Connecting Terminating Resistance
Connect the provided terminating resistance (220
W
1%) between the RDA
and RDB terminals of the last Commmunications Unit for RS-422. Do not
connect terminating resistance to any other Unit.

Wiring the Power Supply
Wire the power supply as shown in the following diagram.
Note
1.
The power supply provides power to the Communication Unit and all the
Sensors that are connected to it. Select a power supply for the Communi-
cation Unit so that it has sufficient capacity for the current consumption of
the Sensors.
2.
Do not remove the power supply connector.
Disconnecting the power supply connector and then accidentally connect-
ing the E3X-CN11 Master Connector to the Fiber Amplifier Sensor Com-
munication Unit or connecting the disconnected cables to the Fiber
Amplifier Unit may damage the Fiber Amplifier Sensor Communication
Unit or the Fiber Amplifier Unit.
