PAD-L Applied Operation 4-3
5. Connect an electrolytic capacitor (C) with a capacity of approx. 100 to
100,000
µ
F across the load terminals.
CAUTION
• Use a capacitor (C) whose withstand voltage is 120% or more of
the unit's rated voltage.

NOTE
• If the length of wiring to a load extends to 3 m or more, the phase shift caused
by the inductance and capacitance of the wiring becomes non-negligible,
thereby causing oscillation. In such cases, the capacitor (C) prevents
oscillation.
• If the load current changes suddenly to pulse form, the output voltage may
increase due to effects from the inductance components of the wiring. In such
cases, the capacitor (C) also prevents variations in output.

6. Recheck that the connections.
WARNING
• After connections are complete, install the output terminal cover.
CAUTION
• After using remote sensing, disconnect the sensing wires and
reinstall the shorting bars for remote sensing between the output
terminals and sensing terminals.
