Baldor Flex+DriveII Installation Manual page 9

WARNING: Be sure all wiring complies with the National Electrical Code and all regional and
local codes. Improper wiring may result in unsafe conditions.
WARNING: The stop input to this equipment should not be used as the single means of
achieving a safety critical stop. Drive disable, motor disconnect, motor brake and
other means should be used as appropriate. Only qualified personnel should
attempt to program, start-up or troubleshoot this equipment.
WARNING: Improper operation or programming of the drive may cause violent motion of the
motor and driven equipment. Be certain that unexpected motor movement will not
cause injury to personnel or damage to equipment. Peak torque of several times
the rated motor torque can occur during control failure.
WARNING: The motor circuit might have high voltages present whenever AC power is
applied, even when the motor is not moving. Electrical shock can cause serious or
fatal injury.
WARNING: If a motor is driven mechanically, it might generate hazardous voltages that are
conducted to its power terminals. The enclosure must be earthed/grounded to
prevent possible shock hazard.
WARNING: When operating a rotary motor with no load coupled to its shaft, remove the shaft
key to prevent it flying out when the shaft rotates.
WARNING: A regeneration resistor may generate enough heat to ignite combustible materials.
To avoid fire hazard, keep all combustible materials and flammable vapors away
from the brake resistors.
CAUTION: To prevent equipment damage, be certain that the input power has correctly sized
protective devices installed.
CAUTION: To prevent equipment damage, be certain that input and output signals are
powered and referenced correctly.
CAUTION: To ensure reliable performance of this equipment be certain that all signals to/from
the drive are shielded correctly.
CAUTION: Suitable for use on a circuit capable of delivering not more than the RMS
symmetrical short circuit amperes listed here at rated voltage.
Horsepower
1-50
CAUTION: Avoid locating the drive immediately above or beside heat generating equipment,
or directly below water or steam pipes.
