Phoenix Phase Converters Installation and Support Page
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 size or larger number of the HP of converter you have.
Example: 50 KVA 230 Volts is enough power to start a 40 HP Rotary Pase Converter, 50 KVA at 230 Volts 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 paired together to achieve a 80 HP Rotary Phase Converter.
Phase Converter Size: Make sure the Phase Converter you are installing is large enough to run your equipment, and you have the right single phase voltage for the converter, either a 230 volt input or a 460 volt input.
Read First.
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
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.
Breaker Type and Size.
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.
Mounting the Phase Converter Panel
It is recommended to install the phase converter closer to the circuit breaker panel keeping the single phase wire the shorter wire, and extend your three phase line. Install the enclosure on the wall then mount the back plate.
After mounting the back plate make sure all the factory connections are tight they can become loose during shipping or from handling the phase converter.

Connecting a Transformer
to a Phase Converter
When connecting a transformer to a phase converter, you must have a disconnect or a AutoLink in-
between the phase converter and transformer, the phase converter
must not be started with any loads, that includes transformers.
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.
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.
