DIP SWITCH SETTINGS
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 change the DIP switch.

DIP Switch Function Default
2 Disable Auto Restarts OFF
9 & 10
Bypass AUX1 & AUX2 both ON
OFF/OFF
10 Enable VFD Mode note: SW9 must be OFF OFF
AUX Inputs Bypass
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.
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 with some
VFDs to prevent overheating of the VFD due to imbalanced currents induced by the non-
linear nature of the VFD inverter. Set DIP switch 10 to the
ON position to enable VFD
mode.
