0
C~40
0
C.
b. Humidity: Relative humidity below 90% RH for totally enclosed type.
c. Elevation: Below 1000 metres.
d. Should the installation be in an industrial zone, it should be free of explosive
gases and liquids.
e. Foundation should be strong so as not to induce vibration.
3.4.2. Ventilation and Space.
a. Installation should be well ventilated.
b. The area should be large enough to facilitate heat dissipation and
maintenance.
3.4.3. Foundation.
Use rigid and solid sole plate or common bed as the foundation.
3.5. MOUNTING.
3.5.1. An adequate motor support (which is the responsibility of others) is very
important. It must have sufficient rigidity to maintain alignment between
the motor and its driven load. Inadequate or improperly designed motor
supporting structures can lead to serious vibration and alignment problems.
3.6. COUPLING & ALIGNMENT.
Two pole motors and motors larger than Frame 315M must not be coupled to
the driven equipment by means other than direct connection.
Please refer to TECO if belt connection is to be used.
