nWhen a non-regulated source is used as a front end, make sure

that the voltage fluctuation together with the ripple voltage will not

exceed the input voltage range.

When too much stress is applied on the input/output pins of the

unit, the internal connection may be weakened. As below Fig. 9.1,

avoid applying stress of more than 19.6N (2kgf) on the pins hori-

zontally and more than 39.2N (4kgf) vertically.

The input/output pins are soldered on PCB internally, therefore,

do not pull or bend them with abnormal forces.

When additional stress is expected to be put on the input/output

pins because of vibration or impacts, fix the unit on PCB (using sil-

icone rubber or fixing fittings) to reduce the stress onto the in-

put/output pins.

nDuring cleaning to drying (the condition that cleaning liquid is

soaked into the ink of name plate), do not touch on the surface of

name plate.

nAfter cleaning, dry them enough.
