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 12 - Table 15.
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 11.
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.

INSTALLATION
Mounting Your New Phase Perfect
Proper installation of the unit is important to the performance and normal operating life of
the unit. The unit should be installed in a location free from:
•Corrosive gases or liquids
•Excessive vibration
•Airborne metallic particles
Mount the unit to a solid, non-flammable surface capable of bearing the weight using the
mounting brackets provided with the unit. Model weights are found in Table 6 –Table 9.
Mounting Bracket Installation
For shipping purposes, mounting brackets may be installed upside down, or shipped
separately in a bag. If the mounting brackets are not installed in an upright position,
remove the mounting screws, turn to an upright position, and then fasten the screws tightly.
Proper Ventilation
To maintain air circulation for adequate cooling, minimum clearance around the unit must
be maintained. Allow six inches on each side and top, and at least 18 inches below.
Ensure air intake and exhaust openings are not obstructed. If the unit is mounted in a small
room, cabinet, or building, ensure there is adequate ventilation to provide sufficient cooling.
Service Entrance Equipment
Phase Perfect phase converters are suitable for use as service equipment when the
molded case circuit breaker (MCCB)/disconnect, service ground conductor terminal, and
grounding electrode conductor are factory installed and the converter is labeled “Suitable
for use as Service Equipment.” Consult local electrical code for installation guidance.
Source Branch Circuit Protection
If a circuit breaker is not factory installed, branch circuit protection must be installed in the
circuit sourcing the phase converter. See Table 10 for recommended circuit breaker sizing.
Fuses may be used for circuit protection, consult local electrical code for proper sizing.
Installation of a disconnection means within sight of the phase converter is recommended.

12 | Page
V2.0
Grounding
•Properly ground the phase converter according to local electrical code.
•Connect the ground lug to the branch circuit or service ground conductor.
•Ground the phase converter with an adequately sized conductor according to
local electrical code.
•Ground wire recommendations based on solid to semi-rigid stranded copper
wire.

Wire Sizing
Use Table 11 to find minimum guidelines on properly sizing input conductors according to
local electrical code. The voltage drop from the supply to the converter should be limited to
3% to ensure proper starting and operation of motor loads. Increase the wire gauge to
provide adequate voltage to the load. Ensure the wire gauge is suitable to the terminal
block.
Use the following formula to calculate line voltage drop.
  

Connecting the Load
Do not connect single-phase loads to the manufactured leg, T3. This places unnecessary
load on the phase converter and may violate electrical code in some areas. Apply overload
and short circuit protection to protect load side conductors, motors, and other attached
loads according to local electrical code. For some motor loads and wiring configurations
load side short circuit protection may not be required. Consult local electrical code for
guidance.
Important Note:
If the connected load requires a wye configured power source with a neutral connection,
the load must be connected to the phase converter using a delta-wye isolation transformer.
