I/O Connections 16
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 9).
The Output Relay (O1) is used to control an external
device based on two states of Drive; either Running
the pump or Faulted.
Programming is needed to activate any of these
functions (see Table 9).
Cable Installation
Three 13mm conduit knockouts are provided
on the bottom of the Drive enclosure for the I/O
wires.
Break out the closest 13mm knockout and route
the wires through. Use a cord grip to prevent the
wire from rubbing and causing a short.
NOTICE Never run low voltage I/O wire through
the same conduit hole as the 230V input wires or
motor wires.
To connect the external wires to the terminals:
1. Strip wire 13mm
2. Push spring terminal up with finger or slotted
screwdriver
3. Insert wires from bottom
4. Release spring terminal
Connection Examples
Figures 15-18 show various connection schemes
for typical applications. Table 10 describes each
I/O terminal, including purpose and rating.
