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
