Phoenix Phase Converters GP50NL 50 HP Rotary Phase Converter
Read First - Before Installation
- ? Most important step to know.
- ? NEVER start the phase converter with a load, this includes transformers.
- ? Ensure you have the incoming service to start the phase converter. Contact 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 the unit, if the idler motor does NOT come up to FULL SPEED, shut the phase converter down immediately. If you do not understand the procedure, contact Phoenix Phase Converters or a qualified electrician. Failure to turn the unit off may damage the idler motor, which will not be covered under warranty.
- ? Must be installed by a licensed industrial electrician. These guidelines are not intended to 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. 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 draw of other machines that will run simultaneously. Example: 20 AMP Lathe, 9 amp saw, 6 amp milling machine. Calculation: (20 AMP x 2) + 9 AMP + 6 AMP = 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%.
Wiring and Connections
Wire and Breaker Sizes
| Single Phase Idler Motor | Wire Size | Breaker/Fuse Size (Amps) |

Connecting the Idler Motor Wires
This is an illustration of how wires are connected. Do not use wire nuts; use bolt-down lugs.
For motors with 9 leads, refer to specific wiring instructions.
For motors with 12 leads, refer to specific wiring instructions.
Installation Guidelines
Must be installed by a licensed industrial electrician. These guidelines do not supersede local and state laws.
PL and PH Models: Motor Load Breaker should be sized twice the full load amps of your equipment.
Connections are made to the Phase Converter Panel, Load Center, 3PH Breaker Panel, or Equipment.
A Single Phase Circuit Breaker Panel is used.
A disconnect should be used if your run is over 50 feet.
Voltage Connections:
- 230V Connection for NL and PL Models (low voltage).
- 460V Connection for NH and PH Models (high voltage).
Wiring Configurations:
- 9 Wire Idler Motor: Connect Lead 1, 7 to L1. Connect Lead 2, 8 to L2. Connect Lead 3, 9 to L3. Connect Leads 4, 5, 6 together.
- 12 Wire Idler Motor: Connect Lead 1, 7, 6, 12 to L1. Connect Lead 2, 4, 10, 12 to L2. Connect Lead 3, 5, 9, 11 to L3.
Dimensions
