About This Guide
This procedure is a supplement to and to be used in conjunction with the Installation and Operation Manual for the SP500 Manual for the SP500 AC Controller I/M D233041. The procedure is meant to explain and condense the installation and operation manual to the basic and most used applications.
Input Voltage and Motor wiring should be sized in accordance with NEC/CEC and all other local codes. Input fuses should be provided to meet NEC/CEC and all other local codes. Suggested protection is a fused disconnect as described in Section 3.7 of the I/M.
Threephase incoming AC shall be wired to terminals R, S and T (as shown in figures 1 & 2). Singlephase AC shall be wired to terminals R and S. AC input wiring, motor wiring and control wiring should be run in separate conduits. Drive chassis ground and motor frame ground wires should be tied to earth ground.

Record drive and motor nameplate information including RPM, FLA and HP. Check the drive and motor wiring, with an ohmeter on the highest scale, for grounds. The ohmeter should read in the Megaohm range or totally open. Check that the incoming AC power is appropriate for the voltage as stated on the nameplate of the drive.
With motor not
wired to the drive, apply power. Drive will go through
its own software selftesting procedure for
approximately 5 seconds, and then display on the keypad
0.00. At this point you can press the start key on the
Turn off power, allow bus storage capacitors to discharge by letting drive sit without power for 5 minutes or check DC voltage on +/- terminals. Check motor wiring for the appropriate voltage. Wire motor to U, V and W (as per figure 1 and 2.)

Running the Drive
With motor disconnected from the mechanical load, reapply power and run the drive. With the drive in the local mode (from the keypad), remote led off, press start key and observe motor rotation. If motor rotation is incorrect, turn off power and let bus caps discharge as above, change any two motor leads (at U, V and W).
Run motor up and
down the speed range by pressing up/down arrow keys.
Connect motor to mechanical load and run drive throughout
speed range. Check monitor rpm, percentage load and
voltage using mode/enter key. Check calculation in
software section for function F14 motor thermal
If the application requires remote start/stop or analog speed reference read Section 5.0 Adjusting the Values of Drive Functions and Typical Wiring Diagrams, Section 3.0Installation and Wiring.
For most local applications default values are acceptable as listed on the attached parameter list.
