Section 1
General Information

Overview This manual contains general procedures that apply to Baldor Motor products. Be sure to read and

understand the Safety Notice statements in this manual. For your protection, do not install, operate or
attempt to perform maintenance procedures until you understand the Warning and Caution statements. A
Warning statement indicates a possible unsafe condition that can cause harm to personnel. A Caution
statement indicates a condition that can cause damage to equipment.

Important: This instruction manual is not intended to include a comprehensive listing of all details for all

procedures required for installation, operation and maintenance. This manual describes general
guidelines that apply to most of the motor products shipped by Baldor. If you have a question
about a procedure or are uncertain about any detail, Do Not Proceed. Please contact your Baldor
distributor for more information or clarification.

Before you install, operate or perform maintenance, become familiar with the following:

S NEMA Publication MG‐2, Safety Standard for Construction and guide

for Selection, Installation and Use of Electric Motors and Generators.

S The National Electrical Code
S Local codes and Practices

Limited Warranty

1. Most Baldor products are warranted for 18 months from the date of shipment to Baldor's customer from Baldor's
district warehouse or, if applicable, from Baldor's factory. Baldor Standard-E® standard efficient motors are
warranted for 24 months. Standard-E is limited to three phase, general purpose, 1-200 HP ratings that fall under
the Energy Policy Act (EPAct). Baldor Super-E® premium efficient motors are warranted for 36 months. Baldor
IEEE841 motors are warranted for 60 months. All warranty claims must be submitted to a Baldor Service Center
prior to the expiration of the warranty period.

2. Baldor will, at its option repair or replace a motor which fails due to defects in material or workmanship during the
warranty period if:

a. the purchaser presents the defective motor at or ships it prepaid to, the Baldor plant in Fort Smith, Arkansas

or one of the Baldor Authorized Service Centers and

b. the purchaser gives written notification concerning the motor and the claimed defect including the date

purchased, the task performed by the Baldor motor and the problem encountered.

3. Baldor will not pay the cost of removal of any electric motor from any equipment, the cost of delivery to Fort Smith,
Arkansas or a Baldor Authorized Service Center, or the cost of any incidental or consequential damages resulting
from the claimed defects. (Some states do not allow the exclusion or limitation of incidental or consequential
damages, so the above exclusion may not apply to you.) Any implied warranty given by laws shall be limited to
the duration of the warranty period hereunder. (Some states do not allow limitations on how long an implied
warranty lasts, so the above limitation may not apply to you.)

4. Baldor Authorized Service Centers, when convinced to their satisfaction that a Baldor motor developed defects in
material or workmanship within the warranty period, are authorized to proceed with the required repairs to fulfill
Baldor's warranty when the cost of such repairs to be paid by Baldor does not exceed Baldor's warranty repair
allowance. Baldor will not pay overtime premium repair charges without prior written authorization.

5. The cost of warranty repairs made by centers other than Baldor Authorized Service Centers WILL NOT be paid
unless first authorized in writing by Baldor.

6. Claims by a purchaser that a motor is defective even when a failure results within one hour after being placed into
service are not always justified. Therefore, Baldor Authorized Service Centers must determine from the condition
of the motor as delivered to the center whether or not the motor is defective. If in the opinion of a Baldor
Authorized Service Center, a motor did not fail as a result of defects in material or workmanship, the center is to
proceed with repairs only if the purchaser agrees to pay for such repairs. If the decision is in dispute, the
purchaser should still pay for the repairs and submit the paid invoice and the Authorized Service Center's signed
service report to Baldor for further consideration.

7. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

General Information 1‐1MN400

Safety Notice: This equipment contains high voltage! Electrical shock can cause serious or fatal injury.

Only qualified personnel should attempt installation, operation and maintenance of
electrical equipment.

Be sure that you are completely familiar with NEMA publication MG‐2, safety standards
for construction and guide for selection, installation and use of electric motors and
generators, the National Electrical Code and local codes and practices. Unsafe
installation or use can cause conditions that lead to serious or fatal injury. Only qualified
personnel should attempt the installation, operation and maintenance of this equipment.

WARNING: Do not touch electrical connections before you first ensure that

power has been disconnected. Electrical shock can cause serious
or fatal injury. Only qualified personnel should attempt the
installation, operation and maintenance of this equipment.

WARNING: Be sure the system is properly grounded before applying power.

Do not apply AC power before you ensure that all grounding
instructions have been followed. Electrical shock can cause
serious or fatal injury. National Electrical Code and Local codes
must be carefully followed.

WARNING: Avoid extended exposure to machinery with high noise levels. Be

sure to wear ear protective devices to reduce harmful effects to
your hearing.

WARNING: This equipment may be connected to other machinery that has

rotating parts or parts that are driven by this equipment. Improper
use can cause serious or fatal injury. Only qualified personnel
should attempt to install operate or maintain this equipment.

WARNING: Do not by‐pass or disable protective devices or safety guards.

Safety features are designed to prevent damage to personnel or
equipment. These devices can only provide protection if they
remain operative.

WARNING: Avoid the use of automatic reset devices if the automatic restarting

of equipment can be hazardous to personnel or equipment.

WARNING: Be sure the load is properly coupled to the motor shaft before

applying power. The shaft key must be fully captive by the load
device. Improper coupling can cause harm to personnel or
equipment if the load decouples from the shaft during operation.

WARNING: Use proper care and procedures that are safe during handling,

lifting, installing, operating and maintaining operations.
Improper methods may cause muscle strain or other harm.

WARNING: Before performing any motor maintenance procedure, be sure that

the equipment connected to the motor shaft cannot cause shaft
rotation. If the load can cause shaft rotation, disconnect the load
from the motor shaft before maintenance is performed. Unexpected
mechanical rotation of the motor parts can cause injury or motor
damage.

WARNING: Disconnect all electrical power from the motor windings and

accessory devices before disassembly of the motor. Electrical
shock can cause serious or fatal injury.

WARNING: Do not use non UL/CSA listed explosion proof motors in the

presence of flammable or combustible vapors or dust. These
motors are not designed for atmospheric conditions that require
explosion proof operation.
