WARNING!
High voltage present! Risk of electrical shock. Do not remove cover. Refer
to qualified service personnel.
For permanently connected equipment, incorporate a readily accessible
disconnect device in the fixed wiring. For pluggable equipment, install the
socket outlet near the equipment and in an easily accessible location.
Table 2–1 lists all external connections for the SPS-A Series models.
Table 2–2 and Table 2–3 provide input and output connection
descriptions by power supply type. Section 2.8 provides a drawing of the
rear panel input/output connector locations.
CAUTION!
Proper connection to the mains requires a circuit breaker or fuse with a rating of
25% over the maximum input line currents listed in
WARNING!
Under no condition should the negative output terminal exceed 300V to earth
ground.
CAUTION!
Floating the negative output terminal floats the power supply's internal control
circuitry common level to the same potential as the negative output terminal. On a
standard non-isolated supply the common of the analog control connector (J1)
floats at the same potential as the negative output terminal. Damage may occur if
the non-isolated analog control connector of a supply is connected to an external
ground referenced input/output device. Such a connection creates ground loop
currents. To correct ground loop problems the Isolated Analog option is advised in
order to isolate the external ground reference signals from the internal control
circuitry of the supply.
Table 2–1 provides details of the SPS-A Series input and output
connectors and their functions. Table 2–2 describes the input connector
types and Table 2–3 describes the output connector types.
