Series Operation
Only models with power ratings of 50, 100, 150, 300, or 600-W allow
series operation.
Up to two of the above Power Supplies can be used in series
operation.
Models other than the above Power Supplies cannot be used in
series operation.
If series operation is attempted for other models, the output from one
of the Power Supplies may not come ON when the AC input is
applied. If that occurs and the Power Supplies are left in that state,
internal circuits may be damaged.
Although Power Supplies having different specifications can be
connected in series, the current flowing through the load must not
exceed the smaller rated output current.
With the S82J-05024@@ or S82J-10024@@, if the load is shorted a
reverse voltage may result in the Power Supply causing deterioration
and damage. It is recommended that diodes are connected as
shown in the previous diagram (D

, D

).
Parallel Operation
Only 300- and 600-W models can be in parallel operation. Do not
operate any other models in parallel. The output of the models in
parallel operation is a maximum of 80% of the rated output.
Set the parallel operation selector to PARALLEL if the Units are in
parallel operation and make sure that the thickness and the length of
all wires connected to the load are the same to ensure that the wires
will have no voltage drop differences.
Fan Replacement
The service life of the fan is approximately 50,000 hours (at 25°C).
The service life varies, however, depending on the ambient
temperature or other surrounding environmental conditions such as
dust. As a preventive maintenance measure, replace the fan within
two years if it is used at an ambient temperature of 40
°C.
Fans are available as replacements.
Fan Set:
Fan (above), four M4 x 35 sems screws, instruction sheet, and
packing case
Replace the fan as shown in the following illustration.
