Assembling and Installation Method

Installation method

¡

This power supply is manufactured by SMD technology.The stress to P.C.B like twisting or bending causes the defect of the unit, so han-

dle the unit with care.

¡

The mounting screw should be M3. The hatched area shows the allowance of metal parts for mounting.

¡

If metallic fittings are used on the component side of the board,ensure there is no contact with surface mounted components.

¡

This product uses SMD technology.Please avoid the PCB installation method which includes the twisting stress or the bending stress.

*

Recommendation to electrically connect FG to metal chassis for reducing noise.

¿

LMA100F, LMA150F

¿

LMA240F

¡

In case of metal chassis, keep the distance between d1 & d2 for

to insulate between lead of component and metal chassis, use the

spacer of 8mm or more between d1. If it is less than d1 & d2, in-

sert the insulation sheet between power supply and metal chassis.

¡

There is a possibility that it is not possible to cool enough when

the power supply is used by the sealing up space as showing in

right figure.Please use it after confi rming the temperature of point

A and point B of Instruction Manual 3.

¡

(F) mounting is not possible when unit is with case cover, but if

need to operate unit by (F) positioning with case cover, tempera-

ture / load derating is necessary. For more details, please contact

our sales or engineering departments.
