Breaker/Fuse: 30 MIN / 80 MAX

Product Usage Instructions

Power Requirements

Before installation, it is important 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. This is to ensure proper functionality and avoid damage to the motor.

Connections and Safety

Check all connections, including factory connections to the power block, and ensure they are secure. It is recommended to recheck the connections after a few weeks of using the converter to ensure everything is still properly connected.
If you experience any issues with the speed of the phase converter, it is important to shut it down immediately. If you are unsure of what to do, contact 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.
Always follow local and state laws when using the product.

Breaker and Wire Sizes

For proper installation, it is recommended to use a breaker that is double the amps size of the machine. For example, if the equipment pulls 20 amps, use a 40 amp breaker.
If multiple machines will be running simultaneously, calculate the total amps required by adding the amps of the largest machine to the amps of the other machines. For example, if you have a 20 AMP lathe, a 9 amp saw, and a 6 amp milling machine, the total would be 20 X 2 = 40 + 9 + 6 = 55 amps. In this case, you would need to use the next standard size breaker, which would be a 50 Amps two-pole breaker.
For rural areas, it is recommended to increase the minimum size breaker by 20%.

Wire and Breaker Sizes

The recommended wire and breaker sizes for single-phase setup are as follows:

4 AWG Copper for distances under 50 feet

Connecting the Idler Motor Wires

When connecting the idler motor wires, it is important to follow the correct wiring configuration. If you have 9 leads at the motor, refer to the appropriate instructions. If you have 12 leads at the motor, follow the instructions below:

12 Wire Idler Motor:

Lead 1, 7, 6, and 12 to L1
Lead 2, 4, 10, and 12 to L2
Lead 3, 5, 9, and 11 to L3

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.
