INSTALLATIONS
•Mounting the power supply at the four corners with metal spac- ers (2 corners for 10W models).
•Maintain a min. 4mm clearance distance in order to satisfy insu- lation and high voltage safety requirements.
•Lay an insulating sheet under the power supply in case a min. 8mm installation space cannot be secured between the PC board and the housing.
•Provide a min. 4mm distance between heat sink or component surface and surrounding objects in order to cause a thermal con- vection.
•Since components are mounted on the back (solder) side of the product, sufficient care should be taken when handling the power supply to protect the PC board from shock, vibration, tor- sion, etc. which can result in damage caused by cracked chip components.

The shaded portion indicates a side in which an output connector is arranged.
There are installation directions (B) to (F) as shown below in addi- tion to the standard installation direction (A) for mounting the power supply on an apparatus. The installation (B), however, is inhibited because it will cause heat to be trapped inside the power supply.
Derating of the output voltage and the ambient temperature for the installation directions (C) to (F) are not the same as for the direc- tion (A). Please consult us if you need.
• All specifications are subject to change without notice.
