Nidec RINDCODE NRX Series, Instruction Manual

4

Perform periodical inspection to check that the aforementioned storage procedures have been taken properly, and that the storing methods 

are correct.

(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.

(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.

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
