you receive your motor, there are several things you should do im

1.O

bserve the condition of the shipping container and report any damage im

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−

ohms.

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

est point of the motor. V

storage.b.

Ball and roller bearing (anti−

greased every 6 months in accordance w

ith the Maintenance section of this m

anual.c.

Sleeve bearing (oil lube) m

otors are drained of oil prior to shipment.

The oil reservoirs m

ust be refilled to the indicated level with the specified lubricant, (see

Maintenance). T

distribute oil to bearing surfaces.d.

“Provisions for oil m
