230V

2. INSTALLATION 

 

1)

 

Before  installation,  please  make  sure  the  AC  input  voltage  is 

correct. 

The AC input voltage of 72-7675 is either 115V or 230V, which 

can be selected. The select switch is located on the rear panel. 

 

2)

 

Before connecting the power cord to the suitable outlet, please 

make  sure  all  the  72-7675’s  breakers  are  turned  off.  It  will 

avoid the unnecessary accident or damage to the unit. 

3)  Plug the input power cord to the suitable outlet.   

4)

 

Please make sure the input tolerance is within 

±

10% of rated 

voltage (see figure 1).
