Transformer Power Test Procedure
1.Make sure that transformer wires are connected to the drive board at the CN2 connector.
2. Put the multimeter on the 500 VAC setting. Turn on unit power.
3. Put multimeter probes on like-colored wires, starting with the two red wires (120V markets), or the two
blue wires (220V markets), as shown below. These are the primary (input) wires.
4. Normal reading: 110 VAC (N. America) or 220 VAC (Europe). Transformer voltage input = wall power.
5. Test other like-colored wires in order as indicated below. These are the secondary (output) wires.
Troubleshooting
1. If there is no input voltage, inspect the on/off switch, the fuse, the power cable connections, and power
at the wall.
2. If there is input but no output, the transformer is bad. Replace it.
