Precautions for Use
2
(12) Cautions for static electricity
Significant volume of static electricity may build up on the human body in extremely dry conditions.
Prior to touching the JW30H, discharge the static electricity by touching grounded metals.
(13) Cleaning
Use the soft cloths for cleaning. Volatile solvents (alcohol, paint thinner, freon etc.) and wet rags may
cause deformation or change of color.
(14) Storage
Keep the JW30H in cool and dry conditions as it equipped with a battery for memory backup.
High ambient temperature may shorten its battery life.
Do not put other objects on the JW30H.
(15) Short circuit protection
If the load connected to the output terminal shorts circuits, the output device or the printed circuit
board may burn. Insert a protective fuse in the output lines.
We recommend that you install protective fuses in each line, even if the external devices have fuses
for each common unit. These common line fuses are to protect the device against burnout caused by
overload, and do not protect against overcurrent of output element and load.
Precautions when using a rated voltage power
source
When you use a power supply for loads that have a
current limiting circuit, provide fuses that match the
load rating of each output module. If the load is
shorted, and the current limiting circuit functions, the
short-circuit current will flow at current level lower than
needed to blow the fuse.
(16) Insulation transformer
Choose isolation transformer with a capacity 20% or more higher than the rated load. When a
transformer of the same capacity as that of the rated load is used, the primary input voltage might
exceed the rated transformer capacity.
* Maximum load capacity when one
power supply module is used.
(17) Max. No. of I/O points
Each control module has a maximum number of input and output points, but the number of relay
points affecting the maximum number of input and output points varies with the type of the module. It
must be noted that it is different from the number of relay assignments.
