1.4 Storage Environment

1.4.1 Temporary storage

Store the drive in an environment that satisfies the requirements listed in Table 1.1.
Item
Storage temperature (*1)
Relative humidity
Atmosphere
Atmospheric pressure
*1: The storage temperature applies only to short periods of time, such as during transportation.
Precautions for temporary storage
(1) Do not place the drive directly on the floor.
(2) If the storage environment does not meet the specified requirements, wrap the drive in an airtight vinyl sheet or
similar for storage.
(3) If there is a possibility that the drive will be exposed to high humidity, add a drying agent (such as silica gel) in
the airtight package described in item (2).

1.4.2 Long-term storage

The long-term storage method for the drive varies 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 should be within the range of -10 to
30°C (14 to 86˚F). This is to prevent electrolytic capacitors in the drive from deterioration.
(2) The package must be airtight to protect the drive from moisture. Add a drying agent inside the package to
maintain the relative humidity inside the package at less than 70%.
(3) If the drive has been installed to the equipment or control board at construction sites where it may be subjected
to humidity, dust or dirt, then remove the drive and store it in a suitable environment.
Precautions for storage over 1 year
If the drive has not been powered on for a long time its electrolytic capacitors may deteriorate. Power the drives
on once a year and keep the drives powered on for 30 to 60 minutes. Do not connect the drives to motors or run
the motor.
