Motor Size, Compliance, & Installation
EQP Global IEC Series Low-Voltage 50/60 Hz Metric Motor
All dimensions are in millimeters (inches).
Divide the millimeter value by 25.4 to convert
to inches.
Any motor operated using an Adjustable
Speed Drive is subject to potential premature
bearing failures due to the increased shaft
currents. This condition is caused by inherent
common mode voltages that occur when
operating using a sinusoidal 3-phase power
source.
All motors are at risk for shaft currents. The
completed installation should be thoroughly
reevaluated for all applications. The use of
insulated bearings or shaft grounding devices
is recommended if shaft currents are present.
For drive recommendations and/or support,
consult the
TIC Customer Support
The user is responsible for protecting the
couplings and driven equipment from shaft
currents from the motor. Insulated couplings
are recommended. Shaft grounding devices
provide additional protection, but cannot be
used in hazardous areas because of arcing.
Match the nameplate rating of the motor,
connection diagram, and lead numbers with
the appropriate category for the applicable
connection requirement. TIC special-built or
special-rated motors may follow different
connections.
Contact the
TIC Customer Support Center
more information is required — have the
nameplate model number and serial number of
the motor for connection information.

Motor Installation and
Coupling
Motor Installation
Installation of the motor includes preparing the
mounting location, installing the bedplate, grouting,
and coupling the motor to the load.
Each of these requirements are discussed in this
section.
Location
Unless otherwise specified, the ambient operating
temperature is -15° to 40° C (5° to 104° F).
Install the motor securely on a firm and flat base.
Ensure that the installation is in a well-ventilated
Center.
location that is easily accessible for cleaning,
inspection, and maintenance — this includes being
away from walls and other obstructions to permit a
free passage of air. Ensure that there are no
obstructions to the operation of the motor.
Avoid installation locations that would allow
exposure to coal or mill dust, leaky pipes, steam/
moisture, acids, or the fumes thereof, or any other
harmful substances.
Do not install the motor in an area where flammable
gases or combustible material may be present, or
around any hazardous processes, unless designed
for such an application.
if
Drip Proof motors are designed for indoor
installations in a well ventilated area where the
atmosphere is reasonably free of dirt, moisture, and
corrosion. Contact TIC for any required
modifications.
Totally-enclosed motors may be installed where dirt,
moisture (not running water), and corrosion are
present. Outdoor applications are acceptable;
additional application-specific measures may be
required. Contact TIC for any required
modifications.
