Disable Auto-Restarts

WARNING: Load may restart automatically without warning when operating conditions
permit. Disconnect power before servicing the convertor or connected loads.
The factory default allows auto restarts for noncritical faults. Disable restarts by setting DIP
switch 2 to the ON position – see Figure 24.
After non-critical faults clear, the converter will automatically restart after a minimum 60
second delay. The LCD screen displays the auto restart count down. Cycle input power to
abort the restart delay and manually restart the converter. If an Auto Restart Fault repeats
th
10 times, the 11

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.
WARNING! Make sure the input power disconnect switch is in the OFF position
before opening the front cover to the unit. Opening the front cover with the switch in the ON
position exposes the user to the risk of electric shock.
WARNING: Risk of electric shock. Disconnect all incoming sources of power and wait
30 minutes before opening the front cover to perform the following task.

Transformer Mode

Transformer Mode will allow T3 to drop in voltage during heavy startups. To enable
Transformer Mode, follow the steps below:
