The I/O terminals are located in the center of
the wiring compartment, as shown previously in
Figure9.
The Digital Input connections (I1 and I2) are used to
control the Drive based on the state of an external
device, such as a flow switch, moisture sensor,
alternator, or other device. Programming is needed
to activate any of these functions (see Table 5).
The Output Relay (O1) is used to control an external

3. Insert wires from bottom
4. Release spring terminal
Connection Examples
Figures 15-18 show various connection schemes
for typical applications. Table 6 describes each I/O
