  NOTE   
When  the  output  voltage  has  DC  voltage,  the  output  terminal  A  is  positive,  and  N  is 
negative. 
 
1.  Confirm that the power switch is in the OFF position and verify that there is 
no dangerous voltage on the connection terminals. 
2.  Remove the output terminals cover of the power system. 
3.  Refer  to  the  wiring  diagram  and  connect  the  Vs+  and  Vs-  with  armored 
twisted-pair cables. Loosen the screws of the output terminals and connect 
the red and black test cables to the output terminals. Re-tighten the screws. 
When maximum current that one test cable can withstand fails to meet the 
rated current, use multiple pieces of red and black test cables. For example, 
the maximum current is 1,200A, then 4 pieces of 360A red and black cables 
are required. 
4.  Thread the red and black test cables through the output terminals cover of
