To prevent damage to the power supply, use a reverse-current- protection diode in series between the power supply and load.
  • Page 31 GETTING STARTED Grounding The output terminals of the PSW power supplies are isolated with respect to the protective grounding terminal. The insulation capacity of the load, the load cables and other connected devices must be taken into consideration when connected to the protective ground or when floating.
  • Page 32 PSW Series User Manual If the positive or negative terminal is connected Grounded output terminal to the protective ground terminal, the insulation capacity needed for the load and load cables is greatly reduced. The insulation capacity only needs to be greater than the maximum output voltage of the power supply with respect to ground.
