Cleaning period : The total time of varnishing, ultrasonic wave and

vaper should be within 2 minutes. In case of ul-

trasonic wave cleaning, the ultrasonic should be

less than 15kw/m . During cleaning to drying

(the condition that cleaning liquid is soaked into

the ink of name plate), do not touch on the sur-

face of name plate.

After cleaning, dry them enough.

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.

When 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.

Select the converter that is able to handle the start-up current (Ip).
