RECEIVING
1. Check nameplate data.
2. Check whether any damage has occurred during transportation.
3. After removal of shaft clamp, turn shaft by hand to check that it turns freely.
4. If motor is to be reshipped (aloneorinstalledtoanotherpiece of equipment) the shaftmustagain
be clamped to prevent axial movement.
Note: Remove the bearing clamp before turning the shaft on 284T-449TZ frame motors.
WARNING
THE FOLLOWING SAFETY PRECAUTIONS MUST BE OBSERVED:
1. Electric rotating machinery and high voltage can cause serious or fatal injury if improperly
installed, operated or maintained. Responsible personnel should be familiarized with
NEMA MG-1; Safety Standards for Construction and Guide Selection. Installation and Use of
Electric Motors and Generators; National Electric Code and all local safety requirements.
2. Whenservicing, all power sourcesto themotorand to the accessory devicesshouldbe
de-energized and disconnected and all rotating parts should be at standstill.
3. Liftingmeans, when supplied, are intended for lifting the motor only. When two lifting
devices are supplied with the motor a dual chain must be used.
4. Suitable protection must be used when working near machinery with high noise levels.
5. Safeguard or protective devices must not be by-passed or rendered inoperative.
6. The frame of this machine must be grounded in accordance with the National Electric Code and
applicable local codes.
7. A suitable enclosureshouldbe provided to prevent access to the motorby other than
authorized personnel. Extra caution should be observed around motors that are
automatically or have automatic re-setting relays as they may restart unexpectedly.
8. Shaft key must be fully captive or removed before motor is started.
9. Provide proper safeguards for personnel against possible failureof motor-mounted brake,
particularly on applications involving overhauling loads.
10.Explosion proof motors are constructed to comply with the label service procedure manual, repair
of these motors must be made by TECO-Westinghouse Motor Company or U/L listed service
center in order to maintain U/L listing.
LOCATION
1. Drip-proof motors areintended foruse whereatmosphere is relatively clean, dry, well
ventilated and non-corrosive.
2. Totallyenclosed motors maybeinstalledwhere dirt, moisture, or dustarepresent andinoutdoor
locations.
3. Explosion-proof motors are built for use in hazardous locations as indicated by
Underwriters’ label on the motor.
4. Chemical duty enclosedmotors aredesigned for installation in highcorrosionor excessive
moisture locations.
Note: in all cases, no surrounding structure should obstruct normal flow or
ventilating air through or over the motor.

1. Mount motor securely on a firm, flat base. All ball bearing normal thrust motors up to and
including 256T frame size may be side-wall or ceiling mounted; all others check nearest
TECO-Westinghouse office for mounting recommendations.
2. Align motor accurately, using a flexible couplingif possible.For driverecommendations,
consult with drive or equipment manufacturer, or TECO-Westinghouse.
3. Mounting bolts must be carefully tightened to prevent changes in alignment and possible
damageto the equipment. The recommended tightening torque’s for medium carbon steel bolts,
identified by three radial lines at 120 degrees on the head, are:

POWER SUPPLY & CONNECTIONS
1. Wiring of motor and control, overload protection and groundingshould be in accordance with
National Electrical Code and all local safety requirements.
2. Nameplate voltage and frequency should agree with power supply. Motor will operate
satisfactorily on linevoltage within ±10% of nameplate voltage; or frequency with ±5% and
with a combined variationnot to exceed ±10%. 230-volt motors can be used on 208-volt
networksystems, but with slightly modified performance characteristics as shownon the
nameplate.
3. Dual voltage and single voltage motors can be connected for the desired voltage by
following connection diagram shown on the nameplate or inside of the conduit box.
4. All Explosion Proof motors have Temperature Limiting Devicesin the motorenclosureto
preventexcessive external surface temperature of the motor in accordance with U/L
standards. Terminals of thermal protectors (P1 & P2) should be connected to the motor
control equipment, according to the connection diagram inside of the conduit box.
5. Standard connection diagram for three phase, not thermally protected, dual rotation motors
are shown in diagrams A through E. (Note: To change rotation, Interchange any two line
leads)
Page 8
Page 9
Page 10
*Important: For Part Winding Start, M2 contactor should be closed within two (2) seconds
after M1 contactor is closed.
Only 4 pole and above (e.g., 6P, 8P...) motors are satisfactoryfor Part WindingStart
at low voltage.
START UP
1. Disconnect load and start motor. Check direction of rotation. If rotation must be changed,
ALLOW THE MOTOR TO STOP COMPLETLEY. Interchange any two leads of a three-phase
motor.
2. Connect load. The motor should start quickly and run smoothly. If no, shut power off at once.
Recheck the assembly including all connections before restarting.
3. If excessive vibration is noted, check for loose mountingboltstoo flexible motor support
structure or transmitted vibration from adjacent machinery. Periodic vibration checks should
be made; foundations often settle.
4. Operate under load for short period of time and check operating current against nameplate.
TESTING
If themotor hasbeen in storage for an extensive period or has been subjected to adverse moisture
conditions,it is best to checkthe insulation resistance of thestatorwinding witha megometer.
Depending on the length and conditions of storage it may be necessary to regrease or change
rusted bearings.
If the resistanceis lower than one megohm the windings should be dried in one of the following two
ways:
1. Bakein oven at temperatures not exceeding 194°F untilinsulation resistance becomes
constant.
2. With rotor locked, apply low voltage and gradually increase the current through windings until
temperature measured with a thermometer reaches 194°F.Do not exceed this temperature.

INSPECTION
Inspect motor at regular intervals. Keep motor clean and ventilation openings clear.
LUBRICATION
1. Frame 143T-256T: Double shielded and pre-lubricatedball-bearingmotors without grease
fittings and don’t need re-lubrication, except on MAX-E1®and MAX-E2®products which
have re-greasable features.
2. Frames 280TS, 320-449TZ(TS): Motors having grease fittings and grease discharge
devices at brackets. Motors are shipped with grease for initial running. It is necessary to
re-lubricate anti-friction bearingmotors periodically, depending on size and type of service. See
Table 2 to provide maximum bearing life. Excessive or too frequent lubrication may damage
the motor.

Note:
A. Standard conditions: 8 hours operation per day, normal or light loading, clear and 40°C
ambient conditions.
B. Severe conditions: 24-hour operation per day or light shock loading, vibration or in dirty or
dusty conditions.
C. Extreme conditions: With heavy shock loading or vibration or dusty conditions.
D. For doubleshielded bearings, abovedata (lubrication frequency) means thatthe
bearing must be replaced.
3. Be sure fittings are clean and free from dirt. Using a low-pressure grease gun, pump in the
recommended grease until new grease appears at grease discharge hole.
4. Use the POLYUREA grease unless special grease is specified on the nameplate.
5. If re-lubrication is to be performed with the motor running, stay clear of rotating parts. After
re-greasing, allow the motor to run for ten to thirty minutes.
