1.HS1,HS2 cannot be shorted.
2.HS1 must have safety isolation distance
with system case.
※Note : 1. The FAN SUPPLY is designed to serve as the source of the additive external fan for the cooling of the power supply, enabling the full load delivery and assuring the best
life span of the product. Please do not use this FAN SUPPLY to drive other devices.
2.The PCB type(Blank type)model delivers EMI Class B for both conducted emission and radiated emission for the power supply, when configured into either Class Ⅰ(with FG)
or Class Ⅱ (without FG) system.
3.The Enclosed type(-C type) model is not suitable for the configuration within a Class Ⅱ (without FG) system but is suggested to used within a Class Ⅰ(with FG) system.
