PHOENIX GP7PL 7.5 HP Rotary Phase Converter

Product Information

Specifications

Model: GP7PL
Version: 1.1.0

Power Requirements

The power requirements for the GP7PL phase converter are as follows:

Verify the KVA size of the transformer with your electric company. The KVA number should be larger than the HP of the idler motor.
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.
If you don’t understand the SPEED setting, call us or a qualified electrician. Failure to turn off the unit may result in damage to the idler motor, which will not be covered under warranty.
Ensure compliance with local and state laws.

Wire and Breaker Sizes

The recommended wire and breaker sizes for the GP7PL phase converter are as follows:

SINGLE PHASE:
- 8 AWG MIN Copper under 50 feet
- IDLER MOTOR 10 MIN AWG COPPER
- BREAKER/FUSE: 20 MIN / 40 MAX

Connecting the Idler Motor Wires

To connect the idler motor wires, follow these instructions:

This is just an illustration of what wires get connected together. Do not use wire nuts, use bolt down lugs.
If you have 9 leads at the motor, click here.
If you have 12 leads at the motor, click here.

Installation

The GP7PL phase converter must be installed by an industrial licensed electrician. Follow these additional instructions:

For PL and PH models, the Motor Load Breaker should be twice the full load amps of your equipment.
For the Phase Converter Panel, use a Load Center, 3PH Breaker Panel, or Equipment.
For a 9 Wire Idler Motor, connect Lead 1 and 7 to L1, Lead 2 and 8 to L2, Lead 3 and 9 to L3, and Lead 4, 5, and 6 together.
For a Single Phase Circuit Breaker Panel, use a disconnect if your run is over 50 feet.
For a 230V Connection (NL and PL Models), use low voltage.
For a 460V Connection (NH and PH Models), use high voltage.

FAQ

Q: What is the model and version of the phase converter?

The model is GP7PL and the version is 1.1.0.

Q: What are the power requirements for the phase converter?

The power requirements include verifying the KVA size of the transformer, ensuring secure connections, and understanding the SPEED setting to prevent damage to the idler motor.

Q: What wire and breaker sizes should be used?

For single phase, use 8 AWG MIN Copper under 50 feet for wire size and a breaker/fuse of 20 MIN / 40 MAX. The idler motor should use a minimum of 10 AWG copper.

Q: How should the idler motor wires be connected?

Follow the provided illustrations and do not use wire nuts. Instead, use bolt down lugs. Depending on the number of leads at the motor, click the corresponding link for instructions.

Q: Can I install the phase converter myself?

CAUTION
READ INSTRUCTIONS BEFORE OPERATING

READ FIRST – BEFORE INSTALLATION

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 verify the KVA size of the transformer, that KVA number should be larger then the HP of the idler motor.
DO NOT use WIRE NUTS for any connection, use the bolt down lugs.
Check all make sure all connections even factory connections to the power block are secure, also recheck connections after a few week of using the converter.
When powering up the unit, if the idler does NOT come up to FULL SPEED, then shut the phase converter down right away. If you don’t understand then call us or a qualified electrician. if you do not turn the unit off you have a chance to damage the idler motor that will not be covered under warranty.
Must be installed by a license industrial electrician, our guidelines are not 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 amps size of the machine. Example if the equipment pulls 20 amps use a 40 amp breaker.
Sizing the equipment for multiple machine double the amp of the largest machine and add the the other machine that will run at the same time. Example; 20 AMP Lathe. 9 amp saw, 6 amp milling machine. 20 X 2 = 40 +9 + 6 = 45 amps, use the next standard size breaker which would be 50 Amps two pole breaker.
Use the chart to make sure you don’t go over or under the Minimum and maximum size allowed. For rural areas increase the minimum size breaker by 20% Click on the next picture to see this chart.

Mounting the Phase Converter Panel

Mount the enclosure first, to a non-vibrating surface, there are two options provided for mounting, next install the back plate with the four nuts provided. Mounting the phase converter panel near the breaker panel is recommended the larger wire is you single phase line, that is best to keep as short as possible. Every 50 feet you will need to increase the size of the single phase wire.
