8. Storage
■
Do not store the inverter in locations that are exposed to extreme
temperature/humidity variations
Extreme storage temperatures and condensation may cause performance degradation
and/or equipment failure.
Storage environment
：
Ambient temperature -35
～
50
℃
Relative humidity less than 95% (No condensation)
■
The inverter must be stored indoors
The inverter shall not be stored outdoors and exposed to rain, wind and/or condensation
(produced by temperature variation) to prevent performance degradation and/or failure.
This applies even considering that the inverter is outdoor rated
■
Do not store the inverter in locations with considerable amount of fine particles
that may contain iron and/or organic compounds
It may cause insulation failure, contact failure in circuit breakers and switches,
performance degradation and/or failure.
■
Do not store the inverter in places where vibrations(
※
1) or mechanical
shocks(
※
2) may occur
Vibrations or shocks may cause performance degradation and/or failure.

Refer to “Inverter installation environment” in section 5.1 for details
■
Do not store the inverter in places exposed to air containing salts, corrosive
gases (
※
3) and/or vapor containing water or oil
If stored in a place where one of the above elements is present, contact failure in circuit
breakers and switches may occur, and may lead to performance degradation and/ or
failure.

：
Refer to “Inverter installation environment” in section 5.1 for details
■
When storing the inverter before/after installation for a prolonged period of time,
protect the inverter from humidity
In case the inverter is not protected from humidity, rust may appear in components and
may cause performance degradation and/or failure. Repair work would be required.
Take one of the following protective measures against humidity
(1) Place desiccant inside the cabinet (Refer to the table below).
(2) Reduce the humidity inside the cabinet using a space heater or a similar device.
(3) Reduce the humidity inside the cabinet by periodically operating the inverter under
no-load conditions.
