Safety Considerations
This power supply is a Safety Class I instrument, which means that it has a
protective earth terminal. That terminal must be connected to earth ground
through a power source with a 3-wire ground receptacle.
Before installation or operation, check the power supply and review this
manual for safety markings and instructions. Safety information for specific
procedures is located at the appropriate places in this manual. See also
‘‘Safety’’ at the beginning of this manual for general safety information.
