Older SonnenBraun Tanning Bed - Need help wiring

Acquired older SonnenBraun tanning bed from a tanning salon.
The only identification I can locate is tag that says SonnenBraun, Redmond WA with UL symbol and 7J84, with a counter next to it: GRASSLIN, (hour counter) UWZ48-L 110-127V ~ 60Hz

I opened the top panel to see the ballasts, there are 2 sets of 3.
And I think I found a wiring diagram. But no Voltage appears to be listed.

Does the 110V indicate this is a 110V bed? For some reason I was under the impression it was 220.
The line leading away from the bed is a 12-4 and the owners said this would be easy to wire to a plug, as they had it hard wired.
I am unsure where to locate the model of the bed and unsuccessful at finding a manual of any sorts.
Can any one offer assistance or direction on where to find info to hook this up?
Thanks in advance for any guidance

Is the line leading away from the bed an appliance cord or a Romex cable?

How are the wires of the cable attached to terminals or screws in the bed? Notably are one or more of the 4 wires not hooked to anythings?

The 110-127 volt marking tells me that it will run on a 120 volt circuit.

12-4 would be white, black, blue, red +ground if NMb. Is that what you mean? Are all the wires connected inside the tanning bed?

Hi, I think that 110/127 only refers to the Grassoni timer, with there being a 12/4 cable it seems it would be 120/240 volt supply,can you take a few pics of the inside control panel ,if there is one, so that we can see what you have?

Leading away from bed is romex cable labeled 12/4, this is what it had when it came out of salon.
I should mention there is a manual timer box wired, as well, with dial timer, that they said was functional.

Newbie question: Can I just add the pics as an attachment in this reply?
I tried in original post and it said "failed", do I need to follow guidelines to upload pics?

I will open the bottom of the bed, which is where the wires enter, is that where the voltage would be listed for bed?
The wiring diagram I saw, mentioned in original post, is in the canopy and appeared to indicate how the ballasts were wired.

I opened the canopy again to sweep out dust and replace a few missing screws.
Found ballast wiring diagram and the following tag:
TYPE No: 524 Canopy
Serial No.:
Voltage: 240 VAC, 60Hz, single phase with neutral
Total wattage 3145
Manu Date: 1995

Does this help with the electrical requirements?
Or do I need to dismantle the entire bottom half to find more information? Where would it typically be found?
I opened where the wiring enters the bed and nothing but what appears to be set of wires to connect to , similar to a dryer red/green/white, there is a ground hooked up.
Will try to post a couple photos.
Thanks for the help!

That doesn't make sense. No neutral for 240. Maybe they mean 240/120 volts. If you have a 30 amp 4 prong dryer receptacle you might try putting a 14-30 plug on the cord and seeing what happens. Can't guarantee you won't let the smoke out but that is my best guess. Post the pics before trying that. Disclaimer suggestion could damage the tanning bed.

I have included photos of the bed, wiring from the bed and the wiring that came attached to the bed from the salon(black).

I am looking for what size breaker and what type of plug (NEMA?) will be required (rather than hard wiring).

Wondering if the tag was for canopy only?
Would that make sense?

With 3145 watts it should run fine on a 20 amp circuit. (about 13 amps) You need 4 wires (black, red, white and green or bare) all #12.
