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.

CAUTION The front and rear output terminals are
electrically connected internally. Terminals that
are NOT in use still carry output voltage.
Be careful not to touch the terminals. Failure to
heed this warning may result in electric shock.
