Power Supply Precautions for Correct Use
■
Installation

Mounting Methods
The standard mounting methods should
be used to ensure proper heat
dissipation. If other mounting methods
must be used, the ambient temperature
must be lowered or the load rate must
be reduced to prevent temperature
increase inside the Power Supply
caused by poor heat dissipation.
Refer to the information in the table on
the right.
