Table 1. Configuration Mode Parameters

Parameter	LCD Message	Description	Default Settings
Output Voltage Setting	O/P V Setting	To change the output voltage
		• Select 208, 220, 230, or 240V for 240V models.	For 240V models:
		You are prompted to save this setting.	O/P V= 230V
Input Voltage Tolerance	I/P Bypass Set	Select the input voltage tolerance range before the UPS	I/P Tol=+10%/-15%
		goes to Battery mode: ±10%, +10%/-15%, or +15%/-20%.
		You are prompted to save this setting.
Input Frequency	I/P F Setting	The factory-default is 50 or 60 Hz, ±5%. Select ±2% for	Freq Tol.=+/-15%
		a narrower frequency range. Select ±7% for a wider
		frequency range.
		You are prompted to save this setting.
High-Efficiency Mode	HE Mode Setting	Select whether High-Efficiency mode is On or Off. If	HE Mode Off
		enabled, you must also select the input voltage range:
		±10% or ±15%.
		While operating in High-Efficiency mode, the UPS
		transfers to utility power when: 1) the input voltage is
		outside ±10% or ±15% from nominal; 2) the input
		frequency is greater than ±3%; or 3) the input line is
		not available.
		You are prompted to save this setting. If the setting is
		not allowed, the LCD shows “I/P out limit” which means
		the input voltage or frequency is not suitable.
Free Run Mode	Free Run Mode	Select whether Free Run mode is On or Off. If enabled,	Free Run On
		you must also select Bypass Disable or Bypass Enable.	(Bypass Disable)
		This selection defines how your UPS runs when the input
		frequency (from the utility) is outside the selected frequency
		tolerance (set via the I/P F Setting, above), but is inside the
		maximum frequency limits the UPS can accept before

switching to Battery mode.

For example: If your 50 Hz UPS is set to the factory default window of ±5% before the UPS starts regulating the frequency.

•The output frequency tracks the input frequency exactly from 47.5 to 52.5 Hz.

•If input frequency is between 45 and 65 Hz, the output frequency is regulated by the UPS to exactly 50 Hz (±0.5 Hz). You are prompted to save this setting.

Alarm Silence	Alarm Silence	Select whether Silence is On or Off. If enabled, the UPS	Silence Off
		silences the alarm for an existing fault. If the UPS status
		changes, the alarm beeps, overriding the previous alarm
		silencing. The alarm does not silence if there is a low
		battery condition.
