Caution and Matters
8-1
(Please lay the motors carefully in transportation to avoid any serious
damage to the motor body or its electric function because of collision.)
8-2
(Please use and storage motors according to N0.2 item
(Operating Conditions) in specification, or else motor characteristics would
be affected.)
8-3
(Make arrangement to limit the storage period to 6 months
or less. Condensation of atmosphere must be avoided in motor usage or
opening the packaging of the motor.)
8-4 (For proper operation. storage and operating environment must not
contain corrosive gases. For example H2S. SO2. NO2. CL2. etc. In addition
storage environment must not have materials that emit corrosive gases
especially from silicon. cyanic. formalin and phenol group. In the mechanism
or the set.
existence of corrosive gases may cause no rotation in motor.)
8-5 (Please don't stall the shaft for a long time after powering, and
not to touch the weight when motor is rotating.)
8-6 (There should be no sundries
(such as grain, fibre, hair, small tape, glue etc.) in the shaft end play.)
