You can connect up to two units.
Connecting the load (series operation)
Connect the load as shown below.
1
Turn off all the PWX series that you want to connect in series.
2
Remove the OUTPUT terminal covers.
p.19
3
Use load cables to connect unit 1 and unit 2 to the load or relay terminal
block.
Use load cables that have sufficient current capacity. Wire the load cables so that they
are as short as possible. If the voltage drop in the load cable is large, the difference in
electric potential between power supply units and the load effect become large.
4
Connect the cables to the output terminals of unit 1 and unit 2.
5
Connect the output terminal (positive or negative) of unit 1 or unit 2 to
the chassis terminal.
6
Attach the OUTPUT terminal cover.

WARNING
Risk of electric shock. Turn the POWER switch off before you touch the OUTPUT ter-
minals. Attach the OUTPUT terminal cover after you finish wiring the load.
CAUTION
When the load cables are distributed over longer distance, the phase shifting due to wiring
inductance and capacitance may go beyond the limit and result in oscillation. To prevent
such oscillation, connect an electrolytic capacitor with several hundreds to several tens of
thousands
μ
F across the load.
Use an electrolytic capacitor with a withstand voltage that is 120% or more of the total of the
rated output voltages of the PWX series that are connected in series.
