INTRODUCTION
The Phase Perfect®Digital Phase Converter converts single-phase AC power to
three-phase AC power to operate a variety of electrical equipment. The Phase Perfect®
delivers unmatched, three-phase voltage balance and operates at 98.7% efficiency.
Output voltage is sinusoidal with low harmonic content, making it safe to operate
sensitive electronic equipment. The Phase Perfect®was designed to comply with IEEE
519 to meet utility regulatory standards.
Phase Perfect®Digital Phase Converters are available in NEMA 1 indoor enclosures
and NEMA 3R outdoor enclosures with insect guards.

SAFETY MESSAGES AND WARNINGS
To ensure safe and reliable operation of the Phase Perfect®, it is important to carefully
read this manual and to observe all warning labels attached to the unit before installing.
Please follow all instructions exactly and keep this manual with the unit for quick and
easy reference.
Definitions of Warning Signs and Symbols
CAUTION: Indicates a potentially hazardous situation that could result in injury or
damage to the product.
WARNING: Indicates a potentially hazardous situation that could result in serious
injury or death.
HIGH VOLTAGE: The voltage associated with the procedures referenced could
result in serious injury or death. Use caution and follow instructions carefully.
READ THESE WARNINGS BEFORE INSTALLING
OR OPERATING EQUIPMENT!
WARNING: Risk of electric shock. More than one disconnect switch may be
required to de-energize the equipment before servicing.
WARNING: Risk of electric shock. De-energize the unit by disconnecting all
incoming sources of power, then wait 30 minutes for internal charges to dissipate
before servicing the equipment.
HIGH VOLTAGE: This equipment is connected to line voltages that can create a
potentially hazardous situation. Electric shock could result in serious injury or death.
This device should be installed and serviced only by trained, licensed, and qualified
personnel. Follow instructions carefully and observe all warnings.
WARNING: Installation of this equipment must comply with the National Electrical
Code (NEC) and all applicable local codes. Failure to observe and comply with these
codes could result in risk of electric shock, fire, or damage to the equipment.
CAUTION: Circuit breakers, fuses, proper ground circuits, and other safety
equipment and their proper installation are not provided by Phase Technologies, LLC,
and are the responsibility of the end user.
CAUTION: Failure to maintain adequate clearance may lead to overheating of the
unit and cause damage or fire.

WARNING: Input power connections should be made by a qualified electrician
into circuit with adequate voltage and current carrying capacity for the model. Branch
circuit protection to the unit should be provided by appropriately sized fuses or a 2-pole
circuit breaker.
CAUTION: Use 600 V vinyl-sheathed wire or equivalent. The voltage drop of the
leads needs to be considered in determining wire size. Voltage drop is dependent on
wire length and gauge. Use only copper conductors.
CAUTION: Wires fastened to the terminal blocks shall be secured by tightening
the terminal screws to a torque value listed in Table 14 - Table 17.
CAUTION: The input wire gauge must be sized for the single-phase input current,
which will be significantly larger than the three-phase output current to the load. The
minimum wire gauge for the input terminals is listed in Table 13.
CAUTION: Never allow bare wire to contact metal surfaces.
CAUTION: Never connect AC main power to the output terminals T1, T2, and T3.
WARNING: Under certain conditions, the motor load may automatically restart
after a trip has stopped it. Make sure power to the converter has been disconnected
before approaching or servicing the equipment. Otherwise, serious injury may occur.

THEORY OF OPERATION
L1 and L2 of the single-phase input pass directly through the phase converter to provide
two legs of the three-phase output. The input module charges a DC bus from the input
lines. The output module uses power from the DC bus to generate the third leg of the three-
phase output. The third leg is generated to limit voltage imbalance between the three legs
to ≤ 2%. Voltage imbalance is calculated according to the NEMA MG1 standard.
