PRIME PLUS � 1/1 � 1-3 kVA � ΟNLINE UPS
16: EPO logic setting
Parameter 2: Set up the EPO function control logic.
AO: Active Open (Default). When AO is selected as EPO
logic, it will activate EPO function with Pin 1 and Pin 2 in
open status.
AC: Active Close. When AC is selected as EPO logic, it will
activate EPO function with Pin 1 and Pin 2 in close status.
17: External output isolation transformer connection
Parameter 2: Allow or disallow external output isolation
transformer connection.
ENA: If selected, it’s allowed to connect to an external
output isolation transformer.
DIS: If selected, it’s not allowed to connect to external
output isolation transformer. (Default)
18: Display setting for autonomy time
Parameter 2: Set up the display setting for autonomy time
EAT: If EAT is selected, it will display the remaining
autonomy time. (Default)
RAT: If RAT is selected, it will show accumulated autonomy
time so far.
19: Acceptable input voltage range setting
Parameter 2: Set the acceptable high voltage point and
acceptable low voltage point for input voltage range by
pressing the Down key or Up key.
HLS: Input high voltage point
For 200/208/220/230/240 VAC models:
280/290/300: setting the high voltage point in parameter
2. (Default: 300Vac)
For 100/110/115/120/127 VAC models:
140/145/150: setting the high voltage point in parameter
2. (Default: 150Vac)
LLS: Bypass low voltage point
For 200/208/220/230/240 VAC models:
110/120/130/140/150/160: setting the low voltage
point in parameter 2. (Default: 110Vac)
For 100/110/115/120/127 VAC models:
55/60/65/70/75/80: setting the low voltage point in
parameter 2. (Default: 55Vac)
