9.4.5.4 Output Wiring
The EOS-1 or EOS-3 is wired in series with the output of specified California Instruments power
systems. The EOS terminal block marked SOURCE should be wired to the output of the power
source/system. The terminal block marked LOAD is wired to the user's load. Refer to
Figure 9-36 and Figure 9-37 in this section for examples of proper connections. Refer to Section
3.5 to determine the appropriate wire gauge needed for the output wiring.
Note in Figure 9-36 the sequence of instruments. This is the recommended sequence between
the iX source and the equipment under test. For systems that do not include all the instruments
shown, maintain the sequence of the remaining instruments.
Note also that for all applications the remote sense wiring must be connected before the EOS
unit.
Note: The output voltage of the iX/i-series power sources into the EOS box may
be at hazardous potentials as high as 300 volts line to neutral (600 volts line to line).
Wiring used between the power sources and the EOS and between the EOS and the
user’s load must be insulated to withstand this potential.
Note: The SOURCE and LOAD terminals of the EOS will be at the hazardous live
potentials of the iX/i-series power sources driving it even if EOS box has not been
switched on.
