM comes with three point fixing however I chose to drill another two fixing points for a five point fix.
