３. Notes on mounting and handling
● The connection diagrams in these handling instructions
represent the standard connection methods for this prod-
uct. Consult us for use with other connection methods.
● When a choke coil is to be connected between the input
power supply and the No.2 terminal, it should be of 4.7µH
or lower Otherwise, maximum ripple voltage may increase.
● If the ripple voltage of the input power supply is high, or
the ripple returned to input from the converter should be re-
duced, connect a capacitor with the appropriate capacity.
● For proper start-up of the converter, the start-up time of
the input voltage should be 40ms or less. The time after
the input voltage becomes 0.5V until it reaches the speci-
fied input voltage range, should be 40ms or less.
● Parallel operation of outputs for enhancing the output
current of the converter is not applicable.
● Series connection is not applicable for this product.
● Input fuse is not installed in this product.
● Do not use this product in an overload condition. Doing
so can cause failure.
● Cleaning is not applicable for this product.
● Use low-residue or non-cleaning flux.
● Notes on storage
Keep this product indoors with little temperature/humid-
ity change and away from direct sunlight. Note that if
this product is kept in a hot and humid condition or in a
condition with drastic temperature changes, it can cause
condensation, performance deterioration, or solderability
deterioration.
