Voltage & Frequency Settings

Unless otherwise specified on the order, the controller voltage and frequency settings are set at the factory to the default values. If a setting must be changed, carefully follow the procedure on the next page. Some settings may require a password (if the controller is set up for one).



			Any indiscriminate change in these settings may affect the normal
		operation of the Automatic Transfer Switch. This change could allow
			the load circuits to remain connected to an inadequate source.
