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%
