GP30NL 30 HP Rotary Phase Converter
Installation and Operation Guide
Important Notes & Warnings
READ FIRST - BEFORE INSTALLATION
? Most important step to know.
NEVER start the phase converter with a load, this includes transformers.
Ensure incoming service is adequate. Call 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 does NOT come up to FULL SPEED, shut the phase converter down immediately. If you do not understand, call 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. Guidelines do not supersede local and state laws.
Power Requirements
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. Example: if the equipment pulls 20 amps, use a 40 amp breaker.
Sizing the equipment for multiple machines: Double the amp of the largest machine and add the other machines that will run at the same time. Example: 20 AMP Lathe, 9 amp saw, 6 amp milling machine. Calculation: 20 AMP 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 ensure you do not go over or under the minimum and maximum size allowed. For rural areas, increase the minimum size breaker by 20%.
Refer to the chart for wire and breaker sizes.
