IC-TFU Installation Guide
Installation Step #1 – Connect IC-TFU Output wires to a DC Latching
Solenoid
The IC-TFU device provides control output pulses in response to Rain Bird IC System
TM
commands
received from the Rain Bird central control computer. IC-TFU control output pulses are suitable
for activating and deactivating a large number of DC latching solenoids.
1.
Strip approximately 1” of insulation from each DC Latching Solenoid connection wire
to be spliced with IC-TFU output control wires. Take care not to score copper
conductors.
2.
Splice / join wires by wrapping IC-TFU wires around DC Latching Solenoid Wires.

a.
Connect IC-TFU Output (+) (red-with-white stripe) wire to latching solenoid (+)
control input. (red wire)
b.
Connect IC-TFU Output (-) (black-with-white stripe) wire to latching solenoid (-
) control input. (black wire)
c.
Trim joined wires to the appropriate length for the wire nuts.
