Dear TanningBeds.org,

My wife just bought a sonnenbraune wolff 524 tanning bed that had been hardwired in at it’s former home. I need to know what the wires are for so that i can wire it in. It has 4 wires red, white, green, and black. I have been unable to locate a wiring diagram anywhere. any help would be appreciated

I have heard that they recently went out of business, so getting a manual may be tough. Fortunately, I used to work on and sell those beds. Wiring is a piece of cake. The red and black are HOT, the white is Neutral, the green is ground. It needs a 30 amp, 4 wire connection.

Not all SonnenBraune beds use this wiring scheme, but many 4 wire tanning beds do, including the SonnenBraune 524 (but NOT the 524E and 524ES), 624, 728, 732 as well as SunDash R26, R32, Montego Bay Wolff 24, plus the 2400, 2600, 2800, and 3200 Classic and Legend beds. Same for most Tan America beds and many other US made beds, even new SunMaster 32s.

Don’t use a 3 wire and combine the white and green, which may *sorta* work. All the electronics in that bed are actually 120V, it uses the two hots to power the different halves of the bed. This is why it needs the neutral, and this is why it needs to be 30 amp. The hots only need 20 amp, but the shared neutral pushes the electrical requirements up to a 30 amp circuit (usually 10 gauge wire).

Remember this when you buy fans, timers, relays, etc as well, since they will actually be 120V and not 240V.
