Precautions
On Operation
Connect the phase advancing capacitor to the power supply before
the Current Converter.
There are cases in which a 100/110 V power supply can be used.
The main reason for using a 100/110 V power supply is to protect a
high-tension motor. With a high-voltage power supply, the voltage
must be reduced with a potential transformer. It is also possible to
use a 100/110 V power supply with the 2E-type (two function) relays.
Use a commercial frequency power supply only for the control power
supply.
The Motor Protective Relay cannot be connected to circuits contain-
ing thyristors, rectifiers, or VVVF inverters. See explanation under
the heading Use with Thyristors, Rectifiers, or VVVF Inverters,
below.
The Motor Protective Relay also cannot be used to detect an over-
current in an inching run, because the overcurrent detection circuit is
reset at every inching step.
When using an SE relay with a current requirement below 1 A,
increase the number of conductor runs through the holes in the Cur-
rent Converter.
Use a model SAO sensor for single-phase applications. Refer to the
SAO datasheet.

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.
Although there is no particular restriction on the mounting direction,
it is best to mount horizontally.
The recommended panel thickness for panel mounting is 1 to
3.2 mm.
Connections
Make sure that the polarity is correct when connecting the Current
Converter and relay.
When using a commercial current transformer with a high-tension or
low -voltage, high-capacity motor, pass the external wiring of the
secondary through the holes in the Current Converter.
When using as a 3E (3 function) relay, connect the three-phase volt-
age correctly, as with external connections.
When using as a 2E (2 function) relay, it is not necessary to connect
terminal 3 (W).
