GP40NL Rotary Phase Converter
Installation Guide and Component Overview
Read First - Before Installation
- Never start the phase converter with a load connected, including transformers.
- Ensure incoming service is adequate. Contact your electric company to verify the KVA size of the transformer; it must be larger than the HP of the idler motor.
- Do not use wire nuts for any connection; use the bolt-down lugs provided.
- Check all connections, including factory connections to the power block, to ensure they are secure. Recheck connections after a few weeks of use.
- If the idler motor does not reach full speed upon powering up the unit, shut down the phase converter immediately. Failure to do so may damage the idler motor, which will not be covered under warranty. If you are unsure, contact Phoenix Phase Converters or a qualified electrician.
- Installation must be performed by a licensed industrial electrician. These guidelines do not supersede local and state laws.
Power Requirements
- Use a motor load type breaker, not a quick blow or trip breaker.
- Sizing a breaker for a single machine with an inductive load (motors): Double the machine's amp size. For example, if the equipment pulls 20 amps, use a 40 amp breaker.
- Sizing the equipment for multiple machines: Double the amp size of the largest machine and add the amp requirements of other machines that will run simultaneously. For example, for a 20 AMP Lathe, a 9 amp saw, and a 6 amp milling machine: (20 AMPs x 2) + 9 AMPs + 6 AMPs = 40 + 9 + 6 = 55 AMPs. Use the next standard size breaker, which would be a 50 AMPs two-pole breaker.
- Refer to the chart below to ensure you do not exceed the minimum and maximum breaker sizes allowed.
- For rural areas, increase the minimum breaker size by 20%.
A chart detailing minimum and maximum breaker sizes is referenced in the original document. For rural areas, it is recommended to increase the minimum breaker size by 20%.
Wire and Breaker Sizing (GP40)
| Description | Specification |

Connecting the Idler Motor Wires
The following describes how wires should be connected. Do not use wire nuts; use bolt-down lugs.
For motors with 9 leads, consult specific wiring diagrams.
For motors with 12 leads, follow these connections:
- Connect leads 1, 7, 6, and 12 to L1.
- Connect leads 2, 4, 10, and 12 to L2.
- Connect leads 3, 5, 9, and 11 to L3.
