In order to use the Megatorque Motor System properly,
observe the following notes.
1. Matters to be attended to use the Driver Unit of the Megatorque Motor System
1 Temperature
l
Keep the ambient temperature of the Driver Unit within 0 to 50°C. You cannot put the Driver Unit in an
atmosphere over 50°C. Keep a clearance of 100 mm in upper and lower side of the Driver Unit when it is
installed in the enclosure. If heat is build up on upper side of the Driver Unit, provide the ventilation openings
on the top of it or equip an air cool unit to take the heat out of the Driver Unit.
(Measures against contamination are required for the ventilation openings.)
2 Protection against contamination and water
l
Put the Driver Unit in an enclosure of which protection code is IP54 or better. Protect the Driver Unit from
oil-mist, cutting oil, metal chips and paint fume etc. Otherwise it may result in failure of electric circuits of the
Driver Unit.
(IP code is in IEC standard. This is to specify the protection level of enclosures from solid contamination and
water.)
3 Wiring / Ground
l
Refer to User's Manual for proper wiring.
l
Take appropriate measures not to contaminate the Driver Unit when wiring or installing it.
4 Storing
l

◊
Simple waterproof Motor (RW series)
The Motor is not treated for complete waterproofing. Confirm what part is not waterproof with the
catalog, then take appropriate measures to these parts against water if necessary. To use the
Motor for a long time, check its failure in insulation through the puncture test which shall be
conducted approximately once in every half of a year. Do not use the Motor without taking
measures against water and oil.
◊
