• Ensure input power connections are properly
torqued.
• Route control wiring to the drive. Use shielded cable
for control wiring.
• Do not run control wiring in the same conduit as
power wiring.
• Connect the control wires by using a flat blade
screwdriver to open the spring terminal as shown.
• Hold the spring terminal open and insert the control
wire. Release the screwdriver to close the spring
terminal and secure the connection.
REQUIRED CONNECTION: The factory default set-
tings for the controller require a start signal on DI18.
NOTE: If using a transducer for feedback, set the
analog input configuration switches A53 (AI53)
or A54 (AI54) under the keypad.
