Safety standard approved motor
EN Standard (to be considered when exporting motors to Europe)
It is a safety standard applied within the EU's borders, most part of which is based on the IEC standard. In
Europe, the power supply voltage is as high as single-phase 230 V and 3-phase 400 V and it is therefore
necessary to give consideration to electric shock in particular (Low Voltage Directive). In addition, because the
mechanical safety (Machinery Directive) is considered, there is a recognition that it is dangerous for a motor to
move suddenly as a result of automatic resetting of the protector etc. It is therefore required that, after the
occurrence of an abnormal condition activating the protector, the machine can be started only when manual
resetting is made by the operator. It is necessary to put a CE mark on products that have passed the test of the
EN standard and are to be exported and to show clearly their safety level. (The product level is specified in the
instruction manual. In Europe, when a (safety) self-declaration is required by a user, it should be submitted to the
user.) In the case of a motor with speed controller, it is necessary to show clearly the level of malfunction
(including malfunction of the motor and damage to other equipment) due to electromagnetic interference. (Check
the level individually.) This level is evaluated based on the motor and controller alone. Because electromagnetic
interference varies significantly depending on the wiring for incorporation into equipment, this level should be
regarded as a reference value and a final determination should be made after incorporation into equipment.

GB Standard (to be considered when exporting motors to China)
In the People's Republic of China, China Compulsory Certification (CCC) is applied to products affecting health
and safety of people, life and safety of animals and plants, environmental protection and public safety. Our motors
are subject to CCC (excluding some motors) and a CCC certification mark is put on the main body of a certified
motor.
