Installation Warnings
A prominent yellow and black 'CAUTION' sign with the text 'READ INSTRUCTIONS BEFORE OPERATING' is displayed.
Read First - Before Installation
- Most important step to know.
- NEVER start the phase converter with a load, including transformers.
- Ensure incoming service is adequate. Call your electric company to verify the transformer's KVA size; it must 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, for security. Recheck connections after a few weeks of use.
- If the idler motor does NOT reach FULL SPEED when powering up the unit, shut the phase converter down immediately. If you are unsure, contact Phoenix Phase Converters or a qualified electrician. Failure to shut down the unit may damage the idler motor, which will not be covered under warranty.
- Installation must be performed by a licensed industrial electrician. These guidelines do not supersede local and state laws.
Power Requirements
Note: You will need to use a motor load type breaker. NOT a quick blow or trip breaker.
Breaker and Wire Sizing
- 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 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 X 2) + 9 + 6 = 40 + 9 + 6 = 55 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 size allowed. For rural areas, increase the minimum size breaker by 20%.

| Wire Size | 6 AWG Copper under 50 feet | 8 AWG COPPER | 20 MIN / 40 MAX |
Mounting the Phase Converter Panel
Mount the enclosure first, to a non-vibrating surface. Two mounting options are provided. Next, install the back plate with the four nuts provided. Mounting the phase converter panel near the breaker panel is recommended for the single-phase line, keeping it as short as possible. Every 50 feet, you will need to increase the size of the single-phase wire.

A graphic highlights the enclosure's IP65 WATERPROOF & WEATHERPROOF rating, indicating suitability for indoor or outdoor installation.
Connecting the Idler Motor Wires
Important: THIS IS JUST AN ILLUSTRATION OF WHAT WIRES GET CONNECTED TOGETHER. DO NOT USE WIRE NUTS, USE BOLT DOWN LUGS.

Two detailed photographic illustrations show the wiring connections for the idler motor. One illustrates connections for a motor with 9 leads, and the other for a motor with 12 leads, indicating which leads connect to L1, L2, and L3 terminals. The text emphasizes using bolt-down lugs and avoiding wire nuts.
Wiring Diagram (PL and PH Models)
MUST BE INSTALLED BY A INDUSTRIAL LICENSED ELECTRICIAN
A comprehensive wiring diagram illustrates the electrical connections for PL and PH models. It shows the flow from a single-phase circuit breaker panel, through a disconnect switch (recommended for runs over 50 feet), to the phase converter panel, and finally to the idler/generator motor. The diagram specifies wire gauges (6 AWG Copper for runs under 50 feet, 8 AWG Copper for the idler motor) and breaker sizing recommendations. It also notes the location of wiring diagrams on the name plate or inside the connection cover and provides specific connection details for 9-lead and 12-lead idler motors.
Wiring Notes 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 Notes 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.
The diagram indicates the use of 6 AWG Copper for runs under 50 feet and 8 AWG Copper for the idler motor. The Motor Load Breaker should be sized twice the full load amps of your equipment. A disconnect should be used if your run is over 50 feet.
Dimensional Specifications
Technical engineering drawings provide detailed dimensional specifications for the idler motor. These include overall length, height, width, mounting hole patterns, and conduit connection details. A warning label states 'ISOLATE CIRCUIT BEFORE REMOVAL'.
