for at least 15 minutes. 
1.11  Power-off Procedure 
When the supply is not in use, be sure to turn the power switch on the panel 
to the OFF position to turn off the power. After the power switch is turned to 
the OFF position, the inner fans will still run for approximately 10-15 seconds 
to carry on the inside electric capacitor  discharge process per safety code 
requirement. Once the discharge process is complete, this product will carry 
out the automatic shut-down process. 
1.12  Caution 
D.  Do not connect multiple power supplies in series as it may cause damage 
or malfunction. 
E.  While  in  parallel  connection  mode,  the  output  voltage  of  each  power 
supplies should be set to equal values. If the setting value of each unit is 
not the same, the higher output voltage will feed back to the smaller unit 
and damage its internal components. 
F.  When the AC input voltage is lower than the full-load voltage which is 
100 VAC, the supplies will activate an inner overtemperature protector 
and cut off the output in response to the condition. To ensure that the entire 
test process can be completed smoothly, confirm that the input AC voltage 
is within the specified range.
