• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Precautions
On Operation
Use a commercial frequency power supply only for the control power
supply.
The SET-3@ Current Converter is designed for use with a single
SAO Current Sensor; do not connect two units to a single SET-3@ as
in figure 1 below (even if a diode is included in the circuit).
If the current transformer has sufficient capacity, the circuit in figure 2
is acceptable.
Mounting
When installing with an 8PFA1 connecting socket, first fasten the
socket firmly to the panel with screws, then plug in the relay and
secure it with a hook. Leave at least 30 mm of space between the
relays for the hooks.

Connections
Make sure that the polarity is correct when connecting the Current
Converter and Current Sensor. It is not necessary to consider polar-
ity when using a DC control power supply.
Determine the necessary number of conductor runs from the table
Selecting the Current Converter in the Operation section. Pass the
wires through the holes from the same direction. It doesn’t matter
which wires go through which holes.
Testing Method
Verify operation by turning on the control voltage and pressing the
test button.
It is possible to check whether SAO-@ and SET-3@ characteristics
are correct or not with the test circuit shown on page 6.
One conductor pass Four conductor passes
(The conductors pass
through the holes once.)
Current Sensor
(The conductors pass
through the holes four times.)
