5.7.8  DC Setting 
1. There are three related pages, as shown below:   
DC Volt Alarm 
Over:    58.5V 
Low:        45.0V 
Under:  45.0V 
 
 
Amb. Temp Alarm
 
High:        25°C 
Low:          0°C   
 
 
 
Load Shunt     
 
                None 
Shunt Coeff:       
None 
 
 
Use “
” or “
” to select one page or one of the parameters, and “
” or “
” to 
select the parameter value. Press “ENT” to confirm and save. 
2. The value description of the parameters is listed below:   
Table 5-16    Value description of DC settings 
Parameter  
Range 
Default 
Value description   
Over 
(over-voltage) 
58.5V 
The “DC Over Voltage” alarm will be raised when 
the system DC output voltage is higher than the 
value of “Over”   
Low 
(low-voltage) 
45.0V 
The DC low voltage alarm will be raised when the 
system DC output voltage is lower than the value 
of “Low”   
Under 
(under-voltage) 
40V ~ 60V 
45.0V 
The DC under voltage alarm will be raised when 
the system DC output voltage is lower than the 
value of “Under”   
The values of 
these three 
parameters should 
be: Over > Low > 
Under  
High (high 
temperature) 
10°C ~ 
100°C 
40°C 
The high temperature alarm will be raised when 
the detected ambient temperature is higher than 
the value of “High”   
Low (low 
temperature)  
-40°C ~ 
10°C 
-5°C 
The low temperature alarm will be raised when 
the detected ambient temperature is lower than 
the value of “Low”   
The value of 
parameter “High” 
must be higher 
than that of 
parameter “Low”   
Load shunt 
Y, None 
None 
Set according to the system actual situation 
Shunt Coeff   
Dependent on system 
type 
In the system with a load shunt, this parameter can be set only when 
the parameter “Shunt” (as a system type) is set to “Set”.
