Setup Checklist
As an option, the drive and motor could be set up on a test bench before installation, by following
the Start-up Procedure.
1. Remove all interface wiring.
2. Remove the cover and set jumpers P6 through P9A. See Figure 2.1 on page 2-2 and
“Internal Connections (FAC, RAC and INH)” on page 2-11.
3. Verify that fuses F1 and F2 are good. See “Checking and Replacing the Fuses” on
page 4-2.
4. Ensure transformer is sized correctly for the application. Refer to “Transformer Sizing”
on page 2-3.
5. Verify the transformer selected can provide enough voltage for the application. This can
be determined by looking at the maximum speed of the application and the voltage
constant (K
E
) of the motor selected.
6. Check that the incoming AC or DC voltage is correct.
Do not apply more than 85 VAC or 120 VDC to TB1 pins 6 and 7.
Verify fusing per wiring diagrams in “AC and DC Power Connections” on page 2-4.
7. Install drive. Refer to “Mounting” on page 2-3.
8. Replace cover.

WARNING
If the polarity of the tachometer is not connected to the drive correctly, the motor
will run away which could damage the load and may cause bodily injury.
