CAUTION
Noise at the load end may be reduced by twisting
the cables to the load or connecting a film
capacitor (low impedance, high-frequency, several
μF) and an electrolytic capacitor (sev
eral hundred
μF) to the load end.

Note
The negative potential of the external voltage
control is the same as that of the negative output
terminal. If the power supply unit is grounded at
the positive terminal and the power source for
external control is grounded at the negative
terminal, the load cables for external voltage control
will short-circuit the output of the power supply
unit, which could damage the unit. In this situation,
make sure the external voltage control source is
floating with respect to the output terminals.
