1.3.2 Storage environment
The storage environment in which the dynamic breaking unit should be stored after purchase differs from the installation
environment. Store the dynamic breaking unit in an environment that satisfies the requirements listed below.

Assuming comparatively short time storage, e.g., during transportation or the like.
*2
Even if the humidity is within the specified requirements, avoid such places where the dynamic breaking unit will be subjected to sudden
changes in temperature that will cause condensation or freezing.
Precautions for temporary storage
(1) Do not leave the dynamic breaking unit directly on the floor.
(2) If the environment does not satisfy the specified requirements listed in Table 1.3-2, wrap the dynamic breaking unit in an
airtight vinyl sheet or the like for storage.
(3) If the dynamic breaking unit is to be stored in a high-humidity environment, put a drying agent (such as silica gel) in the
airtight package described in (2) above.
[ 2 ] Long-term storage
The long-term storage method of the dynamic breaking unit varies largely according to the environment of the storage site.
General storage methods are described below.
(1) The storage site must satisfy the requirements specified for temporary storage.
However, for storage exceeding three months, the ambient temperature range should be within the range from -10 to
30°C. This is to prevent electrolytic capacitors in the dynamic breaking unit from deterioration.
(2) The package must be airtight to protect the dynamic breaking unit from moisture. Add a drying agent inside the package
to maintain the relative humidity inside the package within 70%.
(3) If the dynamic breaking unit has been installed to the equipment or cabinet at construction sites where it may be
subjected to humidity, dust or dirt, then temporarily remove the dynamic breaking unit and store it in the environment
specified in Table 1.3-2.
Precautions for storage over 1 year
If the dynamic breaking unit has not been powered on for a long time, the property of the electrolytic capacitors may
deteriorate. Power the dynamic breaking unit on once a year and keep the dynamic breaking unit powering on for 30 to 60
minutes.
