PHOENIX GP50NL 50 HP Rotary Phase Converter Installation Guide

PHOENIX GP50NL 50 HP Rotary Phase Converter

Product Information

Specifications

• Model: GP50NL
• Power requirements: Single phase
• Idler motor size: 1 AWG Copper
• Breaker/Fuse size: Minimum 80 Amp / Maximum 250 Amp

Product Usage Instructions

1. Power Requirements

Before installation, make sure to verify the KVA size of the transformer with your electric company. The KVA number should be larger than the HP (Horsepower) of the idler motor.

2. Checking Connections

Check all connections, including factory connections to the power block, to ensure they are secure. It is recommended to recheck connections after a few weeks of using the converter.

3. Power Connections

When connecting the phase converter, it is important to follow local and state laws. Use a quick blow or trip breaker for protection. For motors, double the amp size of the machine. For example, if the equipment pulls 20 amps, use a 40 amp breaker. When running multiple machines simultaneously, calculate the total amps by adding the amps of the largest machine and the other machines that will run at the same time. Use the next standard size breaker for this total amp value.

Example:

20 AMP Lathe + 9 AMP Saw + 6 AMP Milling Machine = 35 amps Use a 40 Amps two- pole breaker for this example.

4. Wire and Breaker Sizes

For single-phase connections:

• 3/0 AWG Copper under 50 feet

For the idler motor, use 1 AWG Copper wire. For the breaker/fuse, use a minimum of 80 Amp and a maximum of 250 Amp.

5. Connecting the Idler Motor Wires

Follow the provided illustrations for connecting the idler motor wires. Do not use wire nuts, instead, use bolt down lugs.

If you have 9 leads at the motor, follow the instructions provided in the manual.

If you have 12 leads at the motor, follow the instructions provided in the manual.

6. Installation by a Licensed Electrician

This product must be installed by an industrial licensed electrician to ensure proper installation and safety.

7. Connection for NL and PL Models

For NL Models (low voltage), use a 230V connection.

For PL Models (high voltage), use a 460V connection.

READ FIRST – BEFORE INSTALLATION

• A 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.
