d) If any of the control signal input terminals (TC1-TC3) are NOT used, jumper them to 0V Terminal (TC4). 
e) Route wires from the drive and connect to the peripheral device. Refer to the drive technical manual for further 
information on use of shielded cable.
f)
Connect the option card ground wire (G1) to the drive’s ground terminal TB3 (12 for G5).
 
Important: Because the analog input is high-resolution, the voltage source accuracy of the analog input must be 
considered. To ensure accuracy, use a high-precision power supply for the voltage source. 
 
7. Adjustment. There are no adjustments to be made on the AI-040 option; however, the drive will have to be programmed
for the input requirement(s) of the remote device and the reversing or non-reversing requirement of the specific 
application. Refer to Figures 4 and 5, and Table 3. 
8. Reinstall and secure the drive’s front cover. 
9. Place this instruction sheet with the drive’s technical manual.
