Supplying power to the sensor amplier
The power terminal block is mounted on the bottom of the
sensoramplier.
Use wire whose temperature rating is 80 ºC or
higher for the power supply.
Follow the instructions mentioned below to
avoid damage caused by bad connections.

The nominal cross-sectional area of the wire
for connecting the power should be 0.8 mm
2
to 1.3 mm
2
(AWG16 to 18).

Length of the insulation removed from the
wire should be around 9mm.

The stripped part of the wire should not be
soldered (pre-soldered).

Insert the wires to the power terminal block
completely.

Wire the power cables directly into the
terminal block.

Use a rod terminal when using a crimp-type
terminal.
