III. INSTALLATION
A. Location
1. Standard enclosed motors are used where they are exposed to dirt, moisture, and most
outdoor conditions.
2. Severe-duty enclosed motors are used in highly corrosive or excessively moist areas.
B. Mounting
Mount motors securely on a firm, flat base. If necessary, grout in larger motors. Motors
can be mounted per the chart shown. For vertical mounting, check with GE a
representative for recommendations.
X-allowed N/A Not Allowed
C. Alignment
1. Direct Coupling
Align motors accurately. For direct drive, use flexible couplings if possible. For drive
recommendations, consult drive or equipment manufacturers or GE.
Accurate mechanical alignment is essential for successful operation.
For base assembly and motor mounting, the bolts must be carefully tightened to
prevent changes in alignment and possible damage to the equipment. It is
recommended that a washer be used under each nut or bolt head to get a secure hold
on the motor feet. As an alternative, flanged nuts or bolts may be used.
Use bolts that are a minimum Grade 5 or ISO 8.8. See Table 2. The recommended
tightening torques for SAE (Grade 5) bolts, or ISO 8.8 bolts are in Table 3.
Warning
Coupling, belt and chain guards should be installed as needed to protect against accidental
contact with moving parts. Machines accessible to personnel should be further guarded by
screening, guard rails, etc., to prevent them from coming in contact with the equipment.
Failure to observe these precautions may result in injury to personnel.
