The maximum temperature of the electrolytic capacitor C51 or C52 (VS50E-3 and 5 are C53) must become lower than “Electrolytic capacitor
upper bound temperature” in the above table. Please let air 0.5m

5-3. Mounting Method
Insert the spacer (Max
φ
8.0) of height more than 6mm to lift the unit. Also use all mounting holes for the unit installation. The vibration spec
is that the unit mounted by 6mm spacers.

Consider the heat radiation and safety when the power supply is used in convection cooling. Please take a distance more than 15mm between
the power supply and the peripheral parts. When lay out multiple units, please make sure to place 15mm or more space from each other.
