1‐2 General Information

MN400

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.
