BEFORE USING THE POWER SUPPLY UNIT 

  Pay attention to all warnings and cautions before using the unit. Incorrect usage could lead to an electrical 

shock, damage to the unit or a fire hazard. 

   

WARNING and CAUTION 

 

Do not modify. 

 

Do not touch the internal components, they may have high voltage or high temperature. You may get       
electrical shock or burned. 

 

When the unit is operating, keep your hands and face away from it as you may be injured by flying debris in 
the event of a fault. 

 

This power supply is designed for use within an end product. Stick the WARNING label for users on the   
system equipment and notify in the system instruction manual. 

 

Never operate the unit under over current or short-circuit conditions for more than 30 seconds or outside its 
specified Input Voltage Range, which could result in damage but there is no possibility of fire or burning. 

 

Confirm connections to input/output terminals are correct as indicated in the instruction manual. 

 

This power supply has a possibility for hazardous voltage to appear at output terminal depending on the type 
of failure. The outputs of these products must be earthed in the end equipment to maintain SELV. 

      If the outputs are not earthed, they must be considered hazardous and must not be made user accessible.       
       

Note: CE MARKING

 

 

CE marking, when applied to the GWS series products, indicates compliance with the Low Voltage Directive 

(2014/35/EU) in that it complies with EN60950-1 2
