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.
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.

Connecting Source Power Table 17 – Input Wiring Wire size recommendations based on 600 VAC copper wire, rated either 60°C or 75°C. Assuming 104°F (40°C) ambient and no more than 3 current carrying conductors in raceway or earth (directly buried). If phase converter will be in warmer environments, consult NEC Handbook for temperature correction factor.
Generator Power Phase Perfect phase converters can be powered by a generator, but it is recommended that generator be sized 150% of the phase converter rating for proper operation. If a generator will be used for backup power, a delay timer must be used to allow the phase converter to completely shut down before transferring to a new power source.
Figure 11 – PTS Field Wiring Terminals: Figure 12 – PTS Field Wiring Terminals: PTS003, PTS005, PTS007 PTS405, PTS407 Routing Power Cables Note: Continuous metal conduit should be used for all power cables to reduce radiated electromagnetic interference (EMI). The conduit must be securely grounded to the converter enclosure and the motor case.
On/Off Control Wiring The output of the converter can be controlled with a switch connected between the AUX1 or AUX2 and COM terminals. If installed, remove the factory installed jumper wire and replace with a switch. Jumper wire can be seen in Figure 19 below. Factory-installed jumper wire from AUX1 to COM...

WARNING! When the converter is turned OFF using a switch on the AUX terminals, dangerous voltage may still be present on the input lines and elsewhere inside the enclosure. Never open the enclosure or perform maintenance on the unit or connected loads when the incoming power to the phase converter is ON, regardless of the switch setting.
OPERATION LCD Status Screen When the unit is powered up, the screen will scroll through the operating parameters. Figure 21 – Status Screen Figure 22 – “System Off” Status Screen DIP Switch Settings WARNING! Make sure the input power disconnect switch is in the OFF position before opening the front cover to the unit.
Bypass AUX Inputs When both DIP switches 9 and 10 are in the ON position, AUX1 and AUX2 inputs will be bypassed causing the output to energize regardless of the state of AUX1 and AUX2. Enable VFD Mode In VFD mode the phase converter will automatically adjust the current on the generated leg to balance the three-phase currents by adjusting the voltage of the generated leg.
Toggle SW4 to move between ADJUST V23 and ADJUST V31. When the desired parameter is shown on the display, toggle SW3 OFF then ON to enter the selected menu. Action Effect Toggle SW3 Decrease selected voltage Toggle SW4 Increase selected voltage When adjusting output voltage, make changes in small increments (5 V or less) to begin, then let the menu time out to save the change.
Elevator Mode 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. WARNING! Using Elevator Mode on any application except an elevator will void manufacturer’s warranty.
Startup Delay 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. Startup Delay will force the converter to wait for a set time period before starting up. This procedure will require wiring two ON/OFF switches to the converter.
Infinite Restarts 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. Infinite Restarts will allow the converter to restart an unlimited number of times after fault conditions.
Fault Codes Table 29 – Fault Codes Text Description/Comments Restart Sudden and severe regenerative power under high BUS OVERVOLTAGE Auto line voltage may result in bus overvoltage. CLASS 4 OVERLOAD Output current exceeded operating limit. Auto Connection from Control board to Hall Sensor isn’t CM BOARD FAULT properly connected.
Faults: Manual Restart These faults generally indicate damage to the converter and/or the load. They may also indicate a potentially dangerous condition. When this type of fault occurs, the display will indicate the fault message and the converter output will remain off. CAUTION! Contact Phase Technologies for assistance before restarting or troubleshoot the system thoroughly before power cycling the converter.
TROUBLESHOOTING TIPS If a fault occurs, a fault code will be displayed on the LCD screen. See Table 29 for a list of fault codes. Fault codes generally indicate that an issue exists independent of the phase converter. Table 31 – Troubleshooting Problem Potential Cause Solution...
ROUTINE INSPECTION AND MAINTENANCE 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 only be installed and serviced by trained and licensed personnel. Follow instructions carefully and observe all warnings.

For 460V PTE models (PTE4XX), disconnect wires from JL2. You may need to remove the baffle covering the heatsink to access JL2. Next, use a multi-meter to measure between L1 and L2, then measure between L2 and JL3B. If either capacitance measured is below the 50% Capacitance value in Table 32, contact Phase Technologies for replacement.
