6. Handling explanation 

 

Please handle it correctly after paying attention to the following points. 

(1) When applying the auxiliary power supply and input, check that the voltage and input signal of the  

auxiliary power supply conform to the specifications of this product. 

(2)Make sure that the external wiring is connected to the specified terminal position (listed on the  

nameplate). 

(3)Please use the output load within the output load range indicated on the name plate. 

If the output load range is exceeded, not only will the output error, but the product will be  
burdened.  Especially for voltage output products, do not short-circuit the output. 
This product will not be damaged even if the output terminal is left open in the current output  
specifications.  However, a voltage of about 15V is generated. 

(4)The output adjustment range is BIAS:±5% of the output span, MAX.:±5% of the output span. 

Use only when adjustment is required for matching with connected devices. 

(5) The output value when only the auxiliary power supply is applied or when the auxiliary power supply  

and BUS side input and the auxiliary power supply and START side input are applied will be the  
specified output value. 

Specification code
