Operation
Remote Sensing Function
This function corrects a voltage drop in the load wiring. When using
the remote sensing function, remove the short bars from the remote
sensing terminals as shown in the following diagram.

Note:
1. When the voltage drop in the load wiring is large, the
overvoltage protection function might engage just from
the increase in voltage to correct the voltage drop, so be
sure to use high capacity wiring.
2. If the +S and +V terminals are left unconnected, the high
voltage protection function will engage and the output
voltage will be cut off. If the -S and -V terminals are left
unconnected, the output voltage will increase about 5%.
Remote Control Function
This function allows the output voltage to be turned on and off with
an external signal (as long as the input voltage is being applied).
When using the remote control function, remove the short bar (at-
tached at ex-factory condition) from the remote control terminals
and connect a switch or transistor as shown in the diagram below.

Fan Alarm
When the speed of the internal fan drops, the fan alarm output
(SPST-NO) will turn ON (shorted).
