r.1.

Use the lugs or eye bolts provided to lift the m

otor. Never attem

pt to lift the motor and additional

equipment connected to the m

otor by this method. T

he lugs or eye bolts provided are designed to liftonly the m

otor. Never lift the m

otor by the motor shaft or the hood of a W

PII m

otor.2.

To avoid condensation inside the motor, do not unpack until the m

otor has reached room tem

perature.(R

oom tem

perature is the temperature of the room

in which it w

ill be installed). T

he packing provides insulation from tem

perature changes during transportation.3.

When lifting a W

PII (W

eather Proof Type 2) m

otor, do not lift the motor by inserting lifting lugs into

holes on top of the cooling hood. These lugs are to be used for hood rem

oval only. A

spreader bar should be used to lift the motor by the cast lifting lugs located on the m

otor frame.

4.If the m

otor must be m

ounted to a plate with the driven equipm

ent such as pump, com

pressor etc., it m

ay not be possible to lift the motor alone. F

or this case, the assembly should be lifted by a sling

around the mounting base. T

he entire assembly can be lifted as an assem

bly for installation.D

o not lift the assembly using the m

otor lugs or eye bolts provided. Lugs or eye bolts are designed tolift m

otor only. If the load is unbalanced (as with couplings or additional attachm

ents) additional slingsor other m

eans must be used to prevent tipping. In any event, the load m

ust be secure before lifting.If the load is unbalanced (as w

ith couplings or additional attachments) additional slings or other

means m

ust be used to prevent tipping. In any event, the load must be secure before lifting.

Sto

rage

Storage requirem

ents for motors and generators that w

ill not be placed in service for at least six months

from date of shipm

ent.Im

proper motor storage w

ill result in seriously reduced reliability and failure. An electric m

otor that doesnot experience regular usage w

hile being exposed to normally hum

id atmospheric conditions is likely to

develop rust in the bearings or rust particles from surrounding surfaces m

ay contaminate the bearings.

The electrical insulation m

ay absorb an excessive amount of m

oisture leading to the motor w

indingfailure.A

wooden crate “shell” should be constructed to secure the m

otor during storage. This is sim

ilar to anexport box but the sides &

top must be secured to the w

ooden base with lag bolts (not nailed as export

boxes are) to allow opening and reclosing m

any times w

ithout damage to the “shell”.

Minim

um resistance of m

otor winding insulation is 5 M

eg ohms or the calculated m

inimum

, which ever is

greater. Minim

um resistance is calculated as follow

s: Rm

= kV + 1

where:

(Rm

is minim

um resistance to ground in M

eg−O

hms and

kV is rated nam

eplate voltage defined as Kilo−

Volts.)

Exam

ple:For a 480V

AC

rated motor R

m =

1.48 meg−

ohms (use 5 M

Ω).

For a 4160V

AC

rated motor R

m =

5.16 meg−

Som

e motors have a shipping brace attached to the shaft to prevent dam

age during transportation.T

he shipping brace, if provided, must be rem

oved and stored for future use. The brace m

ust bereinstalled to hold the shaft firm

ly in place against the bearing before the motor is m

oved.2.

Store in a clean, dry, protected w

arehouse where control is m

aintained as follows:

a.S

hock or vibration must not exceed 2 m

ils maxim

um at 60 hertz, to prevent the bearings from

brinelling. If shock or vibration exceeds this limit vibration isolation pads m

ust be used.b.

Storage tem

peratures of 10°C (50°F

) to 49°C (120°F

) must be m

aintained.c.

Relative hum

idity must not exceed 60%

.d.

Motor space heaters (w

hen present) are to be connected and energized whenever there is a

possibility that the storage ambient conditions w

ill reach the dew point. S

pace heaters are optional.N

ote: Rem

ove motor from

containers when heaters are energized, reprotect if necessary.

3.M

easure and record the resistance of the winding insulation (dielectric w

ithstand) every 30 days ofstorage.a.

If motor insulation resistance decreases below

the minim

um resistance, contact your B

aldorD

istrict office.b.

Place new

desiccant inside the vapor bag and re−seal by taping it closed.

c.If a zipper−

closing type bag is used instead of the heat−sealed type bag, zip the bag closed

instead of taping it. Be sure to place new

desiccant inside bag after each monthly inspection.

d.P

lace the shell over the motor and secure w

ith lag bolts.4.

Where m

otors are mounted to m

achinery, the mounting m

ust be such that the drains and breathersare fully operable and are at the low

WARNING

:Guards m

ust be installed for rotating parts such as couplings, pulleys, external fans, and unused shaftextensions, should be perm

anently guarded to prevent accidental contact by personnel. Accidentalcontact w

ith body parts or clothing can cause serious or fatal injury.

INSPECTION

Before connecting the motor to an electrical supply, inspect

for any damage resulting from

shipment. Turn the shaft by

hand to ensure free rotation. Motor leads m

ust be isolatedbefore the shaft w

ill turn freely on permanent m

agnet motors.

DRAIN PLUGS

Condensation drain plugs are provided at four points on

each endplate for various motor m

ounting configurations.For W

ashdown and totally enclosed, fan cooled or

non-ventilated motors, the plugs in the low

est portion of theends shields should be rem

oved for operation (unless them

otor has special stainless steel drains). All drains arelocated in the low

est portion of the ends shields.M

OUNTING

Mount the m

otor on a foundation sufficiently rigid to preventexcessive vibration. G

rease lubricated ball bearing motors

may be m

ounted with the feet at any angle. After careful

alignment, bolt m

otor securely in place. Use shim

to fill anyunevenness in the foundation. M

otor feet should sit solidlyon the foundation before m

ounting bolts are tightened.IP (Ingress Protection)IP designations include tw

o numerals, the first characteristic

numeral is for ingress solid bodies and from

dust.The second for ingress protection from

liquid - water.

Motors m

arked less than IP23 require additional protectionfrom

water.

GUARDING

After motor installation is com

plete, a guard of suitabledim

ensions must be constructed and installed around the

motor/gearm

otor. This guard must prevent personnel from

coming in contact w

ith any moving parts of the m

otor or driveassem

bly but must allow

sufficient cooling air to pass overthe m

otor.If a m

otor mounted brake is installed, provide proper

safeguards for personnel in case of brake failure.Brush inspection plates and electrical connection coverplates or lids, m

ust be installed before operating the motor.

STARTINGBefore starting m

otor remove all unused shaft keys and

loose rotating parts to prevent them from

flying off. C

heck direction of rotation before coupling motor to load.

The motor should start quickly and run sm

oothly and with

little noise. If the motor should fail to start the load m

ay betoo great for the m

otor, the voltage is low or the m

otor hasbeen m

iswired. In any case im

mediately shut m

otor off andinvestigate the cause.

ROTATIO

NTo reverse the direction of rotation, disconnect and lockoutpow

er and interchange any two of the three AC

power leads

for three phase motors. For tw

o-phase four wire, disconnect

and lockout power and interchange the AC

line leads on anyone phase. For tw

o phase three wire, disconnect and lockout

power and interchange phase one and phase tw

o AC line

leads.

Maintenance Procedures

WARNING

:Do not touch electrical connections beforeyou first ensure that pow

er has beendisconnected. Electrical shock can causeserious or fatal injury.

WARNING

:Surface temperatures of m

otor enclosuresm

ay reach temperatures w

hich can causediscom

fort or injury to personnelaccidentally com

ing into contact with hot

surfaces. Protection should be provided bythe user to protect against accidentalcontact w

ith hot surfaces. Failure to observethis precaution could result in bodily injury.

Lubrication Information

This is a ball or roller bearing motor. The bearings have been

lubricated at the factory. Motors that do not have regrease

capability are factory lubricated for the normal life of the

bearings. Washdow

n motors can not be lubricated.

LubricantBaldor m

otors are pregreased, normally w

ith Mobil

Polyrex EM unless stated on nam

eplate. Do not m

ixlubricants due to possible incom

patibility. Look for signs oflubricant incom

patibility, such as extreme soupiness visible

from the grease relief area. If other greases are preferred,

check with local Baldor representative for recom

mendations.

Relubrication Intervals (For m

otors with regrease

capability)N

ew m

otors that have been stored for a year or more should

be relubricated. Lubrication is also recomm

ended at theseintervals.

LUBRICATION INSTRUCTIO

NSC

leanliness is important in lubrication. Any grease used to

lubricate anti friction bearings should be fresh and free fromcontam

ination. Properly clean the grease inlet area of them

otor to prevent grease contamination.

1. Select service condition from Table 1.

2. Select lubrication frequency from Table 2.

LUBRICATION PRO

CEDUREBearings should be lubricated w

hile stationary and the motor

is warm

.1. Locate the grease inlet, clean the area, and replace the

pipe plug with a grease fitting.

2. Locate and remove the grease drain plug, if provided.

3. Add the recomm

ended volume of recom

mended lubricant

until clean grease appears at the grease drain, at thegrease relief, or along the shaft opening.

4. Replace the grease inlet plug and run the m

otor for two

hours.5. R

eplace the grease drain plug.
