    H5CX-L8SD Note: Depending on the wiring, unwanted current from the AC power supply may occasionally burn out internal parts. H5CX-A/-L (except for H5CX-A11/-A11S) models do not have a transformer. Therefore, the power supply and input circuit are not insulated. Refer to Safety Pre- cautions (H5CX-A/-L) on page 49 for wiring details.
