Storing Precautions - Nidec RINDCODE NRX Series Instruction Manual

If you do not plan to use the product immediately after purchase, store it under the following precautions.
To store temporarily
(1) Store the product in a clean and dry place.
(2) If you store the product outdoors or in a humid place, put it in a box, seal the box, and cover with plastic sheets.
(3) When storing, attach a red rubber stopper into the air release plug, or set a plug stopper to prevent humidity from entering the product.
To store for a long period of time
1) When storing the product in outdoor areas subject to a lot of rain and/or humidity after installing on the site
(1) Cover the whole product with a water-proof sheet, and fix the sheet securely to prevent it from coming off due to strong wind, as well as
to avoid entering rain and/or dust from clearance gap.
(2) If moisture is expected to evaporate from the ground, put the water-proof sheet underneath to prevent exposure to humidity from the
evaporation, filling inside the sheet.
(3) When storing, attach a red rubber plug into the air release plug, or set a plug stopper to prevent humidity from entering the product.
(4) Set the cover on the motor terminal box, and seal the lead wire openings to avoid humidity from entering through the terminal box to the
inside of the motor.
2) When storing the product indoors
When there is less humidity, cover the product with a plastic bag, etc., and follow the procedures described in (3) and (4) above.
3) When storing the product for a long period of time, over a year, special rust-proofing specifications are required in addition to the above
procedures.
4) Rust-proofing intervals and procedures

Note : Only when the export rust-proofing specifications or instructions are given, rust-proofing oil is applied to the input/output shafts even in less than one year.
Inspection during storage
Perform periodical inspection to check that the aforementioned storage procedures have been taken properly, and that the storing methods
are correct.
Inspection before resuming operation
(1) Return the product to normal conditions from those taken for storage (such as for the amount of special oil).
(2) Since bearings may partially run out of grease resulting from the grease hardening during long-term storage, be sure to turn the motor
shaft by hand from the fan side before operation, and check that there are no problems.
(3) Since exposed parts of rubber and/or resin parts in the oil seal, O-ring, and oil gauge, etc., may become deteriorated due to environmental
influences, such as temperature, humidity, and/or ultraviolet rays, check those parts before resuming operation. If any deterioration is
found, replace with new ones.
