PHOENIX GP2DPL Digital 2 HP Rotary Phase Converter
Power Requirements
- RULE OF THUMB: Make sure your power feeding your circuit breaker panel is enough. The KVA number should be at least the same or larger number of the HP of converter youFor an example 50 KVA 230 Volts, is enough power to start a 40 HP Phase Converter. 50 KVA 230 Volt is NOT large enough to start a 75 HP Rotary Phase Converter. But will be enough to start two 40 HP Rotary Phase Converters one at a time, and then pair together to Have a 80 HP Converter.
- Make sure the Phase Converter you are installing is large enough for your equipment, and you have the right voltage phase converter, our team at Phoenix Phase Converters can help you with this. at 800-417-6568.
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.
BREAKER SIZE REQUIREMENTS
- Make sure you have a big enough breaker for your main to handle the starting of the phase converter.
- Increase Copper Wire Size For Every 50 Feet And Round Up – For Breakers Use 2 Times the Full Load of the Equipment, for multiple equipment give our team a call we can help you size the
- You must use an Industrial Licensed Electrician
- Magnetic controls, single phase loads, or resistive loads must be energized by L1 and L2
- Follow your state codes, most state require a disconnect between the circuit breaker panel and the converter if over 50 feet.
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.
WIRE AND BREAKER SIZES (Volts 230)
- 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 stardard 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.
WIRE AND BREAKER SIZES (Volts 460)
- 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 stardard size breaker which would be 50 Amps two pole breaker.

Connecting a Transformer to a Phase Converter
When connecting a transformer to a phase converter, you must
have a disconnect or a AutoLink inbetween the phase converter and transformer,
the phase converter must not be started with any loads, that includes
transformers.
Combining Two or More Phase Converters together.
Checking for a Blown Capacitor
This should be preformed by an electrician, Capacitors may hold a electrical
charge, make sure the phase converter main breaker is off, remove the cover to
the capacitor holder, check all the (black capacitors) start caps, check
punctures in the film covering the hole.
Checking for Voltage Dropping while Powering ON the Phase Converter.
Most common reason for a phase converter not coming up to speed while trying to start is the voltage on your single phase line is dropping, On PL models you want to put a voltmeter on T1 and T2, check the voltage while trying to start the converter, if the voltage is dropping below 215 you could have problems start the phase converter. On NL models put your meter on L1 and L2, watch the video to resolve this issue.
