2)Verticalmounting 
•Usethemotorwithoilseal(make-to-orderincaseofmotor750Worless)when
mountingthemotorwithgearreducertopreventthereduceroil/greasefromenter-
ingtothemotor.
3)Forthedimensionsandmassoftheproduct,whicharenecessarydesigndataof
themountingsection,refertothedimensionaloutlinedrawingontheOperatingIn-
structions(Overall)ortheDeliverySpecication.
Oil/Water Protection
1)Don'tsubmergethemotorcabletowateroroil.
2)Installthemotorwiththecableoutletfacingdown-
ward.
3)Avoidaplacewherethemotorisalwayssubject-
edtooilorwater.
4)Usethemotorwithanoilsealwhenusedwiththe
gearreducer,sothattheoilmaynotentertothemotorthroughshaft.
Stress to Cables
1)Avoidastressapplicationtothecableoutletandconnectingportionbybendingor
self-weight.
2)Especiallyinanapplicationwherethemotoritselftravels,xtheattachedcableand
containtheextensionjunctioncableintothebearer sothatthestressbybending
canbeminimized.
3)Take the cable bending radius as large as possible. (When you use our optional
cable,MinimumR20mm)
Permissible Load to Output Shaft
1)Designthemechanicalsystemsothattheappliedradialloadand/orthrustloadto
the motor shaft at installation and at normal operation can meet  the permissible
valuespeciedtoeachmodel.
2)Payanextra attention whenyouuse arigidcoupling. (Excess bendingloadmay
damagetheshaftordeterioratethebearinglife.)
3)
Useaexiblecouplingwithhighstiffnessdesignedexclusivelyforservoapplicationinorder
tomakearadialthrustcausedbymicromisalignmentsmallerthanthepermissiblevalue.
Notes on Installation
1)Donotapplydirectimpacttotheshaftbyhammer
whileattaching/detachingacouplingtoandfrom
themotorshaft. 
 (Orit maydamagetheencoder mountedonthe
othersideoftheshaft.) 
2)Make a full alignment. (incomplete alignment may
causevibrationanddamagethebearing.)
3)
Ifthe motorshaft isnotelectricallygrounded,it maycause electrolyticcorrosionto
thebearingdependingontheconditionofthemachineanditsmountingenvironment,
andmayresultinthebearingnoise.Checkandvericationbycustomerisrequired.

Motor
Install the motor properly to avoid a breakdown or an accident.
Installation Place
Since the conditions of location affect a lot to the motor life, select a place
which meets the conditions below.
1)Indoors,wheretheproductsarenotsubjectedtorainordirectsunbeam.Theprod-
uctsarenotwaterproof.
2)Wheretheproductsarenotsubjectedtocorrosiveatmospheressuchashydrogen
sulde,sulfurousacid,chlorine,ammonia,sulfur,chloricgas,sulfuricgas,acid,al-
kalineandsaltandsoon,andarefreefromsplashofinammablegas.
3)Wherethemotorisfreefromgrindingoil,oilmist,ironpowderorchips.
4)Well-ventilatedandhumidanddust-freeplace,farapartfromtheheatsourcesuch
asafurnace.
5)Easy-to-accessplaceforinspectionandcleaning
6)Vibration-freeplace.
7)
Avoidenclosedplace.Motormaygetshotinthoseenclosureandshortenthemotorlife.
