Configuration menu functions and screens
01: Output Voltage Configuration
LCD
Parameter 3: Output Voltage Value 
Output can be selected from following choices: 
208:  208Vac (** Important Note) 
220: 220Vac 
230: 230Vac 
240:  240Vac 
** IMPORTANT NOTE: If output voltage is set to 208Vac, maximum power output is de-rated 10%. For example for a 10KVA UPS, 
maximum power output will be 9KVA. 
02: Output Frequency
LCD
60 Hz, CVCF mode
50 Hz, Normal mode
ATO
Parameter 2: Output Frequency 
Output can be selected from following choices: 
 50.0Hz: 50.0Hz. 
 60.0Hz: 60.0Hz. 
 ATO: Automatic: Under this mode output frequency is selected according to input 
frequency: 
50Hz if input is (46Hz y 54Hz) and 
60Hz if input is (56Hz y 64Hz). 
ATO mode is factory default value. 
 
Parameter 3: Frequency Mode 
Adjusting parameter 3, can be selected CF Mode which is frequency converter mode 
or NCF in NON converter mode. 
CF: This mode allows fixing a fixed output frequency in parameter 2. 
NCF: This mode allows output frequency was selected according to the input 
meanwhile input frequency is inside allowed range. If input frequency is out of range 
UPS will go to battery mode. 
 
IMPORTANT NOTE ABOUT FREQUENCY CONVERSION FUNCTION "CF":
* When CF function is enable to generate an output with a different frequency value than input, bypass mode will be automatically 
disable. 
* When CF function is activated, maximum power output is de-rated to 60% of standard power output. For example: for 10KVA UPS 
when CF is activated max. output power is 6KVA.
