Depends on the unit- there is a twist lock 20 amp 120v NEMA plug, but that’s very unlikely to be what’s going on here. You probably need a 30 amp outlet at 240 volts, but be aware of what voltage this specific UPS runs on. If it’s 208, you may not be able to use it at all. If it’s 240, you can get an outlet installed to power it.
