Bypass Aux Inputs; Enable Vfd Mode; Voltage Calibration - Phase Technology PERFECT PT007 Operation & Installation Manual

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. In this
mode, the output voltage may not be balanced. This function is typically used to prevent
overheating of the VFD due to unbalanced currents induced by the non-linear nature of the
VFD inverter. Turn power to the unit off and set DIP switch 10 to the ON position to enable
VFD mode.

Voltage Calibration

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.
Calibrating voltage will require wiring two ON/OFF switches to the converter. Standard light
switches will work. See Figure 24 below, for wiring diagram.
To adjust output voltage, follow the steps below:
