Read First - Before Installation
- [Important] Most important step to know.
- [Never] Start the phase converter with a load, this includes transformers.
- Make sure you have the incoming service to start the phase converter. Call your electric company to verify the KVA size of the transformer; that KVA number should be larger than the HP of the idler motor.
- [Do Not] Use WIRE NUTS for any connection; use the bolt down lugs.
- Check all connections, including factory connections to the power block, to ensure they are secure. Recheck connections after a few weeks of using the converter.
- [When powering up] If the idler does not come up to FULL SPEED, shut the phase converter down right away.
- If you do not understand, call Phoenix Phase Converters or a qualified electrician. If you do not turn the unit off, you risk damaging the idler motor, which will not be covered under warranty.
- [Must be installed] By a licensed industrial electrician. Our guidelines do not supersede local and state laws.
Power Requirements
- [You will need] To 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 amp size of the machine. Example: If the equipment pulls 20 amps, use a 40 amp breaker.
- [Sizing the equipment] For multiple machines, double the amp of the largest machine and add the amps of other machines that will run at the same time. Example: 20 AMP Lathe, 9 amp saw, 6 amp milling machine. Calculation: (20 AMP x 2) + 9 AMP + 6 AMP = 40 + 9 + 6 = 45 amps. Use the next standard size breaker, which would be a 50 Amp two-pole breaker.
- [Use the chart] To ensure you do not go over or under the minimum and maximum sizes allowed. For rural areas, increase the minimum breaker size by 20%. Click on the next picture to see this chart.

Connecting the Idler Motor Wires
This is just an illustration of what wires get connected together. Do not use wire nuts; use bolt down lugs.

Installation Diagram and Wiring
Must be installed by a licensed industrial electrician.
PL and PH Models
Motor Load Breaker should be sized twice the full load amps of your equipment.
The diagram illustrates the electrical connections for the phase converter. It shows a single-phase input circuit breaker panel connecting to the phase converter panel, which then outputs three-phase power to a load center, 3-phase breaker panel, or equipment. A disconnect switch is recommended for runs over 50 feet.
Wiring for 9 Wire Idler Motor: Lead 1, 7 to L1. Lead 2, 8 to L2. Lead 3, 9 to L3. Lead 4, 5, 6 together.
Wiring for 12 Wire Idler Motor: Lead 1, 7, 6, 12 to L1. Lead 2, 4, 10, 12 to L2. Lead 3, 5, 9, 11 to L3.
Connections:
- 230V Connection: For NL and PL Models (low voltage).
- 460V Connection: For NH and PH Models (high voltage).
