The UPS should be installed as a separately derived AC source using neutral and
ground wiring to preserve the fault tolerance specification of the DLm power

transformer/stabilizer installed in front of the UPS could further buffer the AC
utility environmental factors from reaching DLm. To determine if an isolation
transformer/stabilizer is needed, consult a licensed electrician.
