Voltage Selector Switch Sw2 (0558007183)

The Voltage Selector Switch is a three position switch designed to alter the configuration of the filter bus
to accommodate 230 VAC or 460 VAC input voltages. This switch is only in the 230/460 VAC selectable
models.
The filter caps are configured in two different ways in the PC1600 230/460 model, dependant upon the
input voltage. The power selector switch SW2 will place the four filter capacitors in either a series configu-
ration or in a parallel pair configuration.
The Voltage Selector switch is a three position switch with a center "Off" position. If this switch is changed
during normal operation, the system will shut down to prevent damage to the unit. The unit will remain inop-
erable until it is shut off and powered back up. If the voltage input is incorrect, the machine will give you a
voltage fault.
