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. - Page 18 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.

Page 21: Routing Power Cables
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 converter and the motor case. Route power cables through the supplied openings in the bottom of the enclosure, using appropriate conduit or strain relief devices. -
Page 22: On/Off Control Wiring
ON/OFF Control Wiring The output of the converter can be controlled with a low power switch connected between the AUX1 or AUX2 and COM terminals. If installed, remove the factory installed jumper wire and replace with a switch. See Figure 17. When AUX1 to COM or AUX2 to COM is closed, the output is energized after a delay of approximately two seconds. -

Page 24: Dip Switch Settings
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. In this mode the output voltage may not be balanced. This function is typically used with some VFDs to prevent overheating of the VFD due to imbalanced currents induced by the non- linear nature of the VFD inverter. -
Page 25: Faults With Auto-Restart
Description/Comments Restart Check for short circuit on output lines and load. OUTPUT FAULT Manual Contact Phase Technologies. Check for short circuit on input lines. Contact Phase INPUT FAULT Manual Technologies. Internal temperature of the converter exceeded safe OVER TEMPERATURE operating limits. Check fans and ventilation openings Auto for obstruction. -
Page 26: Faults: Manual Restart
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. See additional descriptions of the faults in Table 15. -

Lightly brush and vacuum. Contact Customer Service for assistance in replacing cooling fans. Use only fans approved by Phase Technologies. Unapproved fans may lead to component damage. Line Filter Capacitors Line filter capacitors are part of the inductor/capacitor (L/C) filters and should be routinely monitored and replaced if degraded. - Page 29 If the capacitance of either is below the 70% Capacitance value in Table 18, contact Phase Technologies for replacement. For PT Medium and Large Frames, use a multi-meter to measure between L1 and L2, then measure between L2 and L3.
