ITR040362042
Review the Victron Isolation Transformer 3600W 115/230V catalog ratings, AC connection points and installation notes, then add the part to your Crimp diagram.
Open this example as a new project. Use your own parts and cable lengths to make the plan yours.
Opening this part in Crimp starts a new project with the equipment placed on its own. Use the manufacturer documentation to plan its AC connections and protective devices.
The map identifies line, neutral and protective-earth connections. This page does not calculate an AC cable size or protection rating.

This is ITR040362042, the manually configured 3600 W model, not the automatic-input variant. The manufacturer manual gives 115/230 V input, 120/240 V output, and 32 A / 16 A ratings respectively. The planner’s default is the 230 V, 16 A arrangement. The transformer changes voltage configuration, not frequency.
The primary INPUT L/N/PE and secondary OUTPUT L/N/PE are distinct. Power crosses magnetically; there is no conductive primary-to-secondary line or neutral path. Afloat, shore earth remains isolated from the vessel earth. Follow the manual’s secondary neutral-to-earth link so downstream protective devices have the intended fault path. This is different from removing the earth wire from a conventional shore connection.
Installation pages 5–9 identify separate input and output jumper settings, the secondary neutral/earth link, enclosure grounding and cable glands. Check both voltage configurations against the actual shore supply and vessel distribution. Never move jumpers on an energized transformer. The special shore-to-vessel earth bridge is for the specified out-of-water maintenance/storage condition, not the normal afloat arrangement.
Soft start limits startup inrush; it does not replace feeder overcurrent protection or downstream leakage protection. Keep the IP21 enclosure dry and ventilated. The fan increases speed with temperature and thermal protection stops operation if it overheats. Verify output voltage before connecting sensitive loads, and investigate repeated thermal shutdown by checking load and cooling clearance.
Build it out
Add ITR040362042 to your diagram, then connect your batteries, chargers and loads. Crimp calculates cable sizes and checks the connections as you draw.
Every cable you draw there is sized against ABYC E-11, from the same tables as the reference on this page.
Technical reference
Check the model, ratings and connection points against your own unit before choosing installation hardware.
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.
Catalog connection points, current direction and planning limits. Check the manufacturer's pinout and connector ratings before installation.

Method & provenance
Manufacturer specifications describe the equipment. Crimp calculates cable results from the circuit and assumptions you enter.
From the maker
Manufacturer, model, ratings and which terminal does what come from the catalog. A newer revision, or the nameplate on the unit in your hand, can say something different — when it does, the nameplate wins.
ABYC E-11
Sized against ABYC E-11 — the US reference, and what Transport Canada accepts as an alternative to TP 1332 for pleasure craft under 24 m. The run length and the current above are what drive the result. Crimp doesn't know how warm your space gets; draw the cable inside an engine-bay zone on the canvas and it sizes for the heat.
Next step
