Question about Installation of Morningstar Inverter

I wired my Morningstar inverter directly to a 30A RV receptacle (I turn off the converter before plugging in), and plug the TT power cord into it. IIRC, I just grounded the ground lead in the receptacle to the frame.

It depends on how you'll be installing your inverter. Mine is wired "whole house" so it's using the breaker panels ground which is likely the RV's frame/chassis.

thanks

reviving an old thread. I'm installing the Morningstar 300 as well. I understand about connecting the Earthground to the frame/chassis.

My question is where to connect the AC ground wire that goes to the 120V receptacle? The frame as well? The installation instructions don't mention it at all.

Have you got the TS-RM-2 remote display?
If so you can turn it on/off from that
Might not be a need for the remote on/off switch

Thanks for all your responses.
No, don't have the Morningstar remote -- just going to put a simple on-off throw single pole switch. I have a Trimetric that I can get all kinds of data off of.

Suggest you keep the connections completely isolated from all others
It is either 12 Volt or something less - not sure if it's some special drive signal or simply a connection to ground
(Will go measure if need be)
In a few installations, I have used DPDT toggle switches to both turn the unit on/off and switch power to an external LED

One more question comes to mind. There are contacts on the inverter to connect a remote switch, which I will be doing. Below I copied and pasted the directions. I wonder if the feed off that is 12V? Judging from the max 16 AWG wire, I'm thinking it might be. I have a 12V toggle switch with an LED on-light built in. I would like to use that switch, but the instructions don't state if the feed is 12V. Does anyone know?


From the instructions:

A remote switch can be installed to switch the SureSine AC output on/off from a remote location allowing the SureSine to be installed in an inaccessible location or enclosure. A single-pole, single-throw switch (SPST) is required (not included).
1.
Using a small gauge wire (max. 1.0 mm2 or 16 AWG, 300V min.), wire one terminal of the Remote On/Off terminal block to one end of a SPST switch.
2.
From the other contact on the switch, wire another small gauge wire to the remaining open terminal on the Remote On/Off terminal block.

A short length of marine 12/2 duplex like from genuiinedealz.com sounds much more inviting.

Thanks, everyone. How about using 12 gauge THNN stranded? None of this short wire is exposed to the elements, so romex nor conduit isn't necessary.
