RTX 2000 12V / 9620001310
Review how the Dometic CoolAir RTX 2000 12V 9620001310 connects, how it operates and which installation requirements apply to this model.
Open this example as a new project. Use your own parts and cable lengths to make the plan yours.
The 12 V RTX uses separately protected main-power and voltage-monitor connections. Its cooling capacity is not its electrical input. Follow the model-specific four-wire installation and its 80 A main and 2 A monitoring protection.

This is the 12 V unit, SKU 9620001310, as identified on Dometic's product page. The currently linked installation table, page 15, specifies 10–60 A and a 9–15 V operating range for RTX 2000 12 V. Older family instructions list 58 A; the catalog follows the newer 60 A limit. Cooling capacity is not electrical input power, and the SKU page and family table use different cooling-capacity figures, so no cooling wattage is inserted into the electrical budget.
The wiring diagram and instructions, pages 5 and 11, separate the heavy power circuit from battery-voltage monitoring. The main red positive lead needs 80 A protection; its black return carries the operating current. The separate red monitoring lead needs 2 A protection, with its own black reference return. Both pairs must follow Dometic's diagram.
The catalog's `pos` and `neg` terminals are the power pair. `sense-pos` and `sense-neg` represent the monitoring pair and do not carry the compressor's 60 A. Their 2 A boundary identifies protection, not sensing consumption. A two-wire example omits part of the actual installation; do not join the monitoring lead into the heavy feed merely to simplify the drawing.
Use the mounting kit approved for the vehicle and confirm the roof opening, support, roof thickness and permitted mounting angle. The SKU installation prerequisites explain the roof and mounting checks. Keep service access and air paths clear and follow the seal and fastener sequence. Do not remove an emergency exit to install the unit.
The installer configuration, pages 12–13, includes the battery monitor; the 12 V factory undervoltage setting is 11.5 V. That setting protects operation, and does not replace a battery-specific discharge plan. The 60 A catalog value is an upper electrical load, so an hours-per-day budget at that value is conservative rather than a measured average. If the unit stops on low voltage, compare voltage at the battery and at the power terminals under load, then check the separate monitor wiring, fuses and connections.
Build it out
Add RTX 2000 12V / 9620001310 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.
