PHOENIX GP15PL 15 HP Rotary Phase Converter

Product Information

Specifications

Model: GP15NL
Power requirements: Single phase
Wire and breaker sizes: 4 AWG Copper under 50 feet for single phase, 8 AWG Copper for idler motor
Breaker/fuse size: Minimum 30 amps, Maximum 80 amps

Product Usage Instructions

Step 1: Power Requirements

Before installation, call your electric company to verify the KVA size of the transformer. The KVA number should be larger than the HP of the idler motor.

Step 2: Check Connections

Ensure that all connections, including factory connections to
the power block, are secure. Recheck connections after a few weeks of using the converter.

Step 3: Understanding Speed

If you experience any issues with the speed of the phase converter, shut it down immediately. If you do not understand how to address the issue, call the manufacturer 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.

Step 4: Determining Breaker Size

For motors, double the amp size of the machine. For example, if the equipment pulls 20 amps, use a 40 amp breaker.

To determine the breaker size for multiple machines running simultaneously, add up the amps of the largest machine and other machines that will run at the same time. For example, if you have a 20 AMP lathe, a 9 amp saw, and a 6 amp milling machine, the calculation would be: 20 x 2 = 40 + 9 + 6 = 45 amps. In this case, you would use the next standard size breaker, which would be a 50 Amps two-pole breaker.

For rural areas, increase the minimum size breaker by 20%.

Step 5: Connecting the Idler Motor Wires

Refer to the illustrations in the user manual for connecting the idler motor wires. Do not use wire nuts; use bolt-down lugs instead.

Step 6: Professional Installation

The product must be installed by a licensed industrial electrician. Ensure that the motor load breaker is sized twice the full load amps of your equipment.

Step 7: Connection Types

For NL and PL models (low voltage), use a 230V connection. For NH and PH models (high voltage), use a 460V connection.

Frequently Asked Questions

Q: What is the power requirement for this product?

A: The power requirement is single phase.

Q: What wire and breaker sizes should I use?

A: For single phase, use 4 AWG Copper under 50 feet. For the idler motor, use 8 AWG Copper. The breaker/fuse size should be a minimum of 30 amps and a maximum of 80 amps.

Q: Can I use wire nuts to connect the idler motor wires?

A: No, wire nuts should not be used. Instead, use bolt-down lugs.

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.
