ASSEMBLY
INSTALLATION
Mounting
Foot mounted:
Foot mounted motors should be mounted to a rigid foundation to prevent excessive
vibration. Shims may be used if the location is uneven.
Flange mounted:
Flange mounted motors should be properly seated and aligned. If improper rotation
direction is detrimental to the load, check the rotation or ‘bump’ the motor prior to coupling the load to
the motor shaft.
V-belt drive:
Mount the sheave pulley close to the motor housing. Allow clearance for end-to-end
movement of the motor shaft. Do not over-tighten belts as this may cause premature bearing failure or
shaft breakage.
Direct coupled:
Direct coupled motors should be carefully aligned and the shaft should rotate freely
without binding or drag.
Build a Guard
WARNING! Guards must be installed to form a safe and uncompromised perimeter around rotating
parts such as couplings, pulleys, external fans and unused shaft extensions.
After motor installation is complete, a guard of suitable dimensions must be constructed and installed
around the motor. This guard must prevent personnel from coming in contact with any moving parts
of the motor or drive assembly, but must allow sufficient cooling air to pass over the motor. If a motor
mounted brake is installed, provide proper safeguards for personnel in case of brake failure.
All parts should be permanently guarded to prevent accidental contact by personnel. Accidental contact
with body parts or clothing can cause serious or fatal injury. When this motor is installed according to
these instructions, it complies with the EEC Machinery Directive. Electromagnetic Compatibility (EMC)
requirements for CE compliance are met when the incoming power is purely sinusoidal.
ELECTRICAL INSTALLATION
Grounding the Motor
Ground the motor according to CE and local codes.
Consult the Canadian Electrical Code (CE) for information on grounding of motors and generators and
general information on grounding. In making the ground connection, the installer should make certain
that there is a solid and permanent metallic connection between the ground point, the motor or generator
terminal housing and the motor or generator frame.
