Instruction Manual
BEFORE USING THE POWER SUPPLY UNIT
Pay attention to all warnings and cautions before using the unit. Incorrect usage may 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; it may have high voltage or high temperature. You may get electrical
shock or burn.
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.
Hazardous voltage may appear at output terminals 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 LS series products, indicates compliance with the Low Voltage Directive
(2006/95/EC) in that it complies with EN60950-1 2nd edition.
