12 13InstallationInstall the brushless motor and brushless amplifier properly for preventing failureand accident.Transport• Do not carry the motor by holding the cable or the shaft.• Do not drop or topple products.Storage• Keep the unit indoors in a clean and dry place free from vibration with little change oftemperature.• In keeping a gear head alone, direct the output shaft down.(Otherwise, grease leakage may occur.)Location• Location gives great influence upon the life of brushless motor and brushless amplifier,therefore choose a place in conformance with the conditions below:(1) Where vibration and shock do not participate.(2) Place where foreign matter such as dust, metal powder, oil mist etc is not applied.(3) Places where liquid, such as water, oil, grinding fluid etc is not applied.(4) A place away from inflammable materials.(5) Places where there is no influence of hydrogen sulfide, zinc acid, chlorine, ammonia,sulfur, chloride gas, sulfurizing gas, corrosive gas such as acid, alkali, salt andflammable gas.(6) A place away from the heating element.(7) Install on incombustible materials such as metal.(8) Places where rainwater or direct sunlight does not fall.(9) Well ventilated, there are no obstacles to block ventilation around.(10) Easy to check and clean.Caution in installing gear headInstall a device that will ensure safety operation of the system even if the followingfailures should occur on the life end of gear head: idling by damaged teeth, lockingby bite, grease leakage, and the like.• As for application such as on a lifter or the like device, install a device for preventing dropby damaged teeth.• As for application such as opening and closing of door, install a release device againstlocking by gear biting.• As for food or textile equipment, install an oil pan for measures against grease leakage.• Do not install an encoder, sensor, contact, etc., in the proximity of gear head. Orotherwise, protect such devices against grease leakage.• In order to prevent unexpected accident, be sure to perform daily check.Environmental conditionItem ConditionAmbienttemperatureBrushless motor –10 ℃ to 40 ℃ (free from freezing) *1Brushless amplifier 0 ℃ to 40 ℃ (free from freezing) *1Digital key pad(Option) 0 ℃ to 50 ℃ (free from freezing) *1Ambient humidity 20 % to 85 %RH (free from condensation)Storage temperature –20 ℃ to 65 ℃ *2ProtectionstructureBrushless motorIP65(Excluding shaft pass-through section and lead wire connector)• This motor meets test requirements specified in ENstandards (EN60529 and EN60034-5). This motorcannot be used for an application that requires longterm waterproof performance, such as the case wherethe motor is always washed with water.Brushless amplifierEquivalent to IP20Digital key pad(Option)Vibration Not greater than 5.9 m/s 2 (10 Hz to 60 Hz)Altitude Not greater than 1000 m*1 Ambient temperature is measured at a distance of 50 mm from the product.*2 Maximum temperature guarantee: 80 ℃ for 72 hours without condensation.Installation of brushless motor• Oil and water protection(1) Direct down the lead of cable as far as possible.(2) Avoid use in such an environment where the motor is always exposed to oil and water.(3) Avoid use with cable immersed in oil or water.• Stress to cable(1) Make sure that stress is not applied to the lead or connection of cable due to bendingor dead weight.(2) In installation where the motor moves, fix the cable of motor, and house the extensioncable connected to it in the cable bear to reduce stress by bending as small aspossible.(3) Allow the bending radius of cable as large as possible.
